Theoretical shear strength
WebbCurves were developed for aggregate-only density, GSI, and shear strength. Aggregate-only density is the density of the aggregate mass in the specimen. A typical set of curves is shown in Figure 2. Asphalt content at maximum aggregate-only density, a GSI of 1.0, and a minimum shear strength of 310 kPa was determined from the graphs. The theoretical yield strength of a perfect crystal is much higher than the observed stress at the initiation of plastic flow. That experimentally measured yield strength is significantly lower than the expected theoretical value can be explained by the presence of dislocations and defects in the materials. Indeed, whiskers with perfect single crystal structure and defect-free surfaces have been shown to dem…
