A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets , whose primary function is to serve as public spaces, the main function of roads is transportation.
81-718: The A316 , known in parts as the Great Chertsey Road , is a major road in England , which runs from the A315 Chiswick High Road , Turnham Green , Chiswick to join head-on the M3 motorway at Sunbury-on-Thames . Its initial London section Chiswick Lane (to the Hogarth Roundabout ) heads south – following this it is a mostly straight dual carriageway aligned WSW . Outward from London
162-400: A road use tax , is payable on some vehicles used on the public road. The definition of a road depends on the definition of a highway; there is no formal definition for a highway in the relevant Act. A 1984 ruling said "the land over which a public right of way exists is known as a highway; and although most highways have been made up into roads, and most easements of way exist over footpaths,
243-411: A single carriageway road is converted into dual carriageway by building a second separate carriageway alongside the first, it is usually referred to as duplication , twinning or doubling . The original carriageway is changed from two-way to become one-way, while the new carriageway is one-way in the opposite direction. In the same way as converting railway lines from single track to double track ,
324-457: A 25 to 50 millimeter hole through the pavement into the sub-base with a dry-bit roto-hammer . Next, a two-part epoxy is poured into the hole – dyed for visual clarity. Once the epoxy hardens, technicians drill through the hole. If a void is present, the epoxy will stick to the core and provide physical evidence. Common stabilization materials include pozzolan -cement grout and polyurethane. The requirements for slab stabilization are strength and
405-614: A May 2009 report by the American Association of State Highway and Transportation Officials (AASHTO) and TRIP – a national transportation research organization – driving on rough roads costs the average American motorist approximately $ 400 a year in extra vehicle operating costs. Drivers living in urban areas with populations more than 250,000 are paying upwards of $ 750 more annually because of accelerated vehicle deterioration, increased maintenance, additional fuel consumption , and tire wear caused by poor road conditions. When
486-419: A double-wheeled, steel roller to insert the rod to the desired depth. After inserting the backer rod, the sealant is placed into the joint. There are various materials to choose for this method including hot pour bituminous liquid, silicone and preformed compression seals. Careful design and construction of roads can increase road traffic safety and reduce the harm (deaths, injuries, and property damage) on
567-634: A group of friends on 22 March 1991, is commemorated by a nearby memorial bench in Old Deer Park. On 6 October 1997, the A316 in Hanworth was the scene of one of the earliest recorded road rage incidents in Britain when Toby Exley, a chef from Teddington , and his partner Karen Martin, from Twickenham , both died when their car, a Ford Fiesta , collided with the central reserve after being hit by
648-413: A major two-level (and at one point, three-level) roadway in the downtown area, are being rebuilt with a designed service life of 100 years. Virtually all roads require some form of maintenance before they come to the end of their service life. Pro-active agencies use pavement management techniques to continually monitor road conditions and schedule preventive maintenance treatments as needed to prolong
729-413: A minority of the social housing . The non-urban parts, inclusive of the embanked water retaining reservoirs, are today for the most part Spelthorne's parks and lakes . The bulk of the rest is mostly narrow buffering land being arable farming, horse-grazing meadows and sheep grazing on the reservoir embankments and fringes with Green Belt legal status. Shopping is available in each of the towns and in

