AIM 1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.
The aggregate crushing value is a crucial essential index to evaluate a material's crushing resistance based on current specifications for road base construction. In this study, the addition of brick or mortar reduced the aggregate crushing value, causing difficulties in reusing CDW for high-quality road bases.
The aggregate crushing value test is conducted on coarse aggregates to determine their resistance to crushing under gradually applied compressive load. It is expressed as a percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. The …
