The Texas Department of Transportation has experienced problems with inconsistent performance of the coarse aggregate fraction of hotmix asphalt pavements. This project was initiated to address problems associated with variations in hotmix coarse aggregate quality. More specifically, the researchers wanted to identify simple tests that can be performed at the aggregate quarries to assess the du...

In the mixing process between asphalt and aggregate, absorption of by aggregate occurs through pores aggregate. The volume not absorbed can be defined as effective content which determines percentage airspaces in compacted mix. proportion voids formed mixture contributes to durability against temperature climate conditions. This study aims examine effect film thickness on mixture. Based analysi...
