Bitumen Modulus HWTD Hamburg Anti Rutting Asphalt Additives are designed for heavy-duty traffic, municipal crossroads, and highways. This high-performance modifier is essential for modern asphalt road projects, enhancing the surface performance of aggregates to resist road ruts and significantly extending pavement service life.
The ZTA-RA additive is superior to traditional modified asphalt processes. It specifically improves low-temperature resistance, prevents water loss, and increases Marshall Stability and immersion stability of the asphalt mixture.

Specifically engineered for demanding environments:
With advanced production bases, the annual output reaches 60,000 tons of asphalt additives and 40,000 tons of ARA anti-rutting agents, meeting diverse global demands for road maintenance and construction.
A: It is designed to enhance the modulus and stability of asphalt mixtures, specifically to prevent rutting and deformation in heavy-duty traffic areas like crossroads and highways.
A: The additive is mixed directly in the asphalt mixing plant during the production of the asphalt mixture, ensuring uniform distribution.
A: The typical dosage ranges from 0.2% to 0.4% of the asphalt mixture by weight, depending on the specific road requirements and traffic load.
A: Yes, it is suitable for use in the middle, upper, and lower layers of asphalt pavement construction and maintenance.
A: ZTA-RA can be stored at room temperature in a dry environment. The hot-melt bags make it convenient to handle and store without special climate control.
A: It offers higher softening points, better adhesion to aggregates, and superior resistance to both high-temperature rutting and low-temperature cracking compared to many traditional processes.
