| 摘 要： | 文章利用正交试验方法,分析水灰比、砂率、级配对碾压混凝土路面干缩系数及温缩系数的影响。结果表明：砂率对干缩和温缩系数的影响最为显著,水灰比对干缩系数的影响也较显著,但对温缩系数的影响不显著;级配对干缩系数和温缩系数的影响不太显著。

| Abstract: | By using the orthogonal test method,the article studies the effect of water cement ratio,sand ratio,and different gradation on shrinkage coefficient and temperature shrinkage coefficient of the roller compacted concrete pave-ment.The results show that sand ratio has the most significant effect;water ce-ment ratio on the coefficient of shrinkage effects is more obvious than it is on the temperature shrinkage coefficient;the effect of gradation is not significant on both coefficients. |
