Mixed With Expansive Agent And Fiber Cement Stabilized Gravel Crack Resistance

Based on the shrinkage analysis of cement-stabilized aggregate mixture , the performance of cement-stabilized aggregate mixtures with expansion agent or fibre .compared with that without admixtures, such as mechanical property .shrinkage , anti-freeze and durability are studied.The evaluation methods for anti-cracking performance , basing on split modulus, are put forward through tests .Anti-cracking performances of three kinds of cement-stabilized aggregate mixtures are evaluated by this way .The paper studied on the rules of shrinkage and explained the benefit of expansion and fibre to anti-cracking performance.And then through paving test road in Kaifeng , the paper studied on anti-cracking performances of cement-stabilized aggregate mixture. These methods are benefit to control of construction quality.
