Mechanical properties of cement and cement-asphalt matrices with rubber powder

Cement matrices are known from concrete testing. Cement-asphalt matrices made of cement and asphalt emulsion are used in mineral-cement-emulsion mixes (MCEM). The matric strength in MCEM mixtures has not been studied so far. Cement-asphalt matrices with 0/1 mm rubber powder are proposed by the author for use in the MCEM [3, 26]. In this paper the results of the investigation of the mechanical properties of matrices are presented for comparative purposes and for the preliminary evaluation of their suitability for MCEM. The following tests were made: indirect tensile strength, bending strength, compressive strength and rigidity modules in NAT and 4 PB-PR
