Abstract

The invention discloses multifunctional environment-friendly modified asphalt and a preparation method thereof, and belongs to the technical field of pavement materials. Zinc chloride and sodium bicarbonate solution are mixed, precipitated and calcined to prepare nano active zinc oxide, devulcanized rubber powder is prepared by waster rubber powder, tourmaline is crushed and grinded with the nano active zinc oxide and attapulgite in a mortar to prepare mixed powder, surface modification is performed by silane coupling agents to prepare functional powder with good dispersity and an air adsorbing purification function, finally, petroleum asphalt is heated and softened, the devulcanized rubber powder is added, heated and stirred, the functional powder is added, and the materials are uniformly stirred to obtain the multifunctional environment-friendly modified asphalt. The multifunctional environment-friendly modified asphalt has excellent pavement performance, has various functions of hot-mixing emission reduction, flame retarding, smoke suppressing, air purification, alleviation of urban 'heat island effect' and the like, and can serve as an asphalt pavement material.

Description

technical field [0001] The invention discloses a multifunctional environment-friendly modified asphalt and a preparation method thereof, belonging to the technical field of pavement materials. Background technique [0002] At present, developing a low-carbon economy and building a low-carbon society have become the strategic priorities of China and the world. With the increase of people's awareness of environmental protection, more requirements have been put forward for the functions of pavement materials. Road materials are not limited to the goal of good road performance and durability. Low-carbon environmental protection pavement materials with multi-functional properties have become road One of the main research directions of the researchers. However, most of the asphalt materials with environmental protection effects are formed by adulterating a certain amount of additives with special properties on the premise of basically not affecting or improving the performance of...
