Abstract

The invention relates to a modified asphalt material for road rehabilitation and road construction, in particular to a pit interface repairing agent and a preparation method thereof. In the preparation method comprises, 65 parts by weight of asphalt is utilized as a main raw material; (2) modified solution prepared from 6.92-7.42 parts by weight of solvent oil, 2.5-3.0 by weight parts of a styrene-butadiene-styrene block copolymer, 0.05 part by weight of Na2SO3 and 0.03 part by weight of 1-aminoethyl-2-heptadecyl-imidazoline is utilized as a modifier; and (3) 25 parts by weight of kerosene as a diluent; and the preparation method comprises the following steps: mixing and stirring the components to obtain the pit interface repairing agent. The pit interface repairing agent provided by the invention is convenient in use and fast in strength growth; after the interface repairing agent is brushed, 95% of modified indexes can be reached within 1 hour at room temperature of 15 DEG C; and the repairing agent does not need to be heated on the site, and the repaired road surface is slightly different from the original road surface.

Description

technical field [0001] The invention relates to a modified asphalt material for road construction, in particular to a pothole section repair agent and a preparation method thereof. Background technique [0002] In the process of digging and repairing the pit, it is often necessary to brush the asphalt on the interface around the pit. There are differences between ordinary emulsified asphalt oil film and original pavement and repair materials. Thermally modified asphalt requires on-site heating, which is inconvenient to use, consumes a lot of raw materials, and basically cannot be constructed when the weather is cold, with low strength and low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a pit interface repairing agent with convenient use, high strength and simple production process and a preparation method thereof. [0004] The object of the present invention is achieved l...
