由于新河高速公路路基具有填土含水量偏高、路用性能较差的特点,导致路基弯沉值偏大。针对上述问题,提出了碎石土填筑路床处治技术,完成了碎石土室内物理力学性质试验和现场试验段的铺筑,现场弯沉测试结果表明,碎石土填筑路床大大提高了路基的整体强度。
As the embankment of Xinhe Expressway has the characteristics of high filling water content and poor road performance, the deflection value of subgrade is too large. In view of the above problems, we put forward the gravel-soil filling roadbed treatment technology, completed the physical and mechanical properties test of macadam and indoor pavement, and the field deflection test results show that the crushed stone roadbed is greatly improved The overall strength of the roadbed.
