Abstract:
This study examines the mechanical properties of porous asphalt pavement with varying polymers (elastomeric and reactive elastomeric terpolymer) and types of aggregates. Two aggregate compositions were employed: exclusively limestone and a blend of limestone and basalt aggregates. The findings reveal that mixtures containing the base bitumen failed to satisfy the porous asphalt's Cantabro loss test criterion, which mandates a maximum threshold of 20%. Conversely, asphalt mixtures modified with polymers demonstrated superior performance in terms of permeability, Cantabro loss, and the ratio of indirect tensile strength.
