MAINTAINING METHOD FOR PAVEMENTS USING AGGREGATES BLENDED WITH WASTE ASCONS AND MODIFIED ASPHALT EMULSIONS

摘要

PURPOSE: A maintaining method for pavements using aggregates blended with waste ascon and modified asphalt emulsion are provided to guarantee the durability and the application of waste ascon by forming a thin surface layer using slag maxed aggregate and modified asphalt emulsion. CONSTITUTION: A damaged part of pavement is cut. The cut surface is cleaned and tex-coated. A waste ascon blended mortar layer(200) is formed by pouring waste ascon blended mortar on the surface. The modified asphalt emulsion consisting of asphalt, emulsifier, acid, specialty polymer plastic, store characteristic improvement material, additive for adjusting curing time, and water.
