STUDY OF TOUGHNESS AND DEFORMATION MODULUS OF BITUMEN COMPOSITES AFTER AGING IN BIOLOGICALLY AGGRESSIVE ENVIRONMENT
The article presents and analyzes the results of tests of bituminous composites aged in a biological environment for 6 months carried out on the Geppler consistometer. Hardness indices and modulus of elasticity of materials are obtained. The essential influence of initial properties of raw materials the bituminous composites consist of and technology of sample manufacture on the values obtained in the course of the tests is identified. The dependences of changes in hardness and elastic modulus of dense and porous asphalt materials before and after bio-influence are established.
