Monograph

These 13 papers are concerned with geology and the properties of earth materials. Three of the papers discuss topics on rural low-volume roads issues, including objective distress measures for evaluating unpaved road condition, estimating roughness of unpaved roads, and assessing heavy traffic impacts on gravel roads. The other 10 papers address the following topics: the three-point imaging test for AASHTO soil classification; the effect of exopolymers on the liquid limit of clays; evaluating road substructure drainage systems using structural asset management; the matric suction prediction model in the AASHTO Mechanistic-Empirical Pavement Design Guide; soil suction; subgrade resilient modulus; and double draining layer flexible pavements.
