Description
Technical field
The utility model relates to porous pavement voidage measuring technology, particularly a kind of porous pavement voidage test data collector.
Background technology
Voidage characterizes the very important index of Pavement Condition, and the seepage of water especially for porous pavement plays decisive role, affects the water stability on road surface further, in addition, closely related with the permanance on road surface, applicability and economy.Science measures road surface voidage accurately, has important directive significance for the water permeability on correct evaluation road surface, stability, fatigue resistance, rutting resistance and permanance.
At present, the method of mix hole gap rate is calculated in " highway engineering pitch and Asphalt Mixture Experiment code " (JTG E20-2011), only relate to the theoretical maximum specific density of vacuum method and solvent method mensuration asphalt, be indirect method and calculate compound porosity, there is certain error.It is worthy of note, these two kinds of methods all Shortcomings: solvent method is dissolved by asphalt membrane by triclene, asphalt membrane after dissolving will enter in mineral aggregate clearance gap, there is compound actual volume to diminish, maximum theory density becomes large problem, and trichloroethylene solvent harm operator ' s health, contaminated environment.Vacuum method is difficult to the space of remaining silent processing loose asphalt completely, causes result inaccurate.Generally prove that vacuum method is not suitable for measuring the theoretical maximum specific density of modified asphalt mixture both at home and abroad.Meanwhile, these two kinds of methods all belong to and damage detection, need core boring sampling, destroy pavement structure.
Utility model content
The utility model provides a kind of porous pavement voidage test data collector for solving in known technology the technical matters that exists, and the data adopting this device to gather are true and reliable, make the result of calculation of voidage more accurate.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of porous pavement voidage test data collector, comprises the x-ray image acquisition system, image processing apparatus and the image memory device that are connected successively; Described x-ray image acquisition system is provided with filming apparatus; Described image processing apparatus is provided with the image intensifier be connected with described filming apparatus, the image digitizing device be connected with described image intensifier; Described image digitizing device is connected with described image memory device, and described image memory device is provided with USB port; Described x-ray image acquisition system, described image processing apparatus and described image memory device are controlled by gauge tap respectively.
Described x-ray image acquisition system is also provided with coverage regulating device and shooting depth adjustment.
The advantage that the utility model has and good effect are:
1) adopt X-ray through-transmission technique and image processing techniques, reach the effect of real simulation, it is high that it gathers image resolution ratio, clear picture.
2) be provided with coverage and shooting depth adjustment, scope and the degree of depth of data acquisition can be regulated as required.
3) belong to Non-Destructive Testing, without the need to core boring sampling, can not pavement structure be destroyed.
4) simple to operate, accuracy is high, and porous pavement all can use this device, suitable environment and scope wide.
5) without the need to using special negative-pressure container or triclene class chemical solvent, environmental pollution is not had.
6) image of x-ray image acquisition system collection can be changed into computer and the accessible form of printer by image digitizing device, makes the processing mode of image become very extensive.
In sum, the utility model constructability onsite application, data are true and reliable, do not damage pavement structure, and it is convenient to realize, and practical, result of use is good, are convenient to promote.
