Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using three ...

Experimental Study to Reinforce The Weak Subgrade Soil For Low-Volume Roads by Coir Geotextile Mats

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2018
The construction and maintenance of pavement over the weak subgrade soil become the challenging task to the pavement engineering. One of the major reasons of subgrade failure of pavement is weak subgrade. The weak subgrade soil noticed a Black Cotton (BC)

Rail Track Maintenance Planning: An Assessment Model [PDF]

, 2000
In Australia, railway track maintenance costs comprise between 25-35 percent of total freight train operating costs. Track maintenance planning models have been shown to reduce maintenance costs by 5 to 10 percent though improved planning.

Study on the Deformation Characteristics of Railway Subgrade Structures Induced by Groundwater Level Changes

Advances in Civil Engineering
The groundwater extraction will lead to a drop in water level, causing a change in the distribution of additional stress in the strata. This phenomenon leads to uneven settlement of the railway subgrade.
