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 Appendix B and Appendix 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
