AGGREGATES FOR SKID-RESISTANT ROADS

This report reviews work that has been carried out at TRRL and elsewhere with the object of finding new sources of highly polish-resistant (high-psv) road aggregates. It covers both conventional aggregates (particularly gritstones and blastfurnace slags) and specially manufactured synthetic materials. These include calcined bauxites, gritty synthetic aggregates, porous aggregates, improved blastfurnace slags, shaped aggregates, calcined rocks and synthetic gritstones. The work reviewed has shown that Britain has large potential sources of high-psv aggregates, that calcined bauxites are better than almost all other materials and that there is a considerable range of synthetic materials that could be manufactured to provide aggregates with properties lying between those of the best natural rocks and calcined bauxite. /Author/TRRL/
