The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
2024125· The aggregate crushing value for the surface course should be within 30% and for the base course, it should not exceed 45%. In a question asked about aggregate crushing value for cement concrete pavement but is not mention about surface or base course, so we assume it is asked about the base course as per given option.

Aggregate Crushing Value is the relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is an important test to be performed on aggregate.
1 Scope 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 sieve.
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value.

This paper presents an assessment of the Aggregate Impact Value (AIV) test, crucial for evaluating the strength and suitability of aggregates used in road construction. The AIV indicates the resistance of aggregates to crushing under …
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).
7.7.1.2 Scope. The particular purpose which an aggregate is meant to serve requires the aggregate to have a particular strength. This strength is usually stated in the specification. This test provides a method for measuring this strength. This method is not suitable for testing aggregates with a crushing value higher than 30, and in this case the ten percent fines value is …
