PAVEMENTS ON SWELLING AND SHRINKING CLAY SUBGRADES

This report presents the summary of theoretical, numerical and experimental investigations conducted to study the response of thin seal coated road pavement subjected to the seasonal subgrade volume change. The study was conducted in two stages. At first the effect of subgrade swelling on overlying pavement was studied. Later, it was extended to cover the effect of subgrade shrinkage. By combining these two, the work could produce a complete study on the mechanical behaviour of reactive soils subjected to the seasonal moisture variation, and the characteristic response of seal coated pavement to swelling and shrinking of subgrade upon wetting and drying. The report is written with the idea of providing necessary information to a road design engineer in order to understand the problem of distortion and cracking of pavements on reactive clay subgrades. The report includes a literature review and substantial description on the theoretical and numerical analysis, and the summary of results of the earlier conducted soil and pavement tests including the test set-ups and testing procedure are covered. It is expected that this information will be sufficient to develop a background for the analysis of response of pavement to subgrade volume change. (A)
