The report provides:-

  • a translation of all the names of all asphalt mixtures used in London from the old obsolete British Standards to the new nomenclature We have been assured by the supply industry that the use of these materials will be cost neutral.
  • a core list of preferred mixtures. Increased use of these will lead to improved quality and help to keep costs down.
  • additional specification clauses, and draft Appendix 7/1 clauses and Bills of Quantities
  • Notes for Guidance on the selection of materials for the various Road Classes as defined in the NRSWA gazetteer.
  • Useful background Notes For Guidance on pavement maintenance issues such as sustainability, skid resistance and tyre noise.

The document is an indispensable aid to your implementation of the new European Standards. Please raise any detailed questions with our Project Consultant Ian Walsh (Jacobs) who has agreed to provide help.
