Abstract

The invention relates to a sticky layer emulsified asphalt and a preparation method thereof. The emulsified asphalt comprises the following components accounting for its total mass percentage: 40% to 60% of low-grade asphalt, 0 to 3% of emulsifying additives, 0 to 3 % modifier, 0.2%~2% asphalt emulsifier, 0.2~2% acid-base regulator, and the rest is water. The preparation method includes: firstly, two intermediate materials of easy emulsification modified low-grade asphalt and soap liquid are prepared, followed by high-speed grinding of the intermediate materials to form unstabilized emulsified asphalt; finally, the unstabilized emulsified asphalt is stirred at a constant temperature, Obtain sticky emulsified asphalt. The beneficial effect of the present invention is that the demulsification speed is fast and the forming is fast, thereby greatly improving the construction efficiency; it has the characteristics of non-stick wheels, which avoids the damage of construction equipment and transportation vehicles to the adhesive layer materials, and improves the bonding efficiency and bonding efficiency. Strength, thereby improving the durability of the pavement; asphalt has good high-temperature performance; at the same time, the process is simple and practical, which is conducive to popularization and application.

Description

technical field [0001] The invention relates to the field of road materials, in particular to a fast-setting, non-sticky emulsified asphalt used for bonding layers between structural layers in newly built or maintained road surfaces and a preparation method thereof. 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. [0003] However, in the actual construction process, the existing sticky layer materials have slow demulsification speed and slow formation of strength after t...
