This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test

The limits for impact value vary depending on the type of aggregate and its intended use. Here are some commonly used limits as per ASTM C131 and BS 812: Part 112: For base course and wearing course aggregates. Maximum impact value: 30%. Minimum impact value for heavy-duty concrete pavements: 20%.

Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.

crushes the aggregate to a degree which is dependent on the aggregate's crushing resistance. This degree is assessed by a sieving test on the crushed specimen and is taken as the Aggregate Crushing Value. 7.7.1.4 Sampling. The sample used for this test shall be taken in accordance with Chapter 2. 7.7.1.5 Equipment

The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = (Weight B / Weight A) × 100. Where: Weight A is the weight of the surface-dry sample. Weight B is the weight of the fraction passing the appropriate ...

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. ... 3.4.10 Aggregate Impact Value. The …
