STRENGTH COEFFICIENT OF MATERIALS

The study investigates the relationship of strength to thickness and type of material for six different construction materials; two bituminous paving materials, the same two aggregates without asphalt and two gravels typical of those normally used for base or subbase materials. Testing was conducted at a test site where each material was placed in thicknesses of 3 to 24 inches in three inch increments. In addition to normal laboratory and construction test procedures, plate bearing, Benkelman beam and Dynaflect tests were performed. Coefficients of strength were determined for the test materials and examples of design based upon these coefficients are shown.
