Development and Application of Real-Time Quality Monitoring System of Hot Mixed Asphalt Mixture

As the stability of quality of hot mixed asphalt mixture (including gradation, asphalt aggregate ratio, temperature, etc) is the premise of good pavement performance of asphalt pavement, it is regarded the key of ensuring service life and pavement performance of road to ensure the quality of hot mixed asphalt mixture. This research is oriented at developing real-time quality control & monitoring system of asphalt mixture further on the basis of the established quality control system of mixing plant. The functions and operating principles of the system are introduced in this article.
