Product Detail
Product Introduction
High modulus asphalt is different from ordinary resin reinforced asphalt. It uses inorganic nanomaterials to change the micro molecular arrangement of the asphalt mixture to improve the matrix strength of the bonding material. Polar polymer materials are used to improve the adhesion between the bonding asphalt and stone. Compared with conventional high modulus additives, its overall uniformity is greatly improved, and it is easy to mix and construct, with good thermal stability and durability.
Product Features
Additives with higher modulus than conventional ones, with rutting times exceeding 20000; Good thermal stability and durability, because the composition of the material contains more anti-aging stable components, and the content of organic polymers is relatively small. High cost-effectiveness, with lower material costs compared to types that add organic resin materials. High modulus asphalt mixtures are mostly used for heavy-duty transportation, high-temperature areas, long and long longitudinal slope sections, and airport pavement, mainly to solve deformation diseases such as rutting caused by insufficient pavement strength and poor high-temperature performance of asphalt mixtures.
