A fixed datum line, paver pave according to datum line height.This method is known as absolute standard control paving thickness method.
Since there are errors for the upright bar height that is manually arranged in paving process, or since the generation of pulling force deficiency wire its own gravity is scratched
Degree, will lead to paving thickness off-design value.
Equalizer bar method:Equalizer bar method includes the types such as mechanical contact floating equilibrium beam and non-contact balance beam.Wherein machine
Tool contact floating equilibrium beam carries out automatically controlling paving thickness by the height difference of front and back tie-beam, in asphalt pavement construction,
Its front longeron piston shoes becomes easily infected by pitch, and rear portion longeron traveling wheel is easy to generate cut in loose laying, can bring the thickness that paves
Degree control error;Non-contact balance beam is the difference control paving thickness of the distance measured using the sensor of beam front and back end, in reality
In the construction of border, since basal plane out-of-flatness before paving or equalizer bar rear end measuring point such as are interfered at the factors, paving thickness is also brought along
Control error.
Currently, the method for measuring paving thickness mainly has nondestructive determination and drill rod insertion.Nondestructive determination is applied
The detection methods such as Ground Penetrating Radar, ultrasonic wave are detected the road surface thickness after compaction moulding.Since this kind of detection method is usual
For vehicular, be not suitable for measuring road surface pine overlay thickness.In the operation of actually detected loose overlay thickness, continue to use substantially traditional
Drill rod insertion, drill rod are inserted into ground surface material, are measured with ruler and are obtained thickness value.This method detection speed is slow, reads number
It is low according to precision, it is unfavorable for paving thickness and accurately controls.
