Problems solved by technology

[0002] In recent years, due to the rapid increase in oil prices and the environmental pressure brought by waste polymer materials, the addition of waste polymer materials to modified asphalt and its application in roads has attracted widespread attention; my country's natural asphalt reserves are abundant, surface Due to the huge pressure on petroleum asphalt resources, natural asphalt is often used to replace parts. Bio-asphalt materials contain polar ester groups and non-polar linear alkanes, which can be used as interface agents to increase the compatibility of saturated hydrocarbons and asphaltenes in asphalt. , therefore, it can better stabilize the colloidal structure of asphalt under load, but the road performance cannot meet the requirements of our country’s regulations if only natural asphalt or bio-asphalt is used.
[0003] In real life, resources such as plant stalks and animal manure are seriously wasted, and white garbage cannot be recycled, which does not conform to the concept of sustainable development. Therefore, a combination of waste polymer materials and natural asphalt or bio-asphalt is needed. prepared asphalt mixture
