  • DETERMINING PERCENT OF FRACTURED PARTICLES IN COARSE

    Specifications contain requirements for percentage of crushed aggregate particles, with the purpose of maximizing shear strength in either bound or unbound aggregate mixtures. This method can be used in determining the acceptability of coarse, dense- graded, and open-graded aggregates with respect to such requirements. This procedure is used primarily for hot mix asphalt aggregates. SUMMARY OF
