Abstract
An investigation was executed to determine the influence of laboratory aging on the engineering characteristics of polypropylene-modified concrete mixtures (PPMCMs) utilizing different experiments. The design bitumen content was obtained for dense mixture by the Marshall method using aggregate blends which conformed to the American Standard for Testing and Materials, ASTM (D-3515). Marshall stability, Marshall modulus of stiffness, indirect tensile strength, tensile strength ratio, resilient moduli, aging index, cracking index, and extensional viscosity of the aged PPMCMs at temperature of 100â¯Â°C and at two aging levels between 48 and 96â¯h are used to evaluate the performance change of PPMCMs. The PPMCMs achieve the ASTM specified limits; they reveal superior durability, elasticity, and adhesive characteristics with higher resistance to permanent deformation and moisture damage.
