The article describes the resurfacing of the M4 for a 1200 metre section spanning the length of Junction 22 Newhouse Roundabout. It is explained that the whole stretch was re-covered, rather than patched, because there was complete loss of chippings and in some areas the surfacing had come away. Limitations such as the maintenance of traffic flow in the summer peak and the need to do the work in frost-free conditions, dictated an autumn work programme which could be carried out quickly. There is a description of the use of the cold planers and the modifications made to maintain an even cut. The speed of cutting and deterioration of the picks are included. The machines used required a separate pick-up operation for the debris: the rate at which the pick-up is achieved limits the speed of the overall operation, and estimates are given of the optimum speed. Alterations to traffic movement are briefly reported: few delays occurred. Finally costings of the scheme are presented, indicating that the scheme was quick and economical. /TRRL/
