Problems solved by technology

At present, the commonly used asphalt pavement sealing material is emulsified asphalt, but its function is single, and it only has the effect of waterproofing, and the preventive maintenance effect on high-grade asphalt pavement is not obvious.
[0004] At present, the commonly used preventive maintenance measures such as slurry seal and micro-surfacing have technical difficulties such as rough surface, loud driving noise, and inconsistent appearance color

Embodiment 1

[0040] Weigh each component according to the following formula: 35% emulsified asphalt; 3% modifier; 20% tap water; 12% aggregate; 15% filler; 6% anti-ultraviolet color paste; 0.5% wetting and dispersing agent; 0.9%; thickener 0.5%; defoamer 0.1%; surfactant 7%;

[0041] The preparation method of embodiment 1 is:

[0042] a. Under stirring conditions, disperse the wetting and dispersing agent in tap water, and add 20-30% of the weight of the defoamer, stir evenly, and add anti-settling agent and color paste under stirring at 800-1200r / min, Then stir and disperse until the fineness reaches below 60 μm, add the remaining defoamer under stirring conditions, stir and defoam for 3-5 minutes, and prepare the pigment slurry;

[0043] b. Under stirring conditions, add the modifier to the emulsified asphalt, stir at 800-1200r / min for 10-15min, then add the pigment slurry prepared in step a, add aggregate and filler, and stir for 30-40min , add surfactant and thickener, stir evenly, a...

Embodiment 2

[0045] Weigh each component according to the formula quantity, emulsified asphalt 40%; modifier 5%; tap water 13%; aggregate 12%; filler 18%; anti-ultraviolet color paste 6%; 0.7%; Thickener 0.5%; Defoamer 0.2%; Surfactant 4%.

[0046] The preparation method of embodiment 2 is the same as embodiment 1, and the stirring speed is 1000r / min.

Embodiment 3

Abstract

The invention discloses a novel ultrathin road surface sealing layer treatment material and a preparation method thereof. The material comprises the following components: 33-51% of emulsified asphalt, 3-6% of modifier, 9-20% of tap water, 12-15% of aggregates, 10-18% of padding, 3-8% of ultraviolet-proof color paste, 0.3-1% of wetting dispersant, 0.4-0.9% of anti-settling agent, 0.2-0.5% of thickening agent, 0.1-0.3% of defoaming agent and 4-7% of surfactant. Emulsified asphalt is secondarily modified, so that the bonding property and thermal stability of the material are both greatly improved. In addition, the secondarily-modified emulsified asphalt is blended with special padding, chemical additives and aggregates (mineral particles with certain strength as well as edges and corners) according to a certain proportion to form a mixture which can be sprayed in construction; the mixture is sprayed on a road surface to form a 3-5mm ultrathin film with the effects such as water resistance, skid resistance, wear resistance and the like.

Description

【Technical field】 [0001] The invention relates to a novel ultra-thin road surface sealing layer treatment material and a preparation method thereof. 【Background technique】 [0002] With the popularization of high-grade modified asphalt pavement, the pressure of asphalt pavement maintenance is getting heavier and higher, and the maintenance cost is also getting higher and higher. Preventive maintenance. Therefore, the study of preventive maintenance is particularly important. [0003] Preventive maintenance is of great significance to prevent or delay pavement diseases, maintain pavement service functions, prolong pavement life and reduce pavement life cycle maintenance costs, and has become an important means of road maintenance at home and abroad. Pavement sealant treatment is an important means of preventive maintenance of asphalt pavement. At present, emulsified asphalt is commonly used as asphalt road surface sealing material, but its function is single, and it only h...
