ABSTRACT

Highway engineers and administrators, and Construction industry made necessary improvements to asphalt pavements in the field of asphalt binders to bond asphalt layers, material selection, testing procedure, mix design method, material handling and through significant technological advancement in laying process. These actions and efforts created an assumption that newly constructed asphalt pavements which meet design objectives are structurally sound. However no significant improvements to the current compaction equipment and techniques were made to date. Pavement surface cracks which are induced by current compaction method ruins the above combined effort made by authorities and industry to achieve long lasting pavement. Improving compaction practice by introducing a new compactor; AMIR, can provide the quality of highway network with respect to authorities and industry expectation. This paper as well as earlier studies shows that AMIR roller applies low compaction pressure over a long contact duration which helps to provide efficient particle contact, expulsion of entrained air and keeps the initial stiffness response of the asphalt at low. Large contact area of the roller minimizes horizontal forces applied to the asphalt mat and provides a high degree of confinement during compaction. Elimination of roller induced cracking reduces surface permeability, increases density with less passes, improves resistance to fatigue damage and permits the full compaction energy to be applied to the pavement layer. This will enhance the existing necessary improvements made by transportation authorities in highway construction. Also, the end product is expected to reduce the required maintenance and rehabilitation costs which have been performed more frequent than expected.
