The glacial gravel has high strength but couldn t be compacted easily;the filling materials made of glacial gravels in Jiangpinghe CFRD are compacted by impulsive vibro-roller,the compacted lift reaches 120 cm and the compactness is greatly improved;so the consturction progress of the dam is quickened and the cost is cut down.

Combining the practical project,engineers adopt some methods to treat airport foundation,such as high vacuum dewatering method,dynamic compaction method,bedding course method,and impactive rolling method.

Strain field analysis of weld with trailing impact rolling to control residual stress and distortion and prevent hot cracking;

Effect analysis of impact rolling in collapsible loess foundation treatment;

Mechanical behaviors of cement concrete pavement structure under impact rolling load;

According to requirements on non-suspending air service impaction and grind construction scheme is presented.

According to the geological conditions of runway system in Pudong Airport,testing proposal of "well point dewatering +Cushion+impaction and grind" was put forward and was monitored and detected during the testing procedure.

The application of impact compaction in roadbed construction

So as to a mass of experiment investigation and impact compaction,prominence increases the freeway subgrade impact density, strength and bears the weight of power, speeds up the freeway subgrade subside and reduces the freeway subgrade subside of the after work.

Plastic zone of pavement base increases gradually with the increasing times of impact compaction.
