摘要

The expressway is a product of a country's economic and social development process, and it is one of the standards to measure the modernization level of a country's road transportation and automobile industry. With the progress of our society, the total mileage of highways in our country has exceeded 5 million kilometers. At present, highways in our country are basically asphalt pavements, and the durability of asphalt concrete pavements has attracted more and more attention. Most scholars have proved through various tests that the impact of asphalt performance on the entire mixture plays a decisive role. For expressways, by selecting the appropriate ratio and its asphalt raw materials, adding 0.3%-0.5% of high modulus asphalt concrete admixtures, the road performance of the asphalt mixture can be improved.
