Embodiment
Bituminous pavement measurer for thickness, by handrail 1, inserted link 2, scale bar 3, guide cylinder 4, support 5, contact plate 6, hold-down nut 7 forms.In the utility model, inserted link 2 and contact plate 6 adopt teflon plate material, the good characteristics such as this material has high-low temperature resistant (-192 DEG C-260 DEG C), corrosion-resistant, highly to lubricate, do not adhere to, nonhazardous, in assurance device with Asphalt Contactor face place not by asphalt adhesive, without the need to cleaning, improve detection speed and precision.Other material adopts stainless steel, ensures to possess enough rigidity.Scale bar 3 arranges scale mark, requires clear scales, scale division value is 0.5mm.Scale bar 3 lower end adopt screw type, guarantee to be fastenedly connected with inserted link 2 and scale bar 3 and inserted link 2 on the same axis.
During use, first carry out reference point demarcation.The support 5 of device is placed on the glass plate of one piece of flat smooth.Connect guide cylinder 4, support 5 and hold-down nut 7, inserted link 2 and scale bar 3 are passed guide cylinder 4 and support 5, makes to contact with each other with glass plate bottom its inserted link 2.Rotating the guide cylinder 4 that hangs down makes the 0mm place of its coboundary line and scale bar 3 overlap, then rotary fixing screw mother 7 is fixed on support 5, and using this scale mark as datum line, the datum line of assurance device is consistent.So far reference point is demarcated complete, may be used for on-the-spot bituminous pavement Thickness sensitivity.
When working-yard is detected, after asphalt paver paves, Stochastic choice dbullioscope loose laying depth, is placed on the asphalt mat paved by the device demarcated, and device contact plate 6 is contacted with asphalt mat.Again inserted link 2 and scale bar 3 are passed through guide cylinder 4 and support 5, hold handrail 1 slowly at the uniform velocity to exert oneself downward vertically, bottom the asphalt mat being inserted into high temperature, with the position that inserted link 2 no longer sinks, be defined as the brea bed (containing adhesion coating) that being inserted to mats formation rolls, total for inserted link 2 submergence depth is defined as the loose laying depth h of brea bed, by scale bar 3 quick and precisely reading.Detect roll after brea bed road surface thickness method of operating and step the same.
