The effect of unsaturated soils on pavement performance is examined through a case history involving a narrow pavement constructed on at-grade section. The pavement function was for bicycle and pedestrian traffic in a recreational project in Oklahoma City, Oklahoma. The pavement section consisted of asphalt concrete surface course underlain by aggregate base on a prepared subgrade. Following co…
The study of matrix and total suction versus depth is important in the analysis and design of slabs on grade such as light structure building slabs and highway pavements. This paper quantifies the seasonal moisture profiles with depth in two typical expansive Oklahoma clays. These soils can be characterized as being medium to highly plastic, blocky structured, with a medium stiff consistency, s…
