ROADS WITH PS-HARDFOAM TESTED FOR SETTLEMENT

WEGEN MET PS-HARDSCHUIM OP ZETTING ONDERZOCHT

Light pavement constructions with PS-hardfoam (expanded polystyrene) have been used in the Netherlands for some years in situations with weak subsoils in order to prevent settlement. Sufficient practical experience has been gained with these constructions by now to verify the Dutch design principles on the basis of measurement results. On five locations, where eleven different constructions with PS-hardfoam have been applied, deflection measurements have been carried out, the results of which have been presented as deflection curves. These have been used to calculate back the dynamic stiffness moduli of the different layers in the constructions with the aid of the "CIRCLY" computer program. For this purpose the constructions have been modelled as linear elastic multi-layer models. The interpretations of the measurements have been compared to measurements made on traditional pavement constructions. Next, comparisons have been made with the design principles for light pavement constructions with PS-hardfoam. From this it appears, that the principles assumed for the dynamic stiffness modules of PS-hardfoam are safe. (TRRL)
