2016-12-18  base is an important layer in both flexible and rigid pavements. It mainly acts as a structural layer helping to spread the wheel loads so that the subgrade is not overstressed. It also plays a useful role as a separation layer between the base and the subgrade and provides a good working platform on which the other paving

Geostatistical analysis of intelligent compaction

2018-5-1  The aggregate base layer was compacted by a single drum vibratory roller with the same IC system, CAT CS54. To explore any correlation between the aggregate base layer compaction and the asphalt layer compaction, the geostatistical analysis was performed on the CMV of both the aggregate base layer and the asphalt layers.

The relationship from Eq. 4, again for a material whose minus No. 4 fraction has a maximum laboratory density of 135 pcf and whose plus No. 4 fraction has a specific gravity of 2.64, is seen graphically as Curve B in Figure 1. It is seen that regardless of how little coarse aggregate is present, its presence has the effect of lowering the
