摘要:
为研究破碎砾石水泥稳定基层的收缩性能以提高其适用性,通过逐级填充法确定配合比,探讨其抗冲刷性能和收缩性能.研究结果表明:增加水泥剂量可有效提高抗冲刷性能,干缩主要发生在早期,且失水率和干缩系数均随时间的延长而增大.2种破碎砾石水泥稳定基层(悬浮密实型和骨架密实型)的性能存在差异.对悬浮密实型,粗细集料比越大,7 d无侧限抗压强度越大;级配越粗,抗冲刷性能越强.对骨架密实型,在细集料含量不变的情况下,提高16 mm以上粗集料的含量可增强7 d无侧限抗压强度和抗冲刷性能.悬浮密实型的失水率、干缩系数、干缩应变和温缩系数均大于骨架密实型,且干缩应变变化率要高于失水率变化率.悬浮密实型的收缩性能整体上弱于骨架密实型.
Abstract:
In order to study the shrinkage performance of crushed gravel cement stabilized base and improve its applicability, the synthetic gradation is determined by the step-by-step filling method, and the erosion resistance and shrinkage properties are discussed. The research results show that with the increase of the cement dosage, the erosion resistance is improved, and the dry shrinkage mainly occurs in the early stage, both the water loss rate and the dry shrinkage coefficient increase with time.The performance of two kinds of crushed gravel cement stabilized base(the suspended dense structure and skeleton dense structure)is different.For the suspended dense structure, the greater the ratio of coarse and fine aggregate, the higher the seven-day unconfined compressive strength, and the coarser the gradation, the stronger the erosion resistance. For the skeleton dense structure, without increasing the content of fine aggregate, increasing the content of coarse aggregate above 16 mm can increase the 7 d unconfined compressive strength and the erosion resistance.The water loss rate, dry shrinkage coefficient, dry shrinkage strain and temperature shrinkage coefficient of the suspended dense structure are greater than those of the skeleton dense structure,and the change rate of the dry shrinkage strain is higher than that of the water loss rate.The shrinkage characteristics of the suspended dense structure are generally weaker than those of the skeleton dense structure.
