Title:
MODIFIED ASPHALT COMPOSITION CONTAINING STYRENE-BASED BLOCK COPOLYMER AND VEGETABLE WAX
Document Type and Number:
WIPO Patent Application WO/2014/175471
Kind Code:
A1
Abstract:
The present invention relates to a modified asphalt composition comprising a styrene-based block copolymer and a vegetable wax as modifiers. Compared to typical asphalt compositions comprising only a styrene-based block copolymer, the modified asphalt composition of the present invention has a low viscosity at high temperatures, thereby enabling the manufacture and application of modified asphalt even at low temperatures, and also exhibits excellent elongation characteristics at low temperatures, thereby minimizing low-temperature fatigue cracking even in cold areas.
