Abstract:

Longitudinal cracking in pavements due to drying shrinkage of high-plastic subgrade soils has been a major ; problem in Oklahoma. Annual maintenance to seal and repair these distress problems costs significant amount of ; money to the state. The longitudinal cracks occur usually within the so-called edge moisture variation distance, ; where the climate plays a significant role in terms of changes in moisture content. The current study investigated ; the longitudinal drying shrinkage problems in pavement subgrade soils at three sites in Oklahoma. Two of the ; sites located in Norman and Oklahoma City are bike trails and the third site is along the Interstate Highway I-35 in ; Ardmore. The soil specimens collected from these sites were tested for the basic index properties as well as ; suction and unsaturated diffusivity measurements. Various ranges of the test results have been implemented in a ; suction profile and tensile stress prediction models for evaluating the typical suction changes and the ; corresponding tensile stresses in subgrade soils
