Chambroad

Road Petroleum Asphalt

Sourcing the world's high-quality imported raw materials, our road petroleum asphalt has stable quality. With excellent high and low-temperature performance, good adhesion with aggregates, low wax content, anti-aging properties, etc., it is widely used in highways, such as the Beijing-Taiwan Expressway, Zhanlin Expressway, Weiri Expressway, Gongze Expressway, an important project of the "Thirteenth Five-Year Plan" in Tibet, Beijing-Tai'an Expressway.

Advantages

1. Advanced technology: We have independently developed the optimization system of the RTO production plant, and created the industry-leading direct distillation process under normalized reduced pressure;

2. Excellent performance: Excellent high and low-temperature performance, good adhesion with aggregate, low wax content, outstanding anti-aging performance;

3. Stable quality: Sourcing the world's high-quality imported raw materials, our road petroleum asphalt has stable quality.