#1732780809584972-494: A road as a "Line of communication (traveled way) open to public traffic, primarily for the use of road motor vehicles, using a stabilized base other than rails or air strips. [...] Included are paved roads and other roads with a stabilized base, e.g. gravel roads. Roads also cover streets, bridges, tunnels, supporting structures, junctions, crossings and interchanges. Toll roads are also included. Excluded are dedicated cycle lanes." The 1968 Vienna Convention on Road Traffic defines
1053-510: A road as the entire surface of any way or street open to public traffic. In urban areas roads may diverge through a city or village and be named as streets, serving a dual function as urban space easement and route. Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel . Part 2, Division 1, clauses 11–13 of the National Transport Commission Regulations 2006 defines
1134-524: A road in Australia as 'an area that is open to or used by the public and is developed for, or has as one of its main uses, the driving or riding of motor vehicles.' Further, it defines a shoulder (typical an area of the road outside the edge line, or the curb) and a road-related area which includes green areas separating roads, areas designated for cyclists and areas generally accessible to the public for driving, riding or parking vehicles. In New Zealand,
1215-605: A sharp 35 degree correctional bend, before reaching St Margarets Roundabout, St Margarets , which is the junction for the short A3004 in both directions. The long western section after this in the Borough is Chertsey Road . It passes the London Road ( A310 ) Roundabout, before passing an unusually relocated and architecturally Grade I church, All Hallows (formerly Wren 's All Hallows, Lombard Street). The road passes Whitton Road Roundabout, also in north Twickenham , which
1296-1037: A speeding Vauxhall Senator which drove away. The driver of the Vauxhall Senator, Jason Humble, from Cove in Hampshire , was eventually arrested, found guilty at the Old Bailey on 2 April 1998 of manslaughter and sentenced to 12 years imprisonment. Road There are many types of roads , including parkways , avenues , controlled-access highways (freeways, motorways, and expressways), tollways , interstates , highways , thoroughfares , and local roads. The primary features of roads include lanes , sidewalks (pavement), roadways (carriageways), medians , shoulders , verges , bike paths (cycle paths), and shared-use paths . Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines
1377-549: A stable and energy-efficient drinking water supply to London, are bird reserves and in the case of the Queen Mary Reservoir, a sailing training centre. A similar percentage of land is covered by other lakes, mostly former gravel pits no longer pumped out of water. The 10-kilometre (6.2 mi) River Ash, Surrey starts and ends in the borough. Of recognised high importance to nature is Staines Moor , which alongside Sheepwalk Lake and wetlands , Shepperton are
1458-432: Is 40 years for new bitumen and concrete pavement. Maintenance is considered in the whole life cost of the road with service at 10, 20 and 30-year milestones. Roads can be and are designed for a variety of lives (8-, 15-, 30-, and 60-year designs). When pavement lasts longer than its intended life, it may have been overbuilt, and the original costs may have been too high. When a pavement fails before its intended design life,
1539-433: Is a non-destructive method of solving this problem and is usually employed with other concrete pavement restoration methods including patching and diamond grinding. The technique restores support to concrete slabs by filing small voids that develop underneath the concrete slab at joints, cracks or the pavement edge. The process consists of pumping a cementitious grout or polyurethane mixture through holes drilled through
1620-487: Is also common. Some road fixtures such as road signs and fire hydrants are designed to collapse on impact. Light poles are designed to break at the base rather than violently stop a car that hits them. Highway authorities may also remove larger trees from the immediate vicinity of the road. During heavy rains, if the elevation of the road surface is not higher than the surrounding landscape, it may result in flooding. Speed limits can improve road traffic safety and reduce
1701-485: Is another common procedure used to locate voids. It is recommended to do this testing at night as during cooler temperatures, joints open, aggregate interlock diminishes and load deflections are at their highest. Ground penetrating radar pulses electromagnetic waves into the pavement and measures and graphically displays the reflected signal. This can reveal voids and other defects. The epoxy/core test, detects voids by visual and mechanical methods. It consists of drilling

