How to Determine the Aggregate Crushing Strength Value

2018-4-26  Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.

2021-9-7  The aggregate crushing strength for various types of surface course of pavements should be high enough to withstand the high wheel load, including the steel tires of loaded bullock-carts. However, low strength aggregates having lesser crushing strength are used in base and sub-base courses of pavements. IRC have specified aggregates crushing ...
