Ballasted Railways in Senegal Characterization of Bandia

2019-8-16  The hardness of Basalt from the Diack quarries (Ngoundiane, Thiès Region) is 17.11. The Diack Basalt gives also good physical and mechanical characteristics (cleanliness, absorption, density, Deval and Los Angeles). For Senegalese public works, Diack Basalt is a good material for railway ballast.

Evaluation of the Strength of Railway Ballast Using

2016-1-23  Ballast degradation is one of the main sources of railway problems in which the ballast aggregates are gradually degraded due to the abrasion of the sharp corners of the angular particles and splitting each individual particle into two or several small pieces under loading.

Railway Ballast Function Of Stones In Railway Track

2020-6-4  Ballast is a common trackbed structure in the railway transport system, which is used to support track sleepers. A layer of crushed stones will be laid on the roadbed before the tracks are laid, which will then be compacted. Then sleepers and tracks will be laid. Distribute the pressure of the sleepers to the roadbed

STATE-OF-THE-ART DESIGN ASPECTS OF Railway

2012-6-26  Ballast is a free-draining granular material used as a load-bearing material, which forms the largest component of a rail track by weight and volume. Ballast materials usually include dolomite, rheolite, gneiss, basalt, granite and quartzite (Raymond, 1979). It is composed of medium to coarse gravel sized aggregates (10 60 mm) with a smaller percentage of cobble-sized particles. North American Railway systems use typical ballast sizes ranging from 4.76 mm to 51 mm. Australian Railways (AS 2758.7, 1996; TS 3402, 2001) uses ballast sizes varying from 13.2 mm to 63 mm. Good quality ballast should possess angular particles, have a high specific gravity, a high shear strength, a high toughness and hardness, a high resistance to weathering, a rough surface, and a minimum of hairline cracks (Indraratna et al, 1998). The main functions of ballast
