Description
Technical field
The present invention relates to a kind of highway pavement material test instrument, especially for the instrument that detects pitch mixed material cracking resistance.
Background technology
Bituminous pavement in the highway construction mainly adopts the asphalt making in basic unit, and compacting forms through the street roller tool.Asphalt is to mix and stir the road-making material that forms by the coarse aggregate of different-grain diameter, fine aggregate, filler by certain grating and asphaltic binder.The grating of pitch kind, bitumen content and various mineral aggregates in the asphalt all can have influence on the cracking resistance of asphalt, especially bituminous pavement is a kind of than the common damage form by semi-rigid type base influence generation reflection crack, it has a strong impact on the serviceable life of road, therefore before building the road surface on a large scale, just carry out the cracking property test and testing and the check of asphalt, determine the optimal material kind and the proportioning of asphalt, to reach best cracking resistance, be very important.But, in known technology, the cracking resistance pilot project has only been proposed in highway construction at present, still there are not ripe test standard and test apparatus.Reach the test and the check purpose of asphalt, utilize existing instrument and equipment such as Reciprocatory pressure testing machine, carry out displacement (strain) and load (stress) is tested the detection pitch mixed material cracking resistance, the composition structure of its bulk testing detecting instrument and operation are just quite complicated, and test sense environmental conditions instability, it is bigger influenced by human factor, data accuracy is poor, brings inconvenience to use.
Summary of the invention
The present invention is used to overcome the deficiencies in the prior art, provides a kind of simple in structure, and the test testing environment is stable, data are accurate, automaticity is high, be exclusively used in the test detecting instrument of pitch mixed material cracking resistance.
The present invention addresses the above problem the technical scheme that is adopted:
A kind of pitch mixed material cracking resistance tester, it is by environmental cabinet, hold-down support, the bonding platen, sliding panel, the sledge displacement load maintainer, the radial sensor, the rotation shaft coupling, servomotor is formed, in the case of environmental cabinet, be equiped with hold-down support, the bonding platen is housed on the hold-down support, the bonding platen is the company's of touching sliding panel movingly, sliding panel bottom load sledge displacement load maintainer, the sledge displacement load maintainer connects servomotor by the rotation shaft coupling, and on the tray joint shaft of rotation shaft coupling, be connected with the radial sensor, on the rotation shaft coupling lateral body bearing of bearing insert in environmental cabinet is housed, the servomotor load is in environmental cabinet lateral body outside.
Above-mentioned pitch mixed material cracking resistance tester, described sledge displacement load maintainer is to be connected to form by push-pull shaft and push-and-pull seat, push-pull shaft is the ball screw axle, the push-and-pull seat is shaped on screw and is meshing with each other into the screw mandrel screw with the ball screw of push-pull shaft and is connected, the push-and-pull seat is connected in the sliding panel bottom, and push-pull shaft connects the rotation shaft coupling and has the supporting base supporting that is contained on the environmental cabinet inner bottom plating to connect; Or adopting push-pull shaft is worm screw, and the push-and-pull seat is shaped on turbine and is meshing with each other into turbine and worm with the worm screw of push-pull shaft and is connected.
Above-mentioned pitch mixed material cracking resistance tester, described servomotor is the speed-regulating type servomotor, or is associated with the servomotor of reductor.
Above-mentioned pitch mixed material cracking resistance tester, described environmental cabinet be can regulating and controlling temperature can closed thermal environment case, the temperature controlling range of environmental cabinet is-25 ℃～60 ℃.
When the present invention tests, connect controller at radial signal of sensor line, controller connects servomotor and microcomputer respectively, and design the project indicator that test detects, produce the reflection crack process with regard to available test instrument by the basic unit's influence of facing the mountain of its environmental cabinet simulation bituminous road, with the pre-set environment temperature of environmental cabinet, in environmental cabinet, put into test specimen, by designing requirement operational computations machine, computing machine is given controller according to the instruction issue an order, controller control servomotor drives the sledge displacement load maintainer test specimen is added unloading, pressure in the radial sensor acquisition process of the test, shift value passes the signal in the controller, controller connect computing machine with data processing after, controller is issued in instruction be transferred to servomotor again, its operation control method adopts displacement (strain) control and load (stress) to control two kinds, carries out pitch mixed material cracking resistance test and detection.Utilize this test instrument to detect the cracking resistance index of asphalt by test, its cracking resistance is carried out rational evaluation, material mix proportion is carried out preferably, guiding construction, improve asphalt making quality, reduce asphalt pavement crack quantity,, improve the road service level to prolong road serviceable life.
Because the present invention designs and adopted technique scheme, existing pitch mixed material cracking resistance tester device one-piece construction and the complicated problem of operation have been solved effectively.Show through testing result on trial for several times, it compared with prior art, have simple in structure, the test sense environmental conditions is stable, has reduced artificial factor, and instrument performance is stable, test that to detect data accurate, the automaticity height, advantage such as easy to use is applicable to that the various pitch mixed material cracking resistances tests of constructing highway detect.
