Abstract

The deterioration of flexible bound bituminous road layers in the form of creep deformation or fatigue cracking is caused by a number of contributing factors. Of primary importance are the influences of traffic volume, axle loading, mix volumetrics, material properties and environmental conditions. Whenever it is economically viable, polymer modified bitumens (PMBs) have become widely accepted as the binders of choice for the construction of highly durable asphalt mix road surfacings. Although extensive work exists in the literature on characterizing the rheology and chemistry of bitumens and PMBs, there remains the need to better understand the relationships between polymer type, chemistry, morphology and rheology of the resultant PMBs. In this study, 80/100pen grade bitumen was modified with up to 3% polymer content using two polymer types, namely linear low-density polyethylene (LLDPE) and polypropylene (PP)
