Impact rolling is the latest development of geotechnical compaction technology. The impact roller is driven by the non-circular wheel of the tractor. The radius of the polygon roller produces a bit drop and the kinetic energy of the running. The continuous pressing of the earth and stone material along the ground is rubbing, Amplitude, low frequency impact compaction principle. At present, 25KJ triangular two-wheel impact roller use the most, the double static weight 12t, driving the best speed of 12km / h, on the ground to produce a concentrated impact of 200 ~ 250t, equivalent to 1111 ~ 1543kPa. This high-energy impact force periodically impact the ground, resulting in a strong shock wave,Road Repair Machines down with the propagation characteristics of seismic waves, resulting in the impact of rolling function to achieve heavy weight hit the actual work, the depth of the underground deep density can continue to increase, to meet Heavy-duty standard 90% of the degree of compaction of the effective compaction thickness of different soil and stone properties of different physical properties of 1.0 ~ 1.5m, than the existing vibration compaction machinery has a better compaction effect, so that the stamping of the earth and stone filler closer to the elastic state , Showing the technical advantages to overcome the hidden dangers of earth and rock roadbed.
Cement spreader: the scene of cold regeneration milling old asphalt mixture, the old asphalt can not afford the role of adhesive, need to add inorganic binder (cement, lime, fly ash) or organic binder (emulsified asphalt ) After mixing, rolling only with bearing capacity. The cement can spread the cement evenly to the road in a prescribed amount. The technical difficulty in developing a cement spreader is that the amount of cement must be accurate. And the amount of cloth and the speed, the amount of cement measured rotor speed. This is actually a continuous feeding problem of cement, continuous measurement of the automatic control.
Asphalt sprinkler: Asphalt sprinkler can sprinkle hot asphalt, but also sprinkle emulsified asphalt. The measurement of asphalt is related to the speed of the vehicle and the speed of the asphalt pump. It is also a continuous feeding of liquid (asphalt) material, continuous measurement of automatic control problems.
