According to the application of the shock rolling crushing technology in the renovation of the old cement concrete pavement,the article uses the three-dimensional finite element method to study the bearing and deforming characters of the old pavement structure and earth foundation when 5-edge shock road roller is used to shock and crush.

The property of impact roller is excessive edge of compaction wheel which different from traditional road roller.

Because of the noncircular section wheel is used on impact roller, the state of working wheel is changing periodically from roll to impact.

For the with non circular section rolling wheel is adopted in impact roller, a new work method is made.

Compactness automatic detecting method of subgrade for intelligent impact roller;

Application of impact roller in roadbed compensatory compaction construction;

Application of impact roller to filling the stonework of subgrade;

The application of impact roller in the roadbed construction at the Wuying-Tangwanghe section of the Yijia highway;

Considering some weakness of the impact roller,we have suggest a new type of roller called the composite roller of impacting and vibration.

But balance of impact roller basically solved the Impact Roller\'s main problems.
