【摘要】 为提高半刚性基层的抗裂能力,根据抗裂能力最佳、强度满足要求的原则,分别用静压法及振动法进行了水泥稳定碎石混合料级配和配比的优化,并对优化结果进行了对比分析。试验结果表明,现场经振动压实的水泥稳定碎石混合料强度、抗裂特性与室内振动成型的混合料特性更趋于一致,用振动法优化的级配配比可显著提高半刚性基层的抗裂能力。更多还原

【Abstract】 In order to improve the anti-cracking performance of semi-rigid roadbase,the cement stabilized macadam’s mix ratio was optimized with static pressure method and vibratory method respectively which based on the principles that anti-cracking performance is optimal and strength value meets the engineering demand.Test results indicate that it is more reasonable that using vibratory method experimental results to control construction quality, and using vibratory design method result can improve the anti-cracking performance of semi-rigid roadbase obviously.(8 tabs,) 7 figs,6 refs.更多还原
