ASTM D7428

Resistance of Fine Aggregate to Degradation by Abrasion in the Micro-Deval Apparatus

Applicability: ASTM D7428 is the standard test method for determining the resistance of fine aggregate to degradation by abrasion in the Micro-Deval apparatus. It is primarily applicable for evaluating the durability and toughness of aggregates used in pavement construction.

Purpose: The purpose of ASTM D7428 is to provide a standard test method for measuring the resistance of fine aggregate to degradation by abrasion in the Micro-Deval apparatus. The test evaluates durability in wet conditions, identifies weak materials, correlates with sulfate soundness, predict performance in pavements, and supports quality control/assurance.
