DENSE TAR SURFACING FOR ROADS AND OTHER PAVED AREAS

This British standard specifies the composition, manufacture, testing and transport of dense tar surfacing (DTS), defined in BS 892 as a hot process wearing course material consisting of aggregate, filler and road tar, in such gradings and proportions that when spread and compacted it provides a close textured impervious mixture. Notes on the use of DTS are given in Appendix A. Recommendations for laying the materials and for measuring their temperatures are included in Appendices B and C. The mixtures specified are as follows: DTS (crushed rock or slag fine aggregate) 35% coarse aggregate content 14 mm and 10 mm nominal size. 50% coarse aggregate content 14 mm and 10 mm nominal size. Dts (sand fine aggregate) 35% coarse aggregate content 14 mm and 10 mm nominal size. 50% coarse aggregate content 14 mm and 10 mm nominal size. /TRRL/
