Improved Test Methods for Specific Gravity and Absorption of Coarse and Fine Aggregate

"TRB's National Cooperative Highway Research Program (NCHRP) Report 805: Improved Test Methods for Specific Gravity and Absorption of Coarse and Fine Aggregate develops test methods for determining the specific gravity and absorption of coarse and fine aggregates. This test is designed to improve the accuracy, precision, ease of use, and time required for conditioning and testing as compared to the current American Association of State Highway and Transportation Officials (AASHTO) T 84 and T 85 methods." -- Publisher's description.
