The main uses of national standard modified coal pitch include:

1. Production of various asphalt additives

Modified pitch is an important raw material for producing various asphalt additives. It can be used to manufacture high-performance asphalt additives such as antioxidants and UV resistance agents.

2. Application in construction industry

In the construction industry, modified pitch is widely used in the preparation of various building materials, such as waterproof membranes, anti-corrosion coatings, and insulation boards.

3. Improvement of polymer-modified asphalt

Polymer-modified asphalt is a material widely used in modern road engineering. Modified pitch can be added as an additive to polymer-modified asphalt to enhance its performance. Through chemical reactions, modified pitch undergoes cross-linking with polymer-modified asphalt, forming a denser network structure that improves the asphalt's fatigue resistance and durability, making the pavement more wear-resistant, skid-resistant, and enhancing its waterproofing properties.

Product features: (1) Asphalt exhibits strong adhesion and viscosity, maintaining its shape under various pressures and adapting to different climatic conditions and geological changes.

(2) Asphalt can withstand prolonged exposure to sunlight and rainwater erosion, resisting aging and deterioration. It is highly sensitive to temperature, exhibiting different states (such as liquid, solid, and semi-solid) at different temperatures. This property allows it to flow at high temperatures to meet construction needs while remaining stable at low temperatures.

(3) Asphalt has excellent water resistance. It can maintain high stability and waterproof functionality even when submerged in water for extended periods.

(4) Asphalt materials typically possess strong corrosion resistance, capable of withstanding various chemical corrosion and oxidation. The production and construction costs of asphalt are relatively low, making it suitable for large-scale infrastructure projects.
