But what wasn’t clear Highways England believes a connected was exactly which aspects of the surface users country is better for everyone. The company works wanted to be improved and why. hard to deliver the safest, smoothest, most Transport Focus and Highways England have reliable connections possible. In 2015/2016 therefore worked together to research just that. 1471 lane miles of resurfacing was carried out Our purpose being to ensure that the views of – 23 per cent higher than the original target. those using the roads shape decision-making in But Highways England is not complacent. this area. That’s why Transport Focus and Highways England The research shows that what road users want are both using this research to help inform the is not complicated. They want a surface without Government’s second Road Investment Strategy dips, bumps, potholes, undulations or deep ruts (RIS 2), covering 2020-25. Separately, Highways – in other words continuously smooth. They also England is considering the recommendations want clearer white lines and ‘cats eyes’, which Transport Focus has made in light of this users regard as part of the surface and research. 2 1 Road users’ priorities for improvement: car and van drivers and motorcyclists and Road users’ priorities for improvement: heavy goods vehicle drivers (2015) Key findings Why does surface quality matter? What is a good surface? In this research road users were not saying To a road user a good quality road surface: Highways England’s roads are in a poor state. • is continuously smooth, without dips, bumps, However they were saying that surface quality potholes, undulations and deep ruts on England’s strategic roads matters to them. • has white lines and ‘cats eyes’ in excellent condition There were three main reasons. – road users think of these as part of the surface and • Precisely because Highways England’s roads are not something separate to do with signage important strategic roads, users want them maintained • is preferably made of asphalt rather than concrete to a high standard. Those taking part were unsurprised because it is considered quieter to drive on and to learn that the earlier study had found the area to viewed as less bumpy. be users’ highest priority for improvement. • Road users think surface defects on 70mph roads with huge volumes of traffic – a characteristic of much of the strategic road network (SRN) – must in some way compromise safety. Those taking part mentioned having to swerve around faults in the road, feeling unsafe when white lines and ‘cats eyes’ are not clear, and experiencing water not draining properly from the carriageway. Motorcyclists cite safety in relation to surface defects to an even greater extent than drivers of other vehicles, while caravan drivers mention the dangers of being ‘caught’ in ruts caused by heavy vehicles using the inside lane. • A continuously smooth surface gives a more comfortable journey experience. Road users have a clear preference for an SRN where the surface is smooth and free from defects – it is simply a more pleasant experience. Road users with particular disabilities can experience physical discomfort as a result of poor road surface. A surface which is not continuously smooth impacts on journey comfort and is viewed as less safe. Road users cite surface defects as being the cause of poor driving, such as vehicles not returning to the inside lane to avoid deep ruts. Some perceive that smooth surfaces lead to smoother traffic flow and therefore fewer delays. Where a defect has been there for a long time, frequent users lose faith that maintenance standards are right or that contractors are adhering to them. It is important to highlight that the condition of Highways England’s assets has a more direct bearing on customer experience than is the case with most regulated utilities. Road users see and feel the bumps in the road in a way that consumers do not, generally, see and feel leaks from a worn-out water main. 3 Road surface quality: what road users want from Highways England Where would road users like Variation by vehicle type and driver to see improvements?

  • Surface Pavement Materials Used Ion Urban Areas
    Session 4 - Specific techniques and innovation Paper : Pavement surface materials used in urban areas Authors : Egbert BEUVING (EAPA) - Netherlands Jean-Paul MICHAUT (COLAS) - France Pavement surface materials used in urban areas -The range of urban materials- Egbert Beuving (EAPA) and Jean-Paul Michaut (COLAS) Summary A wide variety of pavement surface materials have been used in urban areas. The choice of the surface material depends on a range of rational and irrational arguments. In former days the availability of the materials was a dominant factor. Nowadays a broad scale of materials is available and functional requirements play an important role in the decision for a certain pavement type and surface layer now. The materials available are: • Bituminous bound materials (asphalt concrete, mastic asphalt) • Cement bound materials (concrete, concrete elements) • (Small) paving elements (block pavers, modular materials, stone, terracotta) • Composite pavements (a combination of the above mentioned ones) In urban areas there is a wide variety of pavement users, as there are: pedestrians, wheelchair- users, parents with prams, roller-skates, bicyclists, scoot-mobiles, motorists, passenger cars and trucks. The choice of the surface material depends on the (functional) requirements. Some of these requirements are the same as for highways; other ones might depend on the local situation. Additional requirements for urban areas might be a certain surface texture or colour for a certain image, easy to repair to guarantee the accessibility of houses, shops and other buildings, noise reducing, open for water infiltration, smooth to avoid vibrations and easy to open for accessing sewerage, gas and water systems. There might also be a need for flexible materials for creating ramps, roundabouts, cables and wiring.

Skłodowskiej-Curie St., 41-819 Zabrze, Poland * Correspondence: [email protected] or [email protected]; Tel.: +48-225-617-553 Received: 27 October 2017; Accepted: 5 January 2018; Published: 7 January 2018 Abstract: Along with house heating and industry, emissions from road traffic (exhaust and tire, brake, car body or road surface abrasions) are one of the primary sources of particulate matter (PM) in the atmosphere in urban areas. Though numerous regulations and vehicle-control mechanisms have led to a significant decline of PM emissions from vehicle exhaust gases, other sources of PM remain related to road and car abrasion are responsible for non-exhaust emissions. Quantifying these emissions is a hard problem in both laboratory and field conditions. First, we must recognize the physicochemical properties of the PM that is emitted by various non-exhaust sources. In this paper, we underline the problem of information accessibility with regards to the properties and qualities of PM from non-exhaust sources. We also indicate why scarce information is available in order to find the possible solution to this ongoing issue.
