This study focuses on investigating the strength properties of polymer-modified asphalt concrete mixtures. The
main objective is to evaluate the influence of polymer additives on the mechanical performance of asphalt concrete, including
compressive strength, flexibility, and resistance to deformation. The methodology is based on laboratory testing, including
Marshall stability analysis, deformation behavior under dynamic loading, and temperature-dependent strength
evaluation. Specimens modified with different percentages of polymer additives were prepared and compared. The results
demonstrate that polymer modification significantly enhances the load-bearing capacity of asphalt concrete and reduces its
susceptibility to softening at elevated temperatures. Furthermore, improvements in crack resistance and overall service life were observed. The findings confirm the practical importance of polymer-modified asphalt concrete in modern
road construction for producing durable, high-performance pavement materials capable of withstanding heavy traffic and
harsh environmental conditions.
