Effects of Field Compaction Method on Water Permeability and Performance of Asphalt Concrete Pavements
This paper presents the results of field studies of hot mix asphalt pavements compaction using conventional compaction technologies (train of vibratory steel drum, pneumatic tired roller) and the Asphalt Multi-Integrated Roller (AMIR) to examine the effects of different compaction methods on the water permeability of asphalt concrete pavements as a surrogate measure of durability and eventual long-term performance. Nine different pavement construction projects were used in this paper where laboratory and field properties of pavements compacted using conventional and AMIR compaction were measured and evaluated. Field measurements of water permeability showed higher mean value and higher variation of the permeability coefficient for conventional compaction than the AMIR-compacted pavements, even though the air voids and relative compaction were almost the same. Compared to the conventional compaction, statistical analysis showed that AMIR compaction reduced water permeability of compacted surfaces on stiff bases (such as an overlay on top of a milled asphalt concrete pavement) and also reduced the rate of permeability increase due to increase in air voids.
