TRAFFIC CONTROL AND 'AFTER-CARE' IN ROAD SURFACE DRESSING

The main objection to surface dressing is the presence of loose chippings on new work. This paper describes modern methods of removing surplus chippings and of controlling traffic speed for a few hours. Initial adhesion of the chippings is achieved by rolling with road rollers whereas second stage compaction is brought about by traffic whose speed must be controlled until the dressing is traffic compacted and swept clean. Advantages and disadvantages of completing one lane at a time, or alternatively, completing the full width of carriageway are described and recommendations are made for the sequence of work. The importance of the amount and type of traffic is stressed; different methods of traffic control are essential for different categories of road. Precautions are necessary when surface dressing on difficult sites such as roundabouts, road junctions and bends on high speed roads, where traffic stress is high. /TRRL/
