Strength of Virginia's 12-inch and 34-inch Asphalt Surface Mixtures
Report No: 93-R9
Published in 1993
About the report:
This study was undertaken to measure what, if any, differences exist in strength between mixtures made with 3/4-in (19-mm) maximum size aggregate and those made with 1/2-in (13-mm) maximum size aggregate. In order to make a comparison, a definition of equivalent gradation was necessary. This definition used a constant slope, n, of the log percent passing versus the log sieve size. Tests included gyratory shear, creep, resilient modulus, indirect tensile strength, and failure strain. It was concluded that with the gradations and aggregates studied, the type of aggregate is a more significant source of difference in strength than either aggregate maximum size or the gradation used.
