1. Introduction to Highly Permeable Emulsified Asphalt Products

Highly permeable emulsified asphalt is a type of emulsified asphalt formed by using a medium crack cationic emulsifier to emulsify asphalt mixed with a penetrant. Its asphalt content is generally between 40% and 45%. This material has excellent permeability, able to penetrate the base layer by 5-10mm, and has good adhesion, which can bond with the base layer as a whole.

2. Definition and Characteristics of Highly Permeable Emulsified Asphalt

High permeability emulsified asphalt is a lotion made of asphalt and water under the action of emulsifier, which is characterized by high emulsification, low viscosity and good permeability. This material has the following characteristics:

(1) Good penetration performance: able to quickly penetrate into the micro cracks of the road surface, forming a tight asphalt combination, improving the crack resistance and durability of the road.

(2) Good adhesion: able to bond with the base layer as a whole, enhancing the overall integrity and stability of the road surface.

(3) Good environmental performance: cold construction operation, no need for heating, non-toxic smoke, no solvents, no pollution to the environment, easy to carry out safe construction.

3. Advantages and environmental performance of high penetration emulsified asphalt

Compared with traditional hot mix asphalt, high permeability emulsified asphalt has the following advantages:

(1) Fast construction speed: The process is simple, the construction speed is fast, and it can reduce energy consumption and air pollution.

(2) Good environmental performance: cold construction operation, no need for heating, non-toxic smoke, no solvents, no pollution to the environment, easy to carry out safe construction.

4. Application field of high permeability emulsified asphalt

Highly permeable emulsified asphalt has a wide range of applications in infrastructure construction and road maintenance:

(1) Infrastructure construction: widely used in the construction of roadbed, base layer, surface layer and other parts, it can be quickly absorbed by the road surface, form a tight asphalt binder, and improve the bearing capacity and crack resistance of the road.

(2) Road maintenance: Used for road surface repair, sealing road joints, drip holes and other projects, it can effectively penetrate into the micro cracks of the road surface, improve the compactness and durability of the road surface.
