Abstract:Relying on Fuji Highway, a system dynamics model of vibration wheel of vibratory roller compressed materials was established on the basis of mass spring damping coupling model, and the real time analysis and detection system of vibration compaction of asphalt mixture was developed. Based on the field measurement of temperature distribution of asphalt mixture during paving and rolling process, the relational model of compactness vibration acceleration temperature of AC 20, AC 25 and ATB 25 asphalt mixture was established. The results show that the vertical acceleration of vibration wheel of vibratory roller is proportional to the stiffness of the compressed asphalt material and inversely proportional to the damping. The compactness of asphalt mixtures shows quite good linear relationship with vibration acceleration virtual value. The correlation coefficient square of the compactness vibration acceleration temperature relational model of AC 25 is 099, and the difference between the calculated value and the measured value of compactness is -30%14%.
