PTJ-120 Sprayer Machine The vibration frequency of the screed is about 55Hi. The amplitude of the screed should be in the range of 0.4-0.6. The static pressure should be taken in the range of 9-15 kPa. In order to make the PTJ-120 Sprayer Machine working device interact well with the RCC mixture, during the pre-paving test, the parameters of the RCC mixture (including consistency) and the working parameters of the PTJ-120 Sprayer Machine can be appropriately adjusted Small adjustments are based on the principle of good final road surface.

When determining the paving speed V, observe and test the speed stability of the PTJ-120 Sprayer Machine at low speed. If the speed is unstable, the paving speed should be appropriately increased. Experience has shown that when the PTJ-120 Sprayer Machine works at a speed lower than 0.5m / min for a long time, the PTJ-120 Sprayer Machine may "crawl", unstable paving speed, and overheating of the engine. In addition, when determining the paving speed, consideration should be given to whether it is matched with mixing equipment and transportation equipment, so as to prevent the paving machine from stopping during the paving process and affecting the smoothness of the road surface.

Before paving, check whether the subgrade evenness meets the requirements to prevent the subgrade unevenness from reflecting to the road surface. Subgrade unevenness is well controlled within 8-3m ruler. From the perspective of ensuring good flatness of the pavement, it is recommended to use high-density asphalt PTJ-120 Sprayer Machine to pave the base layer in the construction of the base layer, so that the base layer has better flatness and sufficient strength. Before paving, the roadbed should be cleaned and sprinkled to make it fully wet, so as to prevent the roadbed from absorbing the RCC water, which will cause the water content of the mixture to decrease and affect the pulping and compaction of the RCC road.

The paving width should not exceed 8m, and the recommended paving width is 6m. Because when the paving width is large, the segregation of the aggregate during the process of conveying the RCC mixture from the center to both sides is also large.
