Standard of Crushing Value of Coarse Aggregates for Permeable
Jan 20, 2020So, the crushing value of coarse aggregate is very important for the durability of PA mixture [ 1 3 ]. Yan et al. proposed that the requirement for the crushing value should be no more than 20% [ 4 ]. Huang proposed that the crushing value of coarse aggregates for OGFC mixture should be no more than 25% [ 5 ].

Aggregate Crushing Value Test The Constructor
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. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.

Aggregate Crushing Value SignificanceTest Procedure
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 = (W2/W1) x 100 Lab Report
