The seat design on Roadtec pavers allows the operator to quickly check material levels at the rear auger.
Paver operators must have the ability to quickly visually check the rear auger of their machine to make sure material levels are where they are supposed to be for a quality paving job. That is why Roadtec engineers designed the new pavers seats to slide out to the side in a straight line instead of swinging out on an arc.
The straight sideways movement of the seat results in a position that allows the operator excellent visibility down the side of the machine and also to the rear augers. It™s important to visually check augers because mix should always be halfway up on the augers over the entire width of the auger delivery system.
Augers should never be buried in mix at any point. Augers should never be raised too high because this could cause mix to push forward under the paver. If there™s too much or too little material around the auger, problems in the paved surface will result. Paving speed, flow gate settings, and feed sensor position regulate material flow.
Being able to easily see the augers allows the operator to monitor these variables and to deliver mix evenly across the augers and thus across the entire leading edge of the screed plate, which is a requirement for a segregation-free mat.
