Embodiment 1
[0047] A kind of bitumen modifier, by weight, its raw material is composed of: 10 parts of waste tire rubber powder, 6 parts of polyethylene waste, 3 parts of styrene-butadiene-styrene block copolymer, styrene- 3 parts of isoprene-styrene block copolymer, 3 parts of terpene resin, 6 parts of solvent naphtha, 0.6 part of alcohol ether carboxylate interface agent. Wherein, the softening point of the terpene resin is 90-110° C., and the acid value is less than 20 mgKOH / g. The solvent oil is a compound of waste edible oil and furfural oil, and its weight ratio is 1:1; the alcohol ether carboxylate interface agent is AEC-9Na.
[0048] The specific preparation method of asphalt modifier is: solvent oil, alcohol ether carboxylate interface agent, styrene-butadiene-styrene block copolymer, polyethylene waste, waste tire rubber powder, styrene-iso Pentadiene-styrene block copolymer and terpene resin are sheared and ground at 180°C according to the weight ratio and mixed uniformly, ext...
