Abstract

PURPOSE: An asphalt solution resulting from dissolution of asphalt in a mineral oil is mixed with powder particles heated to give said powder particles having water- repellent asphalt film on the surface, thus being used in waterproofing works.
CONSTITUTION: Asphalt is dissolved in a mineral oil, preferably consisting of the fraction boing at from 180W400°C to prepare an asphalt solution at first. The asphalt solution is mixed with powder particles, e.g., river sand, heated to 180W 200°C to give the objective water-repellent powder particles having asphalt coating layers on the surface. The amount of the asphalt used is 2wt% or less based on the powder particles.
EFFECT: The amount of the asphalt required can be lessened and waste oil may be used as the solvent.
