Does the accelerated paving thickness increase or decrease when the paver is paving? In fact, during the paving process, the paver requires a constant speed, and the screed is floating on the paving material.
The manufacturer of the cold recycling machine believes that, in other words, the resultant force of the screed is zero at this time. Once accelerated, the speed increases, and the material required for screed paving does not increase in time per unit time (there is a process of machine reaction). As a result, the average distance traveled by the material decreases, so the thickness of the paved road surface decreases. At this time, when the speed stabilizes, the screed has the requirement to regain balance, The thickness will gradually increase to the original thickness.
In real construction, paving is related to speed, temperature, material mix ratio, and the rigor of construction.
The operating speed of the paver is determined by maintaining a uniform rotation of the conveying and distributing materials to determine the large paving speed. Regularly increase the traveling speed value, rammer value, material delivery value, and material separation value accordingly, so as to regularly increase and decrease them simultaneously. Large paving speeds cannot cause rapid rotation of the scraper and spiral, which can cause segregation of the paving surface.
Adjustment of scraper and spiral speed: According to the correlation between paving thickness, width, and paving speed, find the corresponding interface in the main controller, set it by 50%, and then adjust it according to the paving speed during the paving process.
During the paving process of the paver, it is necessary to be able to continuously pave and not stop at will to avoid affecting the flatness of the road surface. When an unexpected situation occurs and it is necessary to stop, the anti settlement lock of the paver's screed plate should be opened to prevent the screed plate from sinking. When starting again, the paver's screed plate should be opened to prevent the low temperature of the asphalt material in front of the screed plate from lifting the screed plate, increasing the paving thickness, and affecting the flatness of the road surface.
In terms of the operation of the paver, during the paving process, attention should also be paid to maintaining the continuity and stable speed of paving as much as possible. It is strictly prohibited to be fast and slow, minimize the number of stops, and prohibit the transport vehicle from colliding with the paver when reversing. If necessary, the flatness can be controlled by setting out and leveling on both sides, using the longitudinal slope meter of the longitudinal slope paver, and walking steel wires.
That's all about accelerating the paving thickness when paving with a paver. If you have any doubts or needs about this, please come to our website http://www.cifrimas.com Consult and understand!
