FOAMED CONCRETE IN ROAD CONSTRUCTIONS
In 1994 a C.R.O.W. study group started to make an inventory on the possibilities for the use of a foamed concrete as an improved subgrade or a road base. Foamed concrete is a cement bound material with a low density (400-1600 kg/m3--25-100 lb/ft3); and it has a structure consisting of a cement stone skeleton surrounded by a large number of finely distributed air pores. The study group published a guideline for the use of foamed concrete in road construction. This paper is based on the published guideline and it presents technical aspects such as compressive and tensile strength, modulus of elasticity and practical aspects such as layer thickness, formwork and recesses. Also discussed is the design process of roads on foamed concrete taking into consideration geotechnical and road-construction aspects. Additionally, the environmental implications and labor conditions are covered.
