Application of Vibration Test Methods in Cement-Treated Aggregate

The disease causes by the application of cement-stabilized macadam in our country first-class highway mainly performance as serious shrinkage fracture and other destructions like decreased capacity etc.This mainly related to test, design and other methods of the cement stabilized macadam. In the cement stabilization granular base construction,according to the standard job practice, uses the inorganic binding stable material compaction test to perform the standard compaction test. Doing compactness test at the scene, always present that the dry weight density is bigger than the maximum value result made by compaction test, result made by compactness test can more than 100%.The compaction principle of vibration compaction test is through pressure exciting force over the compacted materials,forced the downing of solid materials have a "resonance", In this state, the small particles aggregate can filling the gap between the large particles aggregate, to achieve the dense state. And during this process do not need too much water as lubricant. Therefore the vibration compaction test definite intensity result tallies with the scene reality. To imitation effects of roller compacted to improve the performance of cement stabilized gravel, the use of vibration method designed cement stabilized gravel is very necessary and timely.
