This section of the LHDG defines:
- The standard methods and materials required for construction or otherwise completion of all aspects of new highway that the council is expected to adopt.
- The council’s policy relating the use of alternative or innovative materials.
- The council’s limited palettes of materials for use within highway schemes.
- The council’s policy relating to commuted sums, the assets included within our commuted sums schedule and the rates charged for their maintenance.
- The council’s specification for highway works, including public rights of way.
- The council’s standard drawings and specification.
The standard construction requirements and materials set out in the in this section of the LHDG are based on national and local standards and guidance, including:
- Design Manual for Roads and Bridges
- The Manual of Contract Documents for Highway Works (MCHW) - Volume 1 Specification for Highway Works
- The SuDS Manual (CIRIA Report C753; 2015)
- LCC Carriageway Skidding Resistance Procedure
These documents must be applied to all works to ensure that highways function safely, can be cost effectively maintained and accord with principles of quality, durability, maintainability and environmental sustainability.
In all cases MCHW Specification for Highway Works should be considered “the specification,” and the council's specification should be considered a set of Appendices covering specifics unique to the council.
The council’s acceptable highway surfacing materials can be found in the:
These documents should be read in conjunction with relevant standard drawings and specifications.
