Aggregate by conducting some tests such as particle size distribution test, density test, water absorption test, aggregate crushing value test, compaction test, and penetration test. the second objective is the strength performance of the rca compared to the nca by using the california bearing ratio (cbr) method. 3. road base.

Aggregate crushing value (w2 x 100) (w1w) w2 weight of fraction passing through the appropriate sieve w1w weight of surface dry sample. the mean of two result to nearest whole number is the aggregate crushing value. result the aggregate crushing value of the given sample aggregate crushing values for roads and pavement construction.

Aggregate is strong as the crushing fraction is low. thus, this test also uses to access the suitability of aggregates for various type of construction work due the crushing strength of the aggregate. the results of acv was obtained by the mean of the crushing value in the two tests is reported as the aggregate crushing value. the limits of acv.

Calculation of aggregate crushing value. the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the is sieve 2.36mm and the weight of the dried aggregate sample. at least three samples should be tested from the same batch and average value to get accurate results. the crushing value of aggregate (w2w1) x 100. lab report.
