About the Cover

The worst situation that asphalt concrete pavement can practice throughout its service life is the repetitions of heavy wheel loading, and ageing process accompanied by harsh environment. However, the initiation of microcracks which indicate the start of pavement deterioration can be controled by enhancing the healing properties of asphalt binder. Supporting the healing property of asphalt binder by implementation of additives exhibit a resilient remeady for pavement distress. In the present investigation, the influence of polemeric additives (LDPE, and Crumb Rubber) on the resilient, and healing behavior of asphalt concrete mixtures was assessed. Slab samples were prepared and compacted by roller. Beam specimens were extruded from roller compacted slab samples and tested for fatigue under constant strain level using four point bending beam technique. The test was terminated when the stiffness reaches 50 % of its original values.
