The proposed 20 per cent cuts in highway maintenance announced in July 1975 by the Minister for Transport have led the Department of the Environment to suggest that more use should be made of surface dressing instead of complete resurfacing. The author suggests that more attention be paid to the recommendations of Road Note 39, particularly to aftercare because most complaints are directed against loose chippings on new work. The paper considers when surface dressings should be applied, their purpose and means of ensuring a long life; the author claims that a found5 million saving could be made yearly if the average life of a surface dressing were increased from five to six years. The size of chippings used to prevent 'fatting-up' and stripping is dependent on the amount of traffic using the road, too many engineers compromise using 10mm chippings for all situations whereas Road Note 39 may recommend 20 mm for an inside lane, 14mm for a middle lane, and 10mm for an outside lane. Machine laid surfacing should only be used to repair riding surfaces or structural failure, sealing old surfaces and making a durable non-skid wearing coat can be more quickly and economically achieved by surface dressing. /TRRL/
