ABSTRACT:
This invention provides a novel granular asphalt which comprises granules having the size of from about 0.074 to about 10 mm and being in the shape of a polyhedron having at least one acute angle. The granular asphalt has excellent properties. In particular, it can be melted rapidly and easily with small thermal capacity and slight heating, without causing thermal decomposition, denaturing and air pollution. The granular asphalt is useful, for example, for producing asphalt compound, cutback asphalt, rubberized asphalt, etc., for use in water-proofing, paving, sealing, etc., and for making asphalt block, asphalt tile, asphalt roofing, tarpaulin paper, flooring sheet, paint and varnish, etc.
