A METHOD FOR PREVENTING CONSTRUCTION JOINT CRACK OF ASPHALT CONCRETE PAVED

摘要

The present invention relates to a method of preventing asphalt concrete pavement seam cracking, and more particularly, in installing asphalt concrete on a road, in which rainwater is penetrated, cracked, sag phenomenon and continuous traffic load due to seam compaction and poor adhesion of asphalt concrete. In order to prevent plastic deformation caused by consolidation due to condensation, rainwater penetrates into the joints of asphalt concrete using the emulsified asphalt, which is formed by adding emulsifier, acid, etc. This prevents cracks, sagging and plastic deformation to be lowered to extend the life of the road, and to reduce the cost of the road repair is very economical asphalt concrete pavement joint prevention method.;Asphalt, Concrete, Joint, Crack, Compaction, Plastic Strain, Rainwater Penetration, Sag
