Aggregate Crushing Value Test -Determine Aggregate

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Los Angeles Abrasion Test Procedure, Method, Significance

The test also will determine the quality of the aggregate. The L.A. Abrasion test is widely used as an indicator of the relative quality or competence of mineral aggregates. Standard Test Methods are: AASHTO T 96 and ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine

An investigation into the influence of size on the mechanical

Tests have been carried out according to British Standard BS 812-1975 on non-standard and standard size aggregates to study the influence of aggregate size on mechanical properties. Dolerite, granite, limestone aggregates of different sizes have been tested. No basic relations have been found between elongation index, IE, and flakiness index, IF, and the different aggregate sizes. Aggregate

What is the significance of ten percent fines value in

This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular sub-base is subjected to repeated loadings from truck types. The stress level at the contact points of aggregate particles is quite high.

their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. 3.

7 Lab Tests on Aggregate to Check Quality for Use in Road

The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.
