Designing for Walking

Read document description

This document explains how facilities for walking should be designed, following on from how they are planned, which is covered in Planning for Walking. Well-designed facilities that follow desire lines, are clutter-free, and are legible to all users will assist in enabling walking journeys and improve the experience of those already walking. The design of facilities should also consider the volumes of people walking along (actual or desired) or crossing streets, and the solutions will depend on a variety of considerations. The needs of all users should be carefully taken into account and prioritised as appropriate.

Management of Highway Structures Complementary Guidance

Read document description

Management of Highway Structures: A Code of Practice was published in September 2005. Since then Government Policy in respect to highway and structures management has developed and evolved in a number of areas, including the introduction of new statutory duties on highways authorities. There have also been developments/advances with regard to recognised good practice. To assist users of the Code, the Roads Liaison Group has prepared this complementary guidance which takes account of these changes and developments. Where appropriate, the complementary guidance provides details of where to find up-to-date information that can assist with the implementation of the good practice set out in the Code. Users of the Code should treat this complementary guidance as up-to-date and having the same status as the Code. Where paragraphs have been amended, they supersede the ones in the Code.

TRL PRR 362 Performance of impregnants

Read document description

Since the early 1990s there has been a requirement to utilise hydrophobic pore-lining impregnants to provide additional durability on Highways Agency structures subjected to aggressive conditions – primarily arising from the use of de-icing salts. The material that has generally been used as an impregnant is monomeric alkyl (isobutyl) – trialkoxy silane. More recently alternative materials have come onto the market and the Highways Agency (HA) has updated its requirements to include new test methods to assess the effectiveness and performance of pore-lining impregnants. The purpose of these tests is to facilitate the acceptance of these alternative materials. A series of experiments was undertaken to assess the effectiveness of available impregnants for suppressing the ingress of chloride ions into concrete and their long term effectiveness in service. Laboratory tests demonstrated that the ingress of chloride ions by ponding and water uptake by sorptivity was significantly reduced by treatment with the pore-lining impregnants. By contrast, pore-blockers provided only very limited resistance to chloride ingress and virtually no resistance to water uptake. A limited number of tests were also undertaken on cores extracted from bridges.

DMRB Volume 1 Highway Structures: Approval Procedures and General Design - Section 2 Other Procedural Documents: BD 95/07 Treatment of Existing Structures on Highway Widening Schemes

Read document description

Making better use of existing roads, including the widening of highways, is consistent with Government objectives. The intention should be to reuse as much existing infrastructure as possible. Widening gives rise to many issues affecting existing structures. The treatment of these issues can have a major influence on the design and cost of the widening scheme. Valuable experience has been gained from a number of previous schemes, but this has not been recorded centrally and is not readily available to others in the form of advice. This Standard has been produced to set out the principles to be applied and to promulgate advice and guidance relating to the treatment of structures affected by widening schemes.

TRL PPR 215 The effectiveness of sub-standard shear reinforcement in bridge decks

Read document description

This report contains the results of a study to examine the contribution made to the shear capacity of reinforced concrete beams of shear reinforcement that does not comply with the detailing requirements of the UK bridge design code. The main goal was to determine whether it is possible to relax the detailing requirements and remove any unnecessary conservatism that might exist in BD 44. The report contains the results of a literature review as well as the conclusions of a testing programme to investigate different details. These details include wide or varying spacing of links, links with less than the nominal area, and links not surrounding the main tension steel. The report discusses areas where relaxations may be possible, drawing on the conclusions of the literature review, the test programme and the analysis.
