DEFORMATION BEHAVIOUR OF SUBGRADE SOIL AND RUTTING IN A FLEXIBLE PAVEMENT
The paper discusses the stress conditions that need to be simulated in laboratory testing of subgrade soils so that pavement behaviour may be assessed accurately. Details are given of repeated loading triaxial tests on the subgrade soil of the Orissa trunk road at in situ moisture content and density to determine the plastic stress-strain characteristics of the soil. The rut depth was calculated by using the layer-strain approach, taking into account the lateral swelling of the pavement on either side of the wheel path. For the covering abstract see TRIS 450963.
