Experimental Research about Shrinkage of Cement Stabilized Gravel Base

Abstract

The semi-rigid base asphalt pavement has become the main form of high grade Highway pavement structure in China. But with changes in temperature, humidity and amount of traffic, serious cracking problems also exist in this pavement, affecting pavement performance. Analyses crack type of asphalt pavement and its causes, for serious reflection crack problem of semi-rigid base asphalt pavement, by on different structure type and different cement dose cement stabilized gravel mixture for indoor dry shrink and temperature shrink test research analyse variation law of its dry shrink strain, and dry shrink coefficient, and temperature shrink strain, and temperature shrink coefficient, ect. and provides basis to improve semi-rigid base asphalt pavement anti-crack performance.
