Abstract:

A laboratory model study of an anchored pavement is described. The objective of the study was to investigate construction problems and development of specifications for a full-scale test. Also, the model tests could be and have been used to verify the analytical model. The model pavement involved 1/20-scale anchored and conventional slabs of similar dimensions and made of aluminum, a subgrade of known properties, a container tank for the whole setup, and loading and measuring equipment. In addition, one set of tests was performed by using the anchored slab in such a way that it is not in contact with the subgrade. The open space (void) between the slab and the subgrade simulates the worst conditions of no support caused by high moisture in the subgrade due to thaw or other actions. The model test results were compared with results from finite-element analysis. The investigations confirm that an anchored slab offers distinct advantages over a conventional slab; for example, the deflections are lower and uniform compared with those from a conventional slab, and stresses in the soil are reduced and distributed more widely by rigid anchors. The ANSYS computer program can analyze such a soil-structure system and incorporate the environmental and mechanical effects. (Author)
