Surface Dressing Code of Practice

Read document description

This sixth edition of the Code of Practice has been produced by the RSTA Surface Dressing Technical Committee. It has been reviewed in the context of the European Standard for Surface Dressing BS EN 12271 published in September 2006 along with the national guidance document PD6689:2009. This document has been peer reviewed by ADEPT Soils, Materials, Design and Specifications Committee. To the highway engineer, surface dressing offers a quick, efficient and cost-effective way of maintaining skid-resistant and waterproofing road surfaces. To obtain the best results it is necessary to give careful consideration to a wide range of detail and to plan and design the work carefully. The speed of the surface dressing operation and the short duration of time during which motorists are inconvenienced is also an important issue. The purposes of surface dressing are to waterproof the road surface, to arrest disintegration, to provide texture, and provide a skid-resistant surface. This latter quality can play a major part in accident reduction and was highlighted by the initiative of the Department of Transport in 1987 when the Minister introduced minimum mean summer SFC values for motorways and trunk roads. The importance of surface texture as provided by surface dressing has been highlighted by TRL report LR 286, which stresses that texture depth is important under both wet and dry conditions. Up to date guidance is available in the Design Manual for Roads & Bridges (DMRB): Volume 7 HD 28. The DMRB is available on line at A useful way of comparing the effectiveness of a dressing, or other maintenance work, is to express it in terms of a ‘cost life index’. This is the cost per square metre of the work divided by the service life in years. It provides a measure of the “value for money” which the highway authority is achieving. A low ‘cost life index’ and “high value for money” is the result of high-quality work. The purpose of this Code is to identify the important aspects of the process, and to refer to other documents relating to good surface dressing practice and so give practical guidance on achieving high quality.

PAS 68:2013 Impact test specifications for vehicle security barriers

Read document description

PAS 68 has been prepared to address the needs of organisations who want assurance that vehicle security barriers will provide the level of impact resistance they are aiming for. Many systems are available that are either promoted or considered suitable for use as vehicle security barriers. As their characteristics differ in both function and form, a comparative means of assessing their performance is required. PAS 68 identifies impact test methods, tolerances, test vehicle type and vehicle performance criteria that need to be met in order to conform to PAS 68. Design guidance for installing barriers is provided in PAS 69.

Traffic Signs Manual Chapter 4: Warning Signs (2013)

Read document description

2013 UPDATE - Through the Traffic Signs Manual, the Department for Transport provides guidance to traffic authorities and sign designers on good practice in respect of the design and use of traffic signs in order to provide appropriate and adequate information for road users. The Manual is published by TSO as a number of discrete chapters each of which deals with a specific signing topic. We have made changes to Chapter 4 to bring it up to date following the amendments that were made to the Traffic Signs Regulations and General Directions 2002. Chapter 4 of the Manual is concerned with signs that warn road users of hazards ahead and was last updated in 2008. The main changes relate to the signing of low bridges and on using the new triangular warning sign that indicates maximum height in both imperial and metric units. Bridge strikes, where vehicles, their loads or equipment collide with bridges, are a significant and recurring problem and the revised guidance gives highway authorities up to date information and demonstrates the Department’s ongoing commitment to tackling the risk.

Delivery of Local Road Safety

Read document description

The Department for Transport commissioned AECOM, in association with the Tavistock Institute, to design and deliver a three-year independent evaluation of the delivery of local road user safety. The evaluation was commissioned to consider the following objectives: •to evaluate the different strategies and plans for delivering road user safety; •to assess what is being delivered, the key processes and how efficient local authority practices are; and •to identify lessons and areas of good practice in road user safety investment.
