Abstract

With the large-scale construction of advanced roads, the requirements for the performance and durability of asphalt pavements are getting higher and higher, and improving the performance of existing asphalt materials is an important basis to meet this requirement. Factors that affect the performance and service life of asphalt pavements include the aging resistance of the asphalt and the compositional design of the mix. Montmorillonite has a very wide range of applications, especially inorganic and organic modifications, which make it rich in many unique properties, further expanding the application field, especially in polymer layer nanocomposites. In view of this, this paper proposes the modification of asphalt mixtures with nano-montmorillonite and further explores the performance of MMT-modified asphalt through practical experiments on high-temperature rutting, low-temperature cracking, water resistance and fatigue resistance. The experimental results in this paper show that the addition of organic montmorillonite can significantly improve the water stability of asphalt mixtures and the improvement effect is most obvious when the addition amount is 6%.
