Highway Project with Macroad Asphalt Mix Plant Achieve Efficiency

Highway Construction: From Problems to Solutions

Highway high demand for asphalt, need to meet the high temperature stability, rutting resistance, crack resistance and other properties, the mix grading accuracy requirements are stringent.

1.Quality defects: Insufficient grading accuracy, high fluctuation of oil-rock ratio and severe material segregation

Equipped with hot aggregate metering hopper with cumulative metering as well as overflow pipe and waste pipe, it has automatic compensation for fallout and overweight alarm and locking function to improve weighing accuracy;
Built-in upper and lower air extraction and dust removal pipeline design, eliminating the airflow-induced weighing value drift, ensuring weighing accuracy;
Adopting the first batch of error control technology to improve the weighing accuracy and ensure the quality.
Dynamic precision control of the secondary measurement technology, based on the amount of stone to the asphalt secondary correction measurement, strictly guarantee the oil/stone ratio, to avoid the loss of asphalt, but also to ensure the quality of the finished product of asphalt

2.Capacity bottlenecks: Unstable equipment capacity, poor production continuity and high equipment failure rate

Adopting vibration inclination optimization design, full screening area, improve screening efficiency, ensure strict grade ratio, ensure the output.

3.Environmental risks:Excessive dust fugitive emissions, substandard treatment of emissions and noise pollution

The outer cover of the screen body is equipped with an exhaust duct, effectively preventing dust from escaping, fully enclosed structure, negative pressure dust-proof, no dust leakage, avoiding environmental pollution.
Equipped with high-pressure pulse type bag filter, high dust removal efficiency, to meet the local environmental requirements, to avoid complaints due to environmental issues.

Core equipment selection guide

In highway construction, choosing the right asphalt mixing plant is crucial. Batch type asphalt mixing plants(ALQ Series) and mobile asphalt batching mixing plants(ALYQ Series) are equipped with highly efficient production capacity and excellent mixing performance to meet the stringent requirements of asphalt mixtures for highways. They not only support the need for high temperature stability and rutting resistance, but also provide environmental protection and production efficiency. Therefore, understanding the features and applicable scenarios of these two plants is crucial to the success of the project.
