WEARABLE MIXTURE ENDOWED WITH FREEZE INHIBITION FUNCTION, PAVEMENT SYSTEM AND PAVEMENT

摘要

PROBLEM TO BE SOLVED: To provide a silica sand asphalt mixture or a pavement mixture having a function equal thereto which is endowed with a freeze inhibition function, a wearable pavement system and a pavement body which is endowed with a freeze inhibition function by using the mixture. SOLUTION: A pavement mixture is obtained by adding not less than 2 pts.wt. freeze inhibitor having a chloride or a compound having a freeze inhibition function equal thereto as the major component to a silica sand asphalt mixture or a wearable pavement mixture having a freeze function equal thereto. A freeze inhibition pavement system employs the pavement mixture as a wear layer on the surface layer of a pavement.
