ADDITIVE FOR RECLAMATION OF ASPHALT, RECLAIMED ASPHALT PAVEMENT MATERIAL CONTAINING SAME, MODIFIED ASPHALT, AND ASPHALT PAVEMENT MATERIAL CONTAINING SAME

摘要

An additive for the reclamation of asphalt which is obtained by adding straight asphalt to a mixture that consists of both a waste animal or vegetable fat or oil and a waste mineral oil exhibiting a kinematic viscosity of 10 to 40mm2/s at 60°C, mixing the resulting system, and then heating the obtained mixture to remove aromatic substances. The additive enables a deteriorated asphalt to recover physical properties to levels equal or superior to those attained by a conventional additive for the reclamation of asphalt. Further, the additive has a low content of components that may exert influence on the environment or the human body exhibits high fluidity at ordinary temperatures and is extremely uncostly.
