| 摘 要： | 研究了3种级配水泥稳定碎石的无侧限抗压强度、干燥收缩性能和不同龄期的温度收缩性能.由强度试验确定了性价比优良的水泥用量为4.0%.骨架密实型级配的干燥收缩和温度收缩性能优于另外2种级配.研究结果表明,不同级配对混合料性能具有较大影响;在满足基层强度要求的前提下,控制细集料用量可以明显改善基层抗收缩性能.

| Abstract: | This paper studied the unconfined compressive strength,the drying shrinkage performance and the temperature shrinkage performance at different ages of three gradations of cement stabilized macadam.Structural tests were analyzed to obtain a reasonable Cement content as 4.0% in a fine performance-price-ratio.Dry Shrinkage and Temperature-Shrinkage of the dense framework structure surpasses other two kinds of gradations.The research results indicated different graduations can affect the mixtures performance gr... |
