According to the investigation and inspection on asphalt pavement corrugation section above semi-rigid base in Gan-Ding Highway,the causes of asphalt pavement corrugation are analyzed based on non-loading cracks of base,hydrodynamic pressure and dynamic effect of vehicles.

The possible reasons of non-loaded cracks of high-strength concrete structures were discussed in this paper.

slab s cracks while pointing out the important meaning on research slab s non-loaded cracks.

This thesis investigated and researched on non-loaded crack, especially those caused by thermal-shrink, and analyzed the thermal-shrink stress of beam, slab and continuous-wall, found that according data of civil and overseas offered thermal-shrink calculating formula without considering effect of factors, such as.

Application of synchronous chip seal to reducing the nonreflective cracks for semi-rigid pavement

According to non-loaded cracks produced in asphalt concrete pavement with semi-rigid base reasons caused the transverse cracks in lime-flyash stabilized broken stone base are analyzed;at the same time corresponding measures are proposed for mix proportion design to strengthen construction control and reduce non-loaded reflection cracks for asphalt concrete pavement with semi-rigid base.

Analysis of non-loaded fatigue crack early in asphalt pavement and the settlement;
