Problems solved by technology

Moreover, groundwater enters the asphalt layer through the cement layer, and water enters the asphalt layer through the cracks, which will easily cause cracks and damage the road surface.
At present, the commonly used interlayer adhesive mainly includes SBR modified asphalt, but its waterproof, adhesive performance and temperature stability are low.

Embodiment 1

[0028] A preparation method for an asphalt road interlayer adhesive, comprising the steps of:

[0029] Cyclodextrin polyrotaxanes were prepared with reference to the method in the literature Liu Y, Yang Y W, Chen Y, Zou HX.Polyrotaxane with Cyclodextrinsas Stoppers and Its Assembly Behavior[J].Macromolecules,2005,38(13):5838-5840;

[0030] Add oil-based asphalt repair agent to styrene maleic anhydride (surfactant) aqueous solution, disperse and emulsify at a high speed for 10 minutes and mix to obtain an emulsion; slowly add methyl etherified hexamethylolmelamine prepolymer solution dropwise to the emulsion to Stir and mix at a speed of 500r / min. After the dropwise addition, raise the temperature to 65°C, then adjust the pH to 5 with acetic acid aqueous solution, then raise the temperature to 80°C, keep stirring and react for 2 hours, cool to room temperature, filter, wash, and dry to obtain self-healing Microcapsules, wherein the weight ratio of the methylated hexamethylolmel...

Description

technical field [0001] The invention relates to the technical field of road adhesives, in particular to an asphalt road interlayer adhesive and a preparation method thereof. Background technique [0002] Compared with cement concrete pavement, the surface of asphalt pavement is flat and seamless, with little driving vibration, low noise, fast open traffic and easy maintenance, especially suitable for road construction in stages. Therefore, asphalt pavement is more and more widely used in new roads. For many old cement concrete pavements, the "white to black" method is generally adopted in the process of renovation and reconstruction, that is, on the basis of the treatment of the original cement concrete pavement, an asphalt concrete surface is added. [0003] With the extensive application of the "white to black" construction and maintenance technology of composite pavement, such composite pavement is widely used in roads such as squares, airports, factories, and residentia...
