Problems solved by technology

The more serious problem is that even if the existing adhesive layer material is completely demulsified, the construction equipment and the wheels of the transport vehicle will still bring a large amount of adhesive layer material during paving, causing damage to the adhesive layer and destroying the The uniformity and cohesiveness of the adhesive layer reduce the bonding efficiency, which in turn affects the durability of the pavement

preparation example Construction

[0023] The preparation method of the adhesive layer emulsified asphalt that is used for the fast setting of the adhesive layer and does not stick to the wheel of the present invention comprises the following steps,

[0024] Step (A1), according to the required components and their weight percentages, base asphalt: 40% to 60%; water-based resin: 0.1% to 2%; asphalt blending agent: 10 to 15%; asphalt emulsifier: 1% to 3%; hydrochloric acid: 1-3%; emulsified asphalt stabilizer: 0.1%-0.3%; SBS water emulsion 3-5%; the balance is water, and the ingredients are weighed;

[0025] Step (B1), heating base asphalt to 160-180°C, adding asphalt blending agent and stirring for 15 minutes;

[0026] Step (C1), add emulsified asphalt stabilizer to the asphalt compounded in step (B1) and stir for 10 minutes;

[0027] Step (D1), dilute the asphalt emulsifier, SBS water emulsion and water-based resin in proportion with water, add hydrochloric acid, adjust the pH value to 1.5-2.5, and prepare so...

Embodiment 1

[0030] Embodiment 1 of the present invention, the use method of the sticky layer emulsified asphalt that is used for fast setting and non-sticking wheel of the bonding layer, comprises the following steps,

[0031] In step (A2), select 97% of fast-setting and non-sticky emulsified asphalt and 3% of viscosifying and toughening composite aqueous emulsion.

Abstract

The invention discloses quick-setting wheel-sticking-free adhesive layer emulsified asphalt for an adhesive layer as well as a preparation method and a use method of the quick-setting wheel-sticking-free adhesive layer emulsified asphalt, and the quick-setting wheel-sticking-free adhesive layer emulsified asphalt is prepared from the following components in percentage by weight: 40-60% of matrix asphalt; 0.1%-2% of water-based resin; 10%-15% of an asphalt blending agent; 1%-3% of an asphalt emulsifier; 1-3% of hydrochloric acid; 0.1%-0.3% of an emulsified asphalt stabilizer; 3-5% of an SBS aqueous emulsion; remaining amount of water. The invention has the advantages of high demulsification speed and high forming speed, overcomes the fragility of hard asphalt, has certain flexibility, greatly enhances the pavement performance and construction efficiency of the adhesive layer, has the characteristic of no wheel sticking, avoids the damage of construction equipment and transport vehicles to the adhesive layer material, enhances the integrity of the adhesive layer, and paves the non-stick equipment; the paving is convenient, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of paving for road construction and maintenance, in particular to a fast-setting and non-sticky adhesive layer emulsified asphalt used for an adhesive layer and a method for preparing and using the same. Background technique [0002] In road construction and maintenance projects, the process of spreading sticky layer materials is usually used between adjacent structural layers to promote the formation of an overall stressed structure between layers, thereby reducing the damage caused by traffic loads such as shifting and hugging of inter-layer structures . The interlayer bonding strength and anti-skid ability provided by the adhesive layer material can bond the interlayers of the pavement structure into a whole and improve the durability of the pavement. However, in the actual construction process, the existing sticky layer materials have slow demulsification speed and slow formation of strength after the s...
