Sub-ballast layer made of bituminous material. Proc., 7th World Congress on High-speed Rail, China Railway Press, Beijing, 727-730Robinet, A. and A. Cuccaroni (2010) Sub-ballast Layer Made of Bituminous Material, Proceedings 7th World Congress on High Speed Rail, Beijing, December 2010, ...
This paper evaluates the design requirements and the impact of improving conventional high-speed ballasted tracks using a bituminous sub-ballast layer. It is divided into two main parts: first, the design requirements of the structural solutions with bituminous sub-ballast and its possible benefits ...
The absence of a subballast layer showed the highest suction values achieved over the year, mainly in the wet seasons, compared to the other scenarios. However, the fact that the subballast layer reduces the water evaporation in the subgrade during the dry seasons, keeping it wet over the ...
The functionalities, advantages and world-wide application cases of asphalt subballast layer were reviewed in this paper. The typical thickness design methods of asphalt subballast layer, as well as the key indices in mater...
The railway track's sub-ballast layer is important, but it is often neglected, leading to the contamination and blockage of voids, as well as track deformation and degradation. These issues occur when fouling materials infiltrate the subballast due to load-induced vibration. The purpose...
The most significant factors were found to be the grading, sorting and the water content of the material, the thickness of compacted layer and the procedure used for the compaction. The sorting of the material lead to inhomogeneous structure, which was found to be difficult in controlling the ...
New possibilities to reduce track costs on high-speed lines using a bituminous sub-ballast layer. Int. J. Pavement Eng. 2010, 11, 301-307. [CrossRef]P.F. Teixeira, A.L. Pita, P.A. Ferreira, "New possibilities to reduce track costs on high-speed lines using a bituminous sub-ballast...
This paper presents an investigation into the seepage hydraulics of a layer of subballast filter subjected to cyclic loading in a fully saturated environment. A multilayer mathematical approach was used to predict the time-dependent permeability of this filter, with a reduction in porosity as a func...
Sub-ballast layerCyclic triaxial testSoil loading resistanceWater content is one of the most important factors influencing the performance of earth structures. It is well known that the water content of sand has a significant effect on its shear strength and its resistance to cyclic loading. In ...
