Permeability and Strength Characteristics of Graded Crushed Stone for Use in Rapid Runway Repair.

Abstract

The permeability and strength characteristics of six gradations of crushed limestone were evaluated in the laboratory to identify a gradation of crushed limestone that is stronger than the Tyndall gradation. Based on limited laboratory tests, pore pressure buildup did not seem to be a significant problem associated with the crushed limestone. The frictional strength criterion is not suitable for this crushed limestone because the friction angles obtained from undrained triaxial tests may not be valid within the applied range of confining pressures. With the assumption that strength at low confining pressure is more important than at high confining pressure, the cohesion criterion was selected for analyzing tests. Field traffic tests are needed to validate the assumption. (Author)
