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.
cheap gravel for gardens light tower for sale in spain milling machine in philippinesHS polymer road sealant, is specifically for the actual situation of China's research and development of a crack sealant products. The product has strong adhesion, temperature resistance, tensile volume, easy construction and other characteristics: strong adhesion, protection and contact with a good adhesion; good temperature resistance for a temperature range of -30 ℃ a High elasticity, large amount of elongation, can withstand large displacement; easy construction, easy to heat the material, the viscosity is small, into the dense. China's vast north-south climate vary widely, different regions of the temperature corresponding to different materials, HS polymer road sealant ABC three specifications, high temperature, general type, low temperature type, for the majority of customers choose.Road Repair Machines
At present, the product is widely used in asphalt pavement cracks, cracks in the conservation of the seal, the road cover before the grass-roots cracks in the bridge, both ends of the bridge cement and asphalt pavement junction transition, bridge expansion joints, airport runway cement concrete pavement Seal processing. Construction instructions: the best construction temperature of the irrigation joints at 7 ~ 18 ℃: If the temperature below 4 ℃, the filling machine must be equipped with preheating equipment, the slotted parts of the preheat; if not at this temperature Preheat to fill the seam, will reduce the adhesion of the sealant. In the sealant heating temperature of 180 ℃ -210 ℃ between (not higher than 210 ℃), with the filling machine out of the pipe nozzle to seal the glue evenly into the tank, and dragged on both sides of the cracks into a certain width And the thickness of the seal; due to the sealant after cooling the volume will shrink, in order to achieve the desired effect of irrigation, can be taken back and forth twice the method. For example: eager to open the traffic, just filling the sealant to be sprinkled on its surface dry sand, and other sealants fully cooled, clean the road after the slag in the open traffic. The general cooling time is about 15 minutes, the specific time according to the temperature at that time to master.
