本文以某一级公路为例,就水泥稳定碎石路面基层的设计及应用首先从无机结合料稳定材料配合比设计程序,确定级配及波动范围进行了理论探讨与计算;然后初选水泥用量并通过7天无侧限抗压强度试验及道路建设实际情况,确定了最终的生产水泥掺量为4.5%。通过现场施工结果可以看出,该水泥稳定碎石路面基层配合比设计效果较好。最后就生产过程施工中级配波动范围控制混合料级配提出了一定的建议。
In this paper, a highway as an example, the design and application of cement stabilized gravel road base first from the binder material with inorganic binder material design process to determine the grading and the scope of fluctuations in the theoretical discussion and calculation; then the primary cement dosage And through the 7 days unconfined compressive strength test and the actual situation of road construction, it was confirmed that the final production cement content was 4.5%. According to the result of on-site construction, it can be seen that the mix design of the cement stabilized gravel pavement is better. Finally, we put forward some suggestions on grading of medium-level fluctuation range control mixture in the production process.
