Patent ID: 7811372

Claim:
A process for recycling an asphalt pavement, wherein the process comprises the steps of: a) heating and milling the asphalt pavement to provide a milled asphalt pavement; b) heating a rejuvenating agent or a composition comprising a rejuvenating agent and a polymer selected from the group consisting of styrenic block copolymers, olefinic copolymers, polyurethane and polyether-polyester copolymers, wherein the rejuvenating agent has a viscosity of from 200 to 60000 cSt (2×10 −4 to 6×10 −2 m 2 s −1 ) at 60° C. and comprises 10-90 weight % palm oil and 90-10 weight % bitumen, where the weight percentages are based upon the total weight of the composition to provide either a hot rejuvenating agent or a hot composition; c) adding either the hot rejuvenating agent or the hot composition to the milled asphalt pavement and mixing to provide a rejuvenated asphalt mix; and d) forming a rejuvenated asphalt pavement with the rejuvenated asphalt mix.
