Asphalt pavement full service
Asphalt production is mainly divided into two types: raw materials and finished products. Finished products are divided into ordinary mixed materials and modified asphalt, which also determines that different equipment is needed to meet the production of the two materials. Macroad is committed to providing customers with efficient, intelligent and environmentally friendly full-cycle production support.
Five major equipment used in asphalt production
| Equipment Name | Core Features | Output Product | Technical threshold |
|---|---|---|---|
| Asphalt Debarrel Equipment | Heat and melt barreled/solid asphalt and transfer it to asphalt tank | Liquid asphalt (raw material) | Thermal energy control and anti-sticking technology |
| Asphalt Emulsification Equipment | Mix liquid asphalt with water and emulsifier to form an emulsion | Emulsified asphalt (finished product) | Emulsion stability control |
| Modified Asphalt Equipment | Adding modifiers such as rubber, resin, and high molecular polymer to liquid asphalt | Modified asphalt (finished product) | Dispersion uniformity, temperature control accuracy |
| Asphalt Recycling Equipment | Recycling of waste asphalt (RAP) into usable asphalt | Recycled asphalt (raw material/finished product) | Waste sorting and recycling process |
| Asphalt Mixing Plant | Mix aggregate, asphalt and filler in proportion to form asphalt mixture | Asphalt mixture (finished product) | Metering accuracy and thermal efficiency management |
1. Raw material processing stage: asphalt debarreling/recycling equipment
Asphalt debarrel equipment
Asphalt debarreling equipment is the front end of the production line, solving the problem of pretreatment of solid asphalt raw materials.
It only processes the asphalt form conversion (barrel → liquid), without changing the chemical properties of the asphalt.
Asphalt recycling equipment
Asphalt recycling equipment is mainly a circular economy link, processing waste asphalt mixture. The input is RAP (waste mixture) and the output is recycled asphalt raw material.
2. Mixture production stage
Asphalt mixing plant is the ultimate production equipment for asphalt mixture, integrating aggregate, asphalt and filler to produce a solid finished product (asphalt mixture).
Batch Mix Asphalt Plant
Batch Mix Asphalt Plant: Provides high-quality asphalt, suitable for long-term large-scale production needs.
Drum Mix Asphalt Plant
Stable output, drum mix asphalt plant is very suitable for large-scale projects that require a continuous supply of asphalt.
Macroad provides customized solutions to meet diverse construction needs. Our asphalt plants are designed for global customers, integrating advanced technology and modular concepts, suitable for highways, airport roads, municipal roads, rural roads and other scenarios.
Technical advantages
- Accurate ratio: adopt the first error control technology and dynamic precision control secondary metering technology to strictly guarantee the oil-stone ratio and the quality of the finished asphalt
- Intelligent control system: fully automated operation interface, accurate measurement of aggregate, asphalt and additive ratio.
- Environmental protection design: a variety of dust removal schemes to choose from, gravity dust removal, cyclone dust removal, volute dust removal, bag dust removal, water dust removal, to meet your environmental protection needs
- Durable structure: core parts and easily worn parts are structurally optimized to ensure drive stability and fault prevention.
3. Asphalt modification stage
Asphalt emulsification equipment
Asphalt emulsification equipment is the core equipment for producing cold-mix asphalt, suitable for non-high-temperature construction scenarios (such as road maintenance). The product is an oil-in-water emulsion (asphalt content 50%-60%), which requires the addition of stabilizers.
Modified asphalt equipment
Modified asphalt production equipment is mainly used to improve asphalt performance (such as anti-rutting and anti-fatigue) and is used for high-grade roads. The molecular structure of asphalt is changed through physical/chemical modification (such as SBS modification requires twin-screw extrusion).
How Macroad solves the technical barriers
