Research about Different Molding Methods’ Effect on the Resistance against Frost and Shrinkage of Cement Stabilized Gravel

Abstract:

Through the test research of the two different molding methods of vibration and static pressure, including the analysis of traditional heavy compaction and the new vibration compaction, we could see that the result of the vibration could satisfied the field construction. Analysis of mechanical property was 7d unconfined compressive strength, at the same dose of cement, the strength of vibration was higher than the static pressure method’s and it was more rational and effective for the field control of the construction. Evaluation of water stability was up to the 28d and 5 times freezing-thawing tests, and the resistance ability against frost of vibration was better than the static pressure method. So adopting the vibration method could improve the resistance performance against frost of the road in northeast region of freezing-thawing in spring. From the 7d dry shrinkage test we got that the adopting the vibration method the resistance performance of dry shrinkage was much better and could improve the resistance against shrinkage of the road.
