Research On Vibratory Roller Compaction Real-tima Continuous Monitoring Technology

Due to the constant progress of the highway,highway of quality problem increasingly prominent,has received the widespread attention of social group.Compactibility weak cause road surface early destruction of a key factor.Compaction task is to make the road base and road surface and a key step to connect all the building materials,with the help of a scientific and efficient compaction degree measure method is a key way to control.This paper in reference to our country and foreign country to explore the results of compaction degree measure method is the premise of explore on the accessory type track continuous compaction degree test system to measure the level of compaction degree,it is to compare the characteristics of convenient,efficient,and can accurately judge the degree of compaction,holistic uninterrupted inspection,help to carry out the compaction quality control.With the aid of theoretical research and the relevant practice,developed a vehicle type compaction test system framework of;determine the model selection of the sensor and signal acquisition instrument,as well as the selection of their performance parameters,data signal analysis and processing technology.Based on application system calibration test,vibration test equipment,realize the vehicle type compaction uninterrupted inspection system of research and development.Through the test on the spot test the application system is scientific.This paper explored based on MATLAB/SIMULINK simulation model of vibration road equipment,relying on the theory of inquiry found that the degree of compaction and the relationship between the vibration frequency,higher than both.Combined with field test set up three kinds of gravel soil compaction of soil compaction and vibration acceleration RMS and harmonic acceleration than the relationship between the expression.With the help of regression equations and inquiry found that the degree of compaction RMS building materials in the connection between the fine grain content.Thesis explore results can directly use to highway base compaction,compaction task more efficient,and can make reduce the burden of compaction task,helps to control level of compaction.In terms of security level of compaction is of crucial importance.In addition,the paper explore results can will translate into more products,has important significance in the field of highway construction project.
