Abstract

PURPOSE: To obtain a stable road pavement material having small temperature sensibility at higher and lower temperatures, utilizing asphalt properties and lubricant characteristics depending upon its types, obtaned by blending slaked lime with unswollen mineral clay, etc. under heating.
CONSTITUTION: Blown asphalt as a base material is blended with lubricant, straight asphalt of lubricant waste liquor, one or more finely divided powder selected from slaked lime volcanic ash, unswollen mineral clay, etc. under heating. For example, 10W30wt% lubricant having different types and properties depending upon its use, 50W70wt% asphalt with 60W80 penetration, and 10W50wt% of slaked lime, volcanic ash, and a caking mineral are added to a hot tank and heated at 200°C to give greasy compound. 50W40wt% greasy compound is added to blown asphalt heated at 180W220°C.
