Abstract

This investigation was developed to examine response of a field-mixed asphalt-treated granular base material to 100,000 repetitions of a load whose magnitude was determined by a failure criterion proposed by Hoover (1970), and Fish and Hoover (1969). Axial strain and load at the point of maximum volume of a specimen during a conventional triaxial test appear to produce a "proportional limit," indicating that failure may have started. Axial stress at this point was applied in the repetitive loading triaxial test at the same confining pressure, during which axial strain and pore pressure continuously increased and specimen volume decreased in each of three series of tests. Post repetitive specimen condition, determined by retesting in the conventional manner indicated that none of the specimens had "failed" during repetitive loading. Results of this series of tests indicate a further potential feasibility of the use of minimum volume failure criteria for thickness design of a granular base material.