#17327808095841782-418: Is discovered it is removed, moisture content is managed and replaced with standard fill compacted to meet the design requirements (generally 90–95% relative compaction). Blasting is not frequently used to excavate the roadbed as the intact rock structure forms an ideal road base. When a depression must be filled to come up to the road grade the native bed is compacted after the topsoil has been removed. The fill
1863-557: Is due in 2027. Since the last boundary changes in 2003 the council has comprised 39 councillors representing 13 wards , with each ward electing three councillors. Elections are held every four years. The council offices are at Knowle Green in Staines. The building was opened in 1972 for the former Staines Urban District Council, shortly before that council was abolished in 1974 to be replaced by Spelthorne Borough Council. The borough council estimates it has 3.0 square kilometres (750 acres) of parks, including, from Shepperton upstream,
1944-553: Is largely ceremonial in Spelthorne. Political leadership is instead provided by the leader of the council . The leaders since 1995 have been: Following the 2023 election and subsequent by-elections and changes of allegiance up to July 2024, the composition of the council was: Five of the independent councillors sit together as the 'Independent Spelthorne Group', the other sits with the Conservatives. The next election
2025-451: Is made by the "compacted layer method" where a layer of fill is spread then compacted to specifications, under saturated conditions. The process is repeated until the desired grade is reached. General fill material should be free of organics , meet minimum California bearing ratio (CBR) results and have a low plasticity index . The lower fill generally comprises sand or a sand-rich mixture with fine gravel, which acts as an inhibitor to
2106-571: Is primarily due to environmental effects such as frost heaves , thermal cracking and oxidation often contribute, however accumulated damage from vehicles also contributes. According to a series of experiments carried out in the late 1950s, called the AASHO Road Test , it was empirically determined that the effective damage done to the road is roughly proportional to the fourth power of axle weight . A typical tractor-trailer weighing 80,000 pounds (36.287 t ) with 8,000 pounds (3.629 t) on
2187-522: Is some ambiguity between the terms highway and road . For the purposes of the English law , Highways Act 1980 , which covers England and Wales but not Scotland or Northern Ireland , road is "any length of highway or of any other road to which the public has access, and includes bridges over which a road passes". This includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks. Vehicle Excise Duty ,
2268-410: Is taken to preserve reference Benchmarks Roads are designed and built for primary use by vehicular and pedestrian traffic. Storm drainage and environmental considerations are a major concern. Erosion and sediment controls are constructed to prevent detrimental effects. Drainage lines are laid with sealed joints in the road easement with runoff coefficients and characteristics adequate for
2349-546: Is the native material underneath a constructed road. Road construction requires the creation of an engineered continuous right-of-way or roadbed , overcoming geographic obstacles and having grades low enough to permit vehicle or foot travel , and may be required to meet standards set by law or official guidelines. The process is often begun with the removal of earth and rock by digging or blasting, construction of embankments , bridges and tunnels , and removal of vegetation (this may involve deforestation ) and followed by
2430-597: Is the turning for Twickenham Rugby Stadium . The road then becomes dual-carriageway again and runs through south Whitton , passing The Stoop rugby ground and a prominent pub/hotel complex. After crossing the River Crane , the A316 leaves Richmond-upon-Thames and returns to Hounslow. Between Hospital Bridge Roundabout in Richmond-upon-Thames, and Apex Corner Roundabout, the road resumes the name Great Chertsey Road . After Apex Corner Roundabout, which

Distress and serviceability loss on concrete roads can be caused by loss of support due to voids beneath the concrete pavement slabs. The voids usually occur near cracks or joints due to surface water infiltration . The most common causes of voids are pumping, consolidation, subgrade failure and bridge approach failure. Slab stabilization
3726-455: The borough, which is an unparished area . On 27 February 2024, Spelthorne Borough Council unveiled their Corporate Plan for 2024-2028, highlighting their key priorities for the next few years. As of 2023, the council had £1.1 billion in borrowing, with the highest borrowing to income ratio of any council in England. The council has been under no overall control since 2020. Following

Fishing is open to all, subject to rod licensing, from the Thames Path National Trail and adjoining islands in Laleham and Staines as well as at lakes in Shepperton and Ashford. One rowing club is in the borough, at Laleham, with others nearby including Staines Boat Club across Staines Bridge from the town centre which organises
3888-551: The definition of a road is broad in common law where the statutory definition includes areas the public has access to, by right or not. Beaches, publicly accessible car parks and yards (even if privately owned), river beds, road shoulders (verges), wharves and bridges are included. However, the definition of a road for insurance purposes may be restricted to reduce risk. In the United Kingdom The Highway Code details rules for "road users", but there

