Design Manual For Roads And Bridges




DMRB was originally published in 1992 and covered roads in England and Wales. Its remit was subsequently extended to include roads in Scotland and Northern Ireland. DMRB is managed by the Highways Agency on behalf of the agencies responsible for trunk roads in Scotland, Wales and Northern Ireland.

The volumes contain technical requirements and guidance on a wide range of topics, such as:

a) technical and other procedures and methods to be employed;

b) analytical criteria to be used;

c) appraisal requirements;

d) dimensional requirements;

e) numerical and statistical data.

In terms of scheme appraisal, the Cost-benefit and Environmental Impact Assessment methods set out in DMRB provide important inputs into the approach used to appraise road schemes, called the New Approach To Appraisal .

The volumes are:

Volume 1 - Highway Structures: Approval Procedures and General Design

Volume 2 - Highway Structures: Design (Substructures and Special Structures), Materials

Volume 3 - Highway Structures: Inspection and Maintenance

Volume 4 - Geotechnics and Drainage

Volume 5 - Assessment and Preparation of Road Schemes

Volume 6 - Road Geometry

Volume 7 - Pavement Design and Maintenance
