Embodiment 1

[0048] 30# base asphalt 500g, fast-cracking cationic emulsifier 10g, hydroxymethyl cellulose 8g, sulfonated asphalt powder 60g, water 500g.

[0049] Put 10g of emulsifier in the container for later use, heat the water to 70°C, add it into the container containing the emulsifier, stir until the emulsifier is completely dissolved in hot water, add 8g of hydroxymethylcellulose, and mix well. Get soap. Keep the temperature of the soap solution at 70°C; heat 500g of asphalt to 160°C, and add 60g of sulfonated asphalt powder to it. Stir well. Keep the temperature at 160°C; preheat the colloid mill to 70°C, add the configured soap solution to it, turn on the colloid mill, set the speed of the colloid mill to 7000r / min, and add base asphalt to it after the rotation is stable. Put the mixed asphalt and soap solution together through a colloid mill and shear at high speed for 5 minutes to obtain non-stick wheel emulsified asphalt.

Embodiment 2

[0051] 20# base asphalt 520g, cationic emulsifier 10g, methyl cellulose 8g, sulfonated asphalt powder 50g, water 500g.

[0052] Put 10g of emulsifier in the container for later use, heat the water to 70°C, add it into the container containing the emulsifier, stir until the emulsifier is completely dissolved in hot water, add 8g of hydroxymethylcellulose, and mix well. Get soap. Keep the temperature of the soap solution at 70°C; heat 520g of asphalt to 170°C, and add 50g of sulfonated asphalt powder to it. Stir well. Keep the temperature at 170°C; preheat the colloid mill to 70°C, add the configured soap solution to it, turn on the colloid mill, set the speed of the colloid mill to 8000r / min, and add base asphalt to it after the rotation is stable. Put the mixed asphalt and soap solution together through a colloid mill and shear at high speed for 8 minutes to obtain non-stick wheel emulsified asphalt.

Embodiment 3

[0054] 20# base asphalt 180g, 30# base asphalt 200g, quaternary ammonium salt cationic emulsifier 8g, hydroxymethyl cellulose 5g, sulfonated asphalt powder 30g, rock asphalt powder 10g, water 350g.

[0055] Put 8g of emulsifier in the container for later use, heat the water to 70°C, add it into the container containing the emulsifier, stir until the emulsifier is completely dissolved in hot water, add 5g of hydroxymethylcellulose, and mix well. Get soap. Keep the temperature of the soap solution at 70°C; heat 180g of 20# asphalt and 200g of 30# asphalt to 170°C, mix well and add 30g of sulfonated asphalt powder and 10g of rock asphalt powder to it. Stir well. Keep the temperature at 170°C; preheat the colloid mill to 70°C, add the configured soap solution to it, turn on the colloid mill, set the speed of the colloid mill to 7500r / min, and add base asphalt to it after the rotation is stable. Put the mixed asphalt and soap solution together through a colloid mill and shear at ...

Abstract

The invention discloses wheel-sticking-free emulsified asphalt and a preparation method thereof, which relate to the technical field of pavement asphalt materials, and solve the problem that an existing emulsified asphalt material adheres to a tire of a construction vehicle. The wheel-sticking-free emulsified asphalt material is prepared from the following components in parts by mass: 30-60 partsof matrix asphalt, 0.5-5 part of an emulsifier, 5-15 parts of a modifier and 30-60 parts of water, wherein the modifier comprises sulfonated asphalt powder. According to the technical scheme providedby the invention, the softening point of the emulsified asphalt can be increased, so that the emulsified asphalt is not easy to soften, and the emulsified asphalt is difficult to adhere to a construction wheel.

Description

technical field [0001] The invention relates to the technical field of pavement asphalt materials, in particular to a non-stick wheel emulsified asphalt and a preparation method thereof Background technique [0002] The theory of layered elastic system is adopted in the design of asphalt pavement in our country, and the assumption is that the material of each layer is homogeneous, continuous, isotropic, and there is no friction between layers. Layers are usually assumed to be continuous by default. However, in actual engineering, it is found that interlayer bonding has a great influence on the pavement performance of asphalt mixture, and the interlayer bonding effect of each structural layer of asphalt pavement cannot be ignored. The quality of interlayer bonding is one of the important factors affecting the service life of the pavement. If the interlayer bonding is not good, the integrity of the pavement structure will be destroyed, the overall resistance of the pavement s...