The Jockey Club , as owner of Kempton Park Racecourse , is successor to the domain of the lords of the manor of Kempton – about 40% is a large nature reserve with its internal two large ponds abutting the Kempton Park Reservoirs Site of Special Scientific Interest , on Thames flood meadow . The borough has five reservoirs, covering more than 15% of land, which apart from their main use of ensuring
4131-441: The first pathways were the trails made by animals has not been universally accepted; in many cases animals do not follow constant paths. Some believe that some roads originated from following animal trails. The Icknield Way may exemplify this type of road origination, where human and animal both selected the same natural line. By about 10,000 BC human travelers used rough roads/pathways. In transport engineering , subgrade

After Chiswick Bridge, the A316 is Clifford Avenue until its next crossroads, the South Circular Road (A205) and the A3003 to Mortlake and Barnes at Chalker's Corner. It becomes the dual-carriageway Lower Richmond Road before crossing
4374-464: The growth of plants or other vegetable matter. The compacted fill also serves as lower-stratum drainage. Select second fill ( sieved ) should be composed of gravel , decomposed rock or broken rock below a specified particle size and be free of large lumps of clay . Sand clay fill may also be used. The roadbed must be "proof rolled" after each layer of fill is compacted. If a roller passes over an area without creating visible deformation or spring
4455-404: The highway system from traffic collisions. On neighborhood roads traffic calming , safety barriers , pedestrian crossings and cycle lanes can help protect pedestrians, cyclists, and drivers. Lane markers in some countries and states are marked with Cat's eyes or Botts dots. Botts dots are not used where it is icy in the winter, because frost and snowplows can break the glue that holds them to
4536-580: The hole. The injection device must also have a return hose or a fast-control reverse switch, in case workers detect slab movement on the uplift gauge. The uplift beam helps to monitor the slab deflection and has to have sensitive dial gauges. Also called joint and crack repair, this method's purpose is to minimize infiltration of surface water and incompressible material into the joint system. Joint sealants are also used to reduce dowel bar corrosion in concrete pavement restoration techniques. Successful resealing consists of old sealant removal, shaping and cleaning
4617-509: The latter three being London boroughs . The district was created on 1 April 1974 under the Local Government Act 1972 , covering two former districts which were both abolished at the same time: These two urban districts had been part of Middlesex prior to 1965, when they had been transferred to Surrey on the creation of Greater London. The new district was named after the medieval hundred of Spelthorne, which had covered

The proposal was generally opposed by the public and was not pursued. Spelthorne Borough Council provides district-level services. County-level services are provided by Surrey County Council . There are no civil parishes in
5103-515: The new carriageway is not always constructed directly alongside the existing carriageway. Roads that are intended for use by a particular mode of transport can be reallocated for another mode of transport, i.e. by using traffic signs . For instance, in the ongoing road space reallocation effort, some roads (particularly in city centers) which are intended for use by cars are increasingly being repurposed for cycling and/or walking . Like all structures, roads deteriorate over time. Deterioration

Road conditions are the collection of factors describing the ease of driving on a particular stretch of road, or on
5265-506: The owner may have excessive repair and rehabilitation costs. Some asphalt pavements are designed as perpetual pavements with an expected structural life in excess of 50 years. Many asphalt pavements built over 35 years ago, despite not being specifically designed as a perpetual pavement, have remained in good condition long past their design life. Many concrete pavements built since the 1950s have significantly outlived their intended design lives. Some roads like Chicago 's Wacker Drive ,

The type of road surface is dependent on economic factors and expected usage. Safety improvements such as traffic signs , crash barriers , raised pavement markers and other forms of road surface marking are installed. According to
5427-576: The presence or absence of a made road has nothing to do with the distinction. Another legal view is that while a highway historically included footpaths , bridleways , driftways, etc., it can now be used to mean those ways that allow the movement of motor vehicles , and the term rights of way can be used to cover the wider usage. In the United States, laws distinguish between public roads , which are open to public use, and private roads , which are privately controlled. The assertion that
