Low-density polyethylene (LDPE) has been used by many to modify asphalt cement and to improve the properties of bituminous mixes (hot-mix asphalt). In this investigation, reclaimed polyethylene (PE) obtained from LDPE carry bags was used to modify asphalt cement. The basic properties of modified binder and mixes containing such binders were studied and compared with those of asphalt cement. It was observed that the optimum requirement of PE is 2.5%. Marshall stability, resilient modulus, fatigue life, and moisture susceptibility of mixes were improved as a result of modification of asphalt cement by reclaimed polyethylene.
