TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2053 includes 9 papers that explore frost and thaw depth predictors for variable load restrictions, climate change impact on low-volume roads, sensor technology for spring load restrictions, fly ash with calcium chloride for stabilization of base and subgrade courses, and time domain reflectometry and micromechanics for determining moisture content of soil layers. This issue of the TRR also examines field and laboratory suction measurements of expansive clays, computerized cone penetration test for soil classification, correlations between PENCEL pressuremeter, cone penetrometer, and dilatometer parameters, and correlation between resilient modulus and plastic deformation for cohesive subgrade soil under repeated loading.
