Abstract

The invention discloses a direct-feeding type asphalt warm-mixing material. The direct-feeding type asphalt warm-mixing material is a mixture of a copolymer of polyethylene wax-maleic anhydride and zeolite powder. The preparation method of the direct-feeding type asphalt warm-mixing material comprises the following steps: (1) preparing the copolymer of polyethylene wax-maleic anhydride; (2) weighing the copolymer of polyethylene wax-maleic anhydride and mixing with the zeolite powder to obtain the target product. By adopting the warm-mixing material, the construction workability of the asphalt mixture can be effectively improved, the temperatures of the asphalt mixture during the mixing, paving and grinding processes are 20-40 DEG C lower than those of the traditional hot-mix asphalt mixture, and each index of the warm-mixing material can reach the performance index of the traditional hot-mix asphalt mixture. By adopting the warm-mixing material provided by the invention, special added equipment is not needed, the production is convenient, and the yield of an asphalt mixing plant is not influenced.

Description

technical field

[0001] The invention relates to a road construction material additive and a preparation method thereof, in particular to a direct-throwing asphalt warm-mix material and a preparation method thereof. Background technique

[0002] As a seamless continuous pavement, asphalt road is widely used because it has sufficient mechanical strength, can adapt to various driving loads, and has the characteristics of stable driving, comfortable driving, low noise and easy maintenance.

[0003] At present, the familiar asphalt mixtures for asphalt pavement construction and maintenance mainly include hot mix asphalt mixture and cold mix asphalt mixture. Judging from the quantity ratio used, hot mix asphalt mixture accounts for the vast majority. With the continuous improvement of people's awareness level, they began to realize the existence of problems such as toxic waste gas, excessive energy consumption and aging in the production and use of hot mix asphalt mixture; in add...
