A parametric study to improve suitability of micro-deval test to assess unbound base course aggregates

open access: yesConstruction 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.

Testing the abrasion resistance of aggregates including by-products by using Micro Deval apparatus with different standard test methods

open access: yesConstruction 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 ...

Review of the relationship between aggregates geology and Los Angeles and micro-Deval tests [PDF]

open access: yesBulletin 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 ...

Comparison of Different-Energy-Level Abrasion in Los Angeles and Micro-Deval Apparatuses Using Mass Loss and Rounding of Sediment Particles

open access: yesApplied 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.

Long-term abrasion of rocks assessed by micro-Deval tests and estimation of the abrasion process of rock types based on strength parameters

open access: yesEngineering Geology, 2021
Abstract Testing long-term properties of aggregates requires time consuming laboratory tests. Alternatively, mathematical models can also be used to describe the abrasion process of aggregates. The paper uses another approach it links long-term abrasion to rock mechanical properties to facilitate a quick assessment of long term behavior of aggregates.

Analysis of coarse aggregate performance based on the modified Micro Deval abrasion test

open access: yesInternational 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 ...

Strength and abrasive properties of andesite: relationships between strength parameters measured on cylindrical test specimens and micro-Deval values—a tool for durability assessment [PDF]

open access: yesBulletin of Engineering Geology and the Environment, 2020
AbstractAggregates are necessary materials for the construction industry. Owing to their favourable properties, andesites are frequently used rock materials; hence, the investigation of their mechanical and aggregate properties has great significance. This paper introduces the analyses of 13 Hungarian andesite lithotypes.
