This is one in a series of Traffic Advisory Leaflets providing guidance on methods of working and innovative techniques aimed at reducing traffic congestion due to road works. The series is aimed at utility companies, highway authorities, contractors, equipment suppliers and others involved in road (or street) works. Each leaflet in this series is based on research carried out by TRL Limited on behalf of the Department for Transport and Transport for London. There are occasions where it is sometimes necessary to immediately reinstate an excavation to open roads to traffic at peak times during the overall site occupation period. Reinstating with temporary backfill (see Figure 1) is one way of achieving this and is a useful alternative in certain circumstances to road plates. Both techniques have their advantages and disadvantages and the choice of which to use will depend on the site-specific circumstances. This leaflet gives guidance on the use of temporary backfill and discusses the factors to be taken into account when deciding whether it is appropriate for any given site. Guidance on the use of road plates can be found in TAL 6/14 Using road plates at road works. (Author/publisher)
