Furthermore, it can be derived that the required shear strength values for the asphalt mixture used in the wearing course, binder course, and base course are, respectively, 0.682, 0.717, and 0.545 MPa. If the mixture cannot meet the requirement for shear strength, the pavement will suffer excess rutting.

How to Determine the Aggregate Crushing Strength

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.
