Overview

High Elasticity Waterproof Asphalt is a middle-course asphalt pavement method that increases the durability of the pavement by forming a waterproof layer using HE modifier and suppressing the occurrence of reflective cracks.

Properties

01Waterproof due to mixture with air void less than 1%
02Excellent stress relief and crack resistance
03Excellent reflective crack resistance
04Excellent field applicability

Uses

01Middle layer pavement for concrete roads and bridge pavement
02Water-tightness pavement
03Pavements to reduce reflective cracks

Composition

Cross Section	Properties
	Middle layer - High Elasticity Waterproof Asphalt
	Middle layer - High Elasticity Waterproof Asphalt Prevents moisture penetration and protects the lower concrete slab by applying a waterproof asphalt mixture of less than 1% Inhibition of reflective cracking from lower concrete by applying high-elasticity asphalt modifier
	Surface layer - Modified Asphalt
	Application of modified asphalt binder of PG 76-22 or higher Protects the upper part of the pavement layer by resisting the load of heavy vehicle roads Improved pavement commonality through plastic deformation and crack resistance
