Abstract

PURPOSE: Inexpensive stone particles for asphalt pavement that are preapred by drying fine particles of the coral stones produced in Okinawa Prefecture with a specific particle size range.
CONSTITUTION: Coral soft stones that is composed mainly of limestone and produced in Okinawa Prefecture in large quantities are dried, crushed, sieved to give fine particles with 13 mm or smaller mesh, which are further pulverized with ball mills, The resulting powder is sent mechanically with wind and sucked and collected in a specific size range.
