Spent bleaching clay asphalt mixture modifier and preparation method thereof

Abstract

The invention provides a spent bleaching clay asphalt mixture modifier and a preparation method thereof, and relates to the technical field of high polymer materials and road engineering. The spent bleaching clay asphalt mixture modifier comprises the following components: spent bleaching clay, hard asphalt, a polymer additive, a stabilizer, a terpene resin, rubber filling oil and oxidized polyethlene wax. According to the spent bleaching clay asphalt mixture modifier provided by the invention, the modifier capable of improving the performance of the spent bleaching clay asphalt mixture is prepared by compounding the spent bleaching clay with other raw materials; and when the modifier is used for the spent bleaching clay asphalt mixture, the modified spent bleaching clay asphalt mixture has the advantages of high-temperature stability, low-temperature crack resistance, water stability, fatigue resistance, aging resistance and the like, so that various performance indexes of the modified spent bleaching clay asphalt mixture can meet the technical requirements, the pavement paved by the modified asphalt mixture can meet the current load demand, and the service life of the pavement isprolonged.

Description

technical field [0001] The invention relates to the technical field of polymer materials and road engineering, in particular to a waste clay asphalt mixture modifier and a preparation method thereof. Background technique [0002] The material used to pave flexible pavements is asphalt mixture. With the development of economy and technology, the traffic load of modern roads increases sharply, and the load capacity increases sharply, so the performance requirements of asphalt mixture are required to be increased year by year. The original The pavement paved with mixture produced by ordinary heavy traffic asphalt can no longer meet the status quo, and the service life is greatly shortened. [0003] In view of this, it is an urgent technical problem to provide an asphalt mixture modifier to modify the asphalt mixture so that the performance of the modified asphalt mixture can meet the use requirements. Contents of the invention [0004] The purpose of the present invention is...
