METHOD FOR PRODUCING BITUMEN COMPOSITIONS |
摘要 |
<p>The present invention relates to a bituminous composition for load-bearing paving applications. The bituminous composition comprising:
(a) a bitumen emulsion in an amount from 2% to 10% by total weight of the bituminous composition, wherein the bitumen emulsion comprises:
(j) hard bitumen in an amount from 50% to 75% by total weight of the bitumen emulsion, the hard bitumen having a penetration number of no more than 220 dmm at 25°C as determined according to ASTM standard method D5, and
(ii) an emulsifier in an amount from 0.05% to 2% by total weight of the bitumen emulsion; and
(b) an aggregate in an amount from 90% to 98% by total weight of the bituminous composition,
wherein the hard bitumen coats a surface of the aggregate in the bituminous composition, and the bituminous composition is characterized by a temperature of from 50°C to 140°C prior to load-bearing paving applications.</p> |
