Construction Process of Grinding Old Asphalt Concrete Surface

 Milling process, first as required to determine the location of the old road, width, depth. Milling machine in the starting point along the side in place, put the position, according to the height of the dump truck compartment height adjustment of the mouth height position. The dump truck is parked in front of the milling machine waiting to receive the milling material. Start the milling machine, by the two technical staff to operate the left and right sides of the milling depth control

Instrument, according to the requirements of a good depth. When the depth is adjusted, the milling operation is performed by the operator. During the milling process, the front of the dump truck by hand to move forward, so as not to milling machine out of the conveyor belt hit the car after the dump truck, while observing whether the car is full, command milling machine to stop the output milling material. Command the next dump truck in place to receive milling material. At the same time command milling machine U-turn or reverse work. During the milling process, the two technicians should follow the milling machine and observe the milling effect. If the milling depth is not correct or the milling is not complete, the milling depth will be adjusted in time. If the milling plane is uneven, Deep groove situation, timely inspection milling cutter head, whether damaged, timely replacement, so as not to affect the milling effect. During the milling process, the waterwheel is on standby at any time because the milling needs to be depletedRoad Repair Equipment - Doan Machinery

The amount of water, the need for timely water. Milling is done in sub-form. Requires a milling molding, a thorough old Lek Green concrete pavement clean, not left corners, or two milling interface interface is not good, there is missing old asphalt concrete. For those who are not transported to the dump truck on the milling material, piled to the road, to promptly manual cleaning, so as not to affect the future traffic.

The stacking site should be flattened and compacted. Planning scope, clear signs. Milling and gripping sand mixing method. Milling and Klink Sand mixing using mechanical mixing. That is, the way the loader is combined with the excavator, and one site is packed with a loader and two excavators. Place the milling material and the Klink Sand stacking position closer to the loader Shovel together, with the excavator twice turned to mix. If the mixing effect is not good, need to use the excavator again to turn to mix until the requirements so far. Prevent dust pollution. To timely add water to the milling machine, to reduce the generation of dust. To prevent contamination of milling material. Do not cut the milling material in the river, the roadside, in a timely manner, transported to the designated location. To check the milling effect in a timely manner, check the milling width, depth, and milling position. Check the stacking position of the milling material to check whether the stacking is in compliance with the requirements. Whether it is a mess. For mixing a good mix of materials to be timely sampling experiments to guide the construction of mixing.
