Abstract

Heavy duty road surfaces and industrial floors contain a bitumen, which may be ordinary, oxidized or liquid bitumen, 1-20% of polyurethane from a polyol or polyester and a polyisocyanate, hard granules from hard rock, of a particle size such as 0-12mm or 0-18mm of which 0-6% passes an 80 mu screen and a fine filler having a dehydrating action e.g. cement, chalk, plaster, silica gel, which have been, pref. treated to increase their dehydrating props. The fine filler and fraction of the hard rock granules passing an 80 mu screen are 0-7% of the total filler. The surfaces are formed by first mixing the granules, the fine filler and the polyol, then mixing the bitumen and polyisocyanate, and finally mixing the two mixtures. The surfaces are stable, mechanically resistant, and show durability in service.
