ABSTRACT:
A bitumen and asphalt modifier comprises thermoplastic elastomeric copolymer and an effective amount of a fibrillated polytetrafluoroethylene and molybdenum disulfide particles. The thermoplastic elastomeric copolymer comprises two incompatible polymers forming a two-phase copolymer including a thermoplastic end block polymer and an elastomeric mid block polymer. The asphalt modifier is made by mixing together under high shear particles of a thermoplastic elastomeric copolymer, fibrillatable polytetrafluoroethylene and molybdenum disulfide until the fibrillatable polytetrafluoroethylene is substantially fibrillated and combined with the thermoplastic elastomeric copolymer.
