Study On Compaction Degree Of Asphalt Pavement Continuous Detection System

Asphalt pavement construction technology is the ultimate guarantee of compaction is qualified.Pavement continuous test system away from the traditional compaction test when the tedious manual operation process,the acceleration sensor and detector installed directly on the compaction compaction degree of asphalt pavement continuous inspection can do in the true sense of the process control,seamless,no blind detection,the improvement of pavement compaction quality has important significance.This article analysis the deficiency of the traditional compaction test method and the compaction degree is insufficient on the harmful effects.Theoretical analysis of the principle of automatic detection,compaction degree determines the add speed to vibration compaction process to characterization of asphalt roadbed compaction degree.In suzhou city,anhui province see xu si county section of highway asphalt pavement paving for experimental basis,collection construction of vibratory roller vibration acceleration signal and pavement temperature,put forward the signal filtering,segmentation,IIR filter and technical processing methods,such as through the measured data and road compaction test results analysis to determine the pressure real-time vibration compaction degree of asphalt pavement and the relationship between vibration acceleration and provide technical support for continuous detection of asphalt pavement.Combined with the functional requirements,Through the technical analysis to choose the system hardware DH5902 acquisition card,ICP acceleration sensors,temperature sensors,PT-100 GPS antenna module and other hardware equipment.Combined with field test data analysis,to determine the hardware installation method.Using LabVIEW virtual instrument software development platform,to compaction equation set up process for system operation process main frame,write the compaction test system software programs in a row,the asphalt compaction test system interface design,program block diagram,realizes the real-time data acquisition,analysis,display,storage,and other functions.Continuous compaction degree detection system in sixu highway pavement· marking K19 + 795-830 period of facing the construction site test,system can realize the collection,analysis,display,storage,and other functions.Through field measured compaction test data and systematic analysis of the compaction degree of data analysis,the system can accurately detect the road when the degree of compaction,the construction operation side,the relationship between the third chapter compaction analysis accuracy.
