PAVEMENT MATERIAL HAVING WATER HOLDING CAPACITY AND A MANUFACTURING METHOD THEREOF CAPABLE OF RESTRAINING A RISE IN THE SURFACE TEMPERATURE OF A ROAD OR A BUILDING BY EVAPORATION HEAT

摘要

PURPOSE: A pavement material having water holding capacity and a manufacturing method thereof are provided to improve the absorption of water and to restrain a rise in temperature of a road surface by the evaporation heat of water by evaporating absorbed water gradually. ;CONSTITUTION: A pavement material having water holding capacity is manufactured by mixing 20~30 weight percent cement and 1~5 weight percent water retention agent to 100 weight percent aggregate of 0.1~10mm, wherein the water retention agent is composed of diatom soil or zeolite, or a mixture of diatom soil and zeolite.;COPYRIGHT KIPO 2011
