Increase in pavement distress has prompted the study and investigation of the use of polymers as asphalt cement modifiers. It was observed that rubber-related polymers are most suitable and they improved on the resilience, toughness, and reduced temperature susceptibility of the asphalt. Development of cracks, rutting and potholes were reduced, and water-proofing effect on the pavement was improved. Compatibility of asphalt mix, a major factor in the determination of extent of modification was enhanced by incorporation of catalysts, and application of mechanical method.
