COMPACTIBILITY OF ASPHALT PAVING MIXTURES AND RELATION TO PERMANENT DEFORMATION

Most current specifications require asphalt paving mixtures to be compacted to a specified density, which in general is equivalent to a certain percentage of laboratory compaction. The application of such a density requirement in conditions of high in-service pavement temperatures and heavy traffic loading has resulted in many cases in excessive permanent deformation within the asphalt layers. For this reason, research has been carried out with the objective of studying the compactive effort. The effect of mix variables such as filler content, binder content, and type of binder is included in the experimental program. Marshall specimens for each mix were subjected to compaction levels of from 5 to 100 blows on each face. Each specimen was then tested for creep at 40 deg C under a controlled constant stress (0.1 MPa) for 30-min load duration. Based on the experimental data and using linear regression analysis, relation between compactibility and stiffness characteristics for each mix is established that is important in controlling permanent deformation distresses.
