Theoretical Model and Experimental Study of Paving Parameters Influencing Mixture Compactness

Abstract

In order to make a deep research on the effect of asphalt mixture paver’s working parameters on paving material’s compactness, the mathematical model was established among vibrators structural parameters, operating parameters and paving quality parameters based on full-scale test and theoretical derivation. Furthermore, the relationship was determined by vibrator’s width, vibration frequency, paving speed and material’s compactness. According to Matlab software analysis, the range of paving speed was obtained under the optimum paving compactness. For typical asphalt mixture pavers, when the vibrators frequency is less than 25Hz and vibrators width is 0.04m, the operation speed cannot exceed 5m/min.
