Abstract

PURPOSE: The titled filler, consisting of a dry unburned portland cement raw material powder with a low moisture content, a specific hydraulic modulus, silica modulus, iron modulus, and activity index, and capable of improving the abrasion resistance of an asphalt composition.
CONSTITUTION: A filler consisting of a mixed material powder of unburned portland cement, taken out of a step from the outlet of a raw material pulverizer and the inlet of a primary burning furnace, and having a hydraulic modulus (CaO/SiO2+Al2O3+Fe2O3) of 1.7W2.3, a silica modujus (SiO2/Al2O3+ Fe2O3)of 1.8W3.2, an iron modulus (Al2O3/Fe2O3)of 0.7W2.0, an activity index (SiO2/Al2O3) of 2.5W8.0, a low moisture content, preferably ≤0.1wt%, and a fineness of 200W 7,000cm2/g expressed in terms of the specific surface area measured by the Blaine method. The addition of the resultant filler in an amount of 3W15wt% to an aggregate improves the abrasion resistance compared with the addition of the limestone powder, and the amount of asphalt to be used is reduced by about 20%.
