Laboratory assessment of Alaska aggregates using Micro-Deval test

Frontiers of Structural and Civil Engineering, 2017
Aggregates suitable for use in asphalt concrete (AC) pavement construction must meet durability criteria. Thus, it is critical to select appropriate tests to properly characterize aggregate durability. In Alaska, durability tests currently being used for aggregates in AC pavement include Los Angeles (LA) abrasion test, sulfate soundness test and ...

Simulation on the Micro-Deval test for the aggregate wear properties measurement

Construction and Building Materials, 2018
Abstract In this study, a simulation on the Micro-Deval test was presented for the aggregate wear properties measurement. The performance parameters including wear resistance, density, elasticity and Poisson ratio of the five kind aggregates were obtained by tests on red sandstone, basalt, limestone, quartzite and gneiss.

Comparative Analysis of Idaho and Micro-Deval Aggregate Degradation Test Methods

Journal of Materials in Civil Engineering, 2014
AbstractIn the United States, several states have adopted the Micro-Deval test (MDT) method for evaluating degradation characteristics of aggregates used in road construction. This paper compares MDT aggregate degradation data to those obtained by the Idaho degradation test (IDT) method. Simple linear regression analyses were performed on the aggregate

Use of the Micro-Deval Test for Assessing Fine Aggregate Durability

Transportation Research Record, 2008
The Micro-Deval test was evaluated for its suitability in assessing the durability of fine aggregate from Virginia sources. Fine aggregates from 10 sources with known performance histories were tested with the Micro-Deval and several common aggregate quality methods. The Canadian Micro-Deval testing protocol for fine aggregates was followed.

Results of Micro-Deval Test for Coarse Aggregates from Virginia Sources

Transportation Research Record, 2008
Aggregate is the most widely used construction material, and a key aspect of aggregate quality is durability. In this study, the Micro-Deval test was studied to evaluate its suitability for assessing the durability of coarse aggregates from Virginia sources.

Canadian experience with the micro-Deval test for aggregates

Geological Society Engineering Geology Special Publication, 1998
Abstract Several aggregate test methods used in evaluating the mechanical strength and predicting the performance of aggregate have been in use since the 1930s. Today there is a need for precise tests that have a demonstrated correlation with field performance.

Ballast Wear: Insight from the Discrete Element Simulation of Tracks and Micro-Deval Tests

Civil-Comp Proceedings, 2016
cited By 0 ; International audience ; Throughout the life of a 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.

Mechanical Degradation of Aggregate by the Los Angeles-, the Micro-Deval- and the Nordic Test Methods

Rock Mechanics and Rock Engineering, 2011
The quality of aggregate used as buildings materials is defined by European Standard test methods. According to the agreement within the European Economic Area, each individual country decides test methods of current interest. Among the Nordic countries, the Los Angeles-, micro-Deval- and the Nordic test are the most common methods used to decide the ...

Predicting coarse aggregate performance using the micro-Deval test with strength and intrinsic particle property tests

, 2005
Numerous tests exist in the field of aggregate qualification which have little to no relation to field performance. Many aggregate sources have been restricted in their use due to non-conforming results from a test that has little relation to field performance.
