Asphalt concrete mixing plant is critical for construction quality and efficiency in the asphalt pavement. Most of asphalt mixing plants for domestic high grade roads are imported and the capacity is at least 160t/h. With years of experience in asphalt concrete production and construction, we know well that asphalt mixing plant efficiency and concrete quality has direct impact on the failure of asphalt plant and like to provide some information to promote asphalt concrete development and improve high grade asphalt pavement quality.
