Abstract

This paper presents data from a series of investigations performed with peat soil to determine resilient deformation under dynamic load, which has great influence on the design of connections between concrete plates that are used as pavement for rural roads. The experiments were performed both in situ and under laboratory conditions using a concrete plate, size 3m by 1 m by 0.15m placed over peat. Other experiments were made with the concrete plate placed over the various thicknesses of sand fill above the surface of peat soil. Experiments were carried out under dynamic load. The laboratory experiments were conducted with a special apparatus designed and manufactured for the study. The dynamic load apparatus allowed changes in load, speed, and intensity of load. This paper describes the apparatus, which tests undisturbed peat soil samples having dimensions of 0.5m by 0.5m by 0.3m. The paper presents results of a field and laboratory study on undisturbed homogeneous and laminated samples of peat soil and fine sand under the plate. Based on the results of the field and laboratory experiments under dynamic load, an empirical equation is proposed for the resilient modulus of subgrade reaction related to peat soil properties under large concrete plates.

Dynamic Loading-Deformation Performance of Peat Soil under Large Concrete Plates
