Beijing Zhongtian Road Tech has been committed to the R&D and application of durable and economical asphalt additive and road maintenance materials.

ZTA asphalt additives are used to improve the performance of asphalt mixtures and reduce the carbon footprint of asphalt pavements,and solved different problems and needs in more than 30 countries and regions. We have formulated 9 Chinese industry standards and won 40+ patents and honorary certificates, passed SGS, INTERTEK, TÜV Rheinland, ISO international certifications.

The additives aim to make roads more durable, comfortable, economical and environmentally friendly. They also have solved the road surface problems caused by the increasing traffic volume and load and meet the needs of improving road functionality. At the same time, they also solve the needs of environmental protection and resource recycling in asphalt pavement applications.

To meet the needs of increasing traffic volume and load for improving road durability and pavement strength, ZTA-RA additives significantly improve strength of asphalt mixture and overall strength of the pavement structure while ensuring the low temperature and water stability of the asphalt mixture.

2. To solve the demand for improving road functions, permeable pavements paved with ZTA-HV additives have been used in nearly 100 highways. Ultra-thin overlay additives ZTA-VE have been used in pavement preventive maintenance with an area of tens of millions of square meters, extending the life of the original pavement by more than 5 years.

3. To solve the needs of environmental protection and resource recycling, ZTA-MR additive uses waste tires as main raw material, which is more convenient to use than conventional wet rubber asphalt and has lower odor. ZTA-ROA recycling agent restores the bonding properties of the old asphalt and greatly improves the durability of the old asphalt concrete. It has shown superior performance in the selection of multiple projects in China.
