Laboratory Comparison of Stilobit and PROPolymer MA-CK
Incoming article date: 08.11.2025To enhance the performance characteristics of asphalt concrete mixtures in high-temperature conditions typical of hot climates, researchers actively employ various stabilizing additives aimed at increasing the durability of road pavements. One traditional solution is the use of the Sтилобит modifier, which improves the resistance of asphalt concrete to deformations, rutting, and cracking caused by intense traffic loads and climatic factors. However, Sтилобит has several drawbacks, including insufficient binder stability at high temperatures and a limited ability to ensure optimal material density, which can reduce the overall effectiveness of the pavement. These limitations drive the search for more modern and efficient alternatives that can balance quality and cost-effectiveness. Within the scope of this study, a new stabilizing modifier, PROPolymer MA-CK, was evaluated as a promising alternative to Sтилобит. For comparative analysis, two asphalt concrete mixtures were prepared: one with the addition of Sтилобит and the other with PROPolymer MA-CK. Laboratory tests demonstrated that the mixture with PROPolymer MA-CK exhibits improved performance characteristics, including enhanced resistance to rutting, better binder stability, and higher material density, which contributes to reducing the risk of deformations. Thus, PROPolymer MA-CK can be considered a more effective alternative to Sтилобит, providing not only increased reliability and durability of road pavements but also potential cost reductions in the construction and maintenance of roads.
