Foam Concrete as New Material in Road Constructions

The article presents the possibilities of using lightweight concrete - foam concrete in road construction. Principles of sustainable development create the need to develop new building materials. Foam concrete is a type of lightweight concrete that has many advantages compared to conventional building materials, for example low density and thermal insulation characteristics. With current development level, any negatively influencing material features are constantly eliminated as well. This paper deals with the substitution of hydraulically bound mixtures by cement foam concrete Poroflow 17-5. The executed assessment is according to the methodology of assessing the existing asphalt pavements in Slovak Republic. The special calculation was used to estimate the modulus of foamed concrete Poroflow 17-5 based on the results of static load tests conducted using the experimental in-situ stand.
