This document describes the procedure for determining the aggregate crushing value (ACV) of aggregate materials. The ACV test involves crushing a sample of aggregate between 9.5mm and 13.2mm under a gradually applied 400kN load. The percentage of material crushed finer than 2.36mm is calculated and reported as the ACV. The test can be performed dry or after soaking …

7.7 Aggregate Crushing Value and 10% Fines Value 7.7.1 Aggregate Crushing Value (ACV) 7.7.1.1 Introduction. One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An ...

Productivity and efficiency play a vital role in determining the overall value of the investment. Factors such as the crusher's throughput capacity, reduction ratio, and the quality of the final product should be considered. A more efficient crusher can help reduce operational costs and increase productivity, resulting in improved profitability. 5.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value?
