ASPHALT MIXTURE FOR THIN LAYER PAVEMENT AND METHOD OF REPAIRING PAVEMENT SURFACE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an asphalt mixture for a thin layer pavement and a method of repairing a pavement surface using the same by which an existing pavement surface can be paved with a thin layer to have sufficient strength and durability.;SOLUTION: An asphalt mixture for a thin layer pavement uses an aggregate which has a maximum particle diameter of 4.75-5 mm and in which the passage weight percentage at a particle diameter of 2.36 mm is 45-65%. The asphalt mixture uses modified asphalt produced by adding and mixing a modifier, mainly composed of paraffin-based hydrocarbon produced by burning of polymer-based synthetic resin materials having self-burning performance at a softening point of 100-120°C, to and with the asphalt at a compounding ratio of 3-10 wt.%. The asphalt mixture is provided by adding the modified asphalt at a compounding ratio of 6-8 wt.% and heating and mixing it with the aggregate.;COPYRIGHT: (C)2012,JPO&INPIT
