使用AHM800R-CH路基处理车(Schotterbettrein ie und maschine)整治路基翻浆冒泥是一种新型高效的方法,其最大特点是将挖掘出的旧道砟经过破碎后与新料混合后作为新的回填料。我国国内施工所取得的新料尚无法达到国外填料的要求标准,因此必须寻找适合我国的标准。经过研究级配曲线可以看出,《规范》的三号砂砾石级配与国外级配标准十分接近。因此,在取得新料级配的基础上,利用试算法与合成级配的原理,设计出破碎后的旧道砟级配及比例。经过承载力检测,能达到要求。
The use of the AHM800R-CH Schneidermiecht und Maschine is a new and highly efficient method of remediation of subgrade soils. The most prominent feature of this method is that the excavated old road 砟 is crushed and mixed with new material as a new backfill. China’s domestic construction of new materials still can not meet the requirements of foreign filler standards, it must find suitable for our standards. After studying the gradation curve, we can see that the No.3 gravel gradation is very close to that of foreign gradation. Therefore, on the basis of obtaining grading of new materials, the principle of trial calculation and synthesis grading is used to design the graded old road grading and proportion. After bearing capacity testing, to meet the requirements.
