Disclosed is an asphalt adhesive, coating or sealant composition comprising a base polymer or copolymer material and at least one ester containing plasticiser having a molecular weight less than about 3,000 grams per mole and a structure according to formula (I). The composition resists softening of the asphalt at elevated temperatures up to 140°F (60°C). In a particular embodiment, the plasticizer is oxydiethylene dibenzoate, castor oil, and glycerol triacetate. In a particular embodiment, the base polymer or copolymer that includes polyurethanes, silylated polyurethanes,and silylated polyethers. |
