The Measurement of Thickness and Model Prediction of Hot Asphalt Mixture in the Rolling Compacting Process

Abstract:

The thickness test and models prediction methods and rheological deformation theory have an important impact on quality control in the process of hot asphalt mixture field rolling compaction. DSL30 leveling instrument are used to measure the thickness in the process of hot asphalt mixture. Pt100 and Paperless Recorder are joined to test the temperature field and results of compaction thickness and temperature changes are obtained, and the model is established for mixture rheological deformation theory and compaction thickness prediction. The results shows that: by using the thickness and temperature field test methods, relevant data of hot asphalt mixture can be gained accurately, viscoplastic rheological theory correctly reflects its deformation behavior and the thickness forecast model can efficiently show the mixture layer. In this way, new methods are provided for the asphalt pavement quality control, rheological theory and temperature fields testing.
