Analysis and Implementation of Modified Steelguard on Runway and Flexible Pavement

Abstract

Pavement maintenance is the part of highway engineering which deals with the function and performance of roads surface. Due to passes of time, higher traffic and distresses in the pavement, it functional performance is not achieved that’s why maintenance is required. Now a day, we use asphalt emulsion on larger scale for preventive maintenance, due its better results in materials binding capacity, available economically, easy in operation and many other reasons. Here we use an asphalt emulsion product which is named as Steel guard with Polymer modifiers like Acrylic copolymer or Polyvinyl acetate, for preservation and rehabilitation of flexible pavements, runways, taxiways and etc. It was intended to re establish minor pavement surface profile loss and expertly seal all asphalt top surfaces against quick deterioration from sun, natural conditions, tire friction or scraped area and gentle chemical attack.
