Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.
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.

Abstract. This specification covers qualitycontrolled graded aggregates that when hauled to and properly spread and compacted on a prepared grade to appropriate density standards may be expected to provide adequate stability and load support for use as highway or airport bases or subbases.
Oct 09 2018nbsp018332However it can be explain as the aggregate crushing value which is defined as a ratio of the weight of fines passing the specified sieve to the total weight of the sample expressed as a percentage. The value is usually recorded up to the first.
loss’. Rock materials with Aggregate Abrasion Values below 30 percent are regarded as strong while those above 35 percent would normally be regarded as too weak for use in road surface . 3.2. Aggregate Crushing Value (ACV) Determination . The Aggregate Crushing Value is a value which indicates
Jul 16 2014nbsp018332Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates the aggregate crushing value and aggregate impact values are numerically similar within close limits.

Apr 08 2017nbsp018332The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.
Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing degradation and disintegration in order to produce a high quality HMA Figure 1 L.A. abrasion testing equipment.
