2018年8月20日 The construction of a high-speed railway (HSR) in Southwest China is being hindered by a severe shortage of high-quality subgrade materials. However, red mudstone is widely distributed in the Sichuan Basin of China. The ability to use weathered red mudstone (WRM) to fill subgrade beds by controlling its critical stress and cumulative
2022年6月1日 The subgrade material was initially homogenized at target moisture content, then compacted to the required density inside the box. Because of the high percentage of water in the soil, a manual hammer with a quadratic base of 120 mm and a weight of 40 N was dropped from a height of 450 mm to deliver the compaction. The soil was

2020年9月1日 F R Silt = The value of FR index in the case of using silt as subgrade material (%) Similarly, the percent change in relative thickness of ballast fouled with fine particles is computed. Fig. 9 compares the filtration performance of sub-ballast course for subgrade types of clay and silt quantified by preceding defined indices. Evidently, the
2021年6月10日 CBR required for use as subgrade material (Perera et al., 2019). Using up to 40% reclaimed asphalt pavement (RAP) and basic oxy- gen furnace (BOF) aggregate in subgrade stabilisation satis es the
[PDF]2020年3月6日 The subgrade is that portion of the pavement system that is the layer of natural soil upon which the pavement or subbase is built. Subgrade soil provides support to the remainder of the pavement system. The quality of the subgrade will greatly influence the pavement design and the actual useful life of the pavement that is constructed.
2021年12月28日 The strength and deformability of subgrade fillers for heavy-haul railways are directly related to the quality and service life of railway engineering and the safety of train operation. Triaxial compression tests are performed to explore the effect of a binder material on the mechanical properties of a subgrade filler for the Bazhun heavy-haul railway, and

The quality of the subgrade will greatly influence the pavement design and the actual useful life of the pavement that is constructed.
Subgrade stability is a function of soil type, water content, degree of compaction, mineral content, and other characteristics. The desired goal in construction and maintenance is to secure high internal friction and shearing strength in coarse-grained materials and high cohesion in fine-grained soils.
