Review of the relationship between aggregates geology and Los Angeles and micro-Deval tests [PDF]
Bulletin of Engineering Geology and the Environment, 2021 AbstractRock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering properties of these rocks vary due to the differences in the transformation process (e.g ...

Construction and Building Materials, 2017 Abstract Micro-deval test provides a measure of resistance and durability of aggregates submerged in water through the actions of aggregate particles and abrasion from steel balls. The presence of water in the test chamber provides a more realistic assessment of field conditions when compared with Los Angeles (LA) abrasion test.

Procedia Engineering, 2016 AbstractThroughout the life of the track, ballast grains wear as a result of both the trains passing over the track and the maintenance operations (tamping). The morphology of the grains is changed: they lose angularity and fine particles are produced, causing a gradual loss of track performance. Eventually ballast renewal becomes necessary.

The effect of particle shape on the deformation and stress reduction of a gravel soil due to wetting [PDF]
Scientific Reports, 2021 This paper investigates the effect of particle shape on the stress reduction and collapse deformation of gravelly soil using a medium-scale direct shear test apparatus under different relative densities, normal stress, and shear stress levels.

Applied Sciences, 2023 During the routing of coarse particles in sedimentary environments, the particles are subjected to abrasion, leading to mass loss and changes in the particles’ morphology. The particles become more spherical, rounded, and smooth.

Analysis of coarse aggregate performance based on the modified Micro Deval abrasion test
International Journal of Pavement Research and Technology, 2018 Abstract The anti-abrasion property of aggregate significantly affects the performance of the pavement. In this research, the quartzite and gneiss which were produced in Lincheng County, Xingtai City, Hebei Province were selected as test samples. According to the American Society for Testing and Materials standard, the Micro-Deval abrasion test was ...

Construction and Building Materials, 2016 Abstract Structural and functional performance of a pavement is affected by aggregate properties; therefore, characterizing the aggregate properties is crucial. Series of tests are conducted on road construction aggregates, not only for selection of appropriate aggregate which meets related specifications, but also for estimation of the long-term ...

Transportes, 2021 The objective of this study was to evaluate, comparatively, the evolution of this degradation of three rock types, two granitoids and a microgabbro which, eventually, could be used as ballast, due to the proximity of the quarries to the design route of a
