Our company owns research labs, a large-scale manufacturing and processing plant and a nationwide sales network. We cooperate with world renowned scientific institution for pavement, and learn from established scientific results and application technology from other countries. We also join hands with the Key Laboratory of Road and Traffic Engineering of the Ministry of Education, Tongji University on long-term collaboration to develop such products as colored pavement material, road maintenance material, special asphalt and asphalt processing equipment.
Being “science-led and service-oriented” is our principle. So far we have applied for 124 national patents, owned 7 national patents, won 1 nation-level innovation fund and 2 Shanghai innovation fund. We are recognized as a nation-level high-tech enterprise, Shanghai energy-saving and environment-protecting enterprise, outstanding Shanghai enterprise that converts new technological achievements into productivity, and Shanghai patent activity experimental enterprise, having established the brand of “Roadphalt”.
Roadphalt all-weather cold paving material is a kind of high-tech road patching material, mixed and prepared by using Roadphalt high-performance cold paving additive, asphalt and aggregate according to certain processing technology, with an appearance of black grain-like solid, slight petroleum smell, insoluble in water, insensitive to motive impact and static electricity, and with stable properties.
