In many views, the multi-function of the device must be very good, with complete applications and wide application fields, but not all devices are suitable for multi-function. Today, Jinan paver rental manufacturer will come to share with you the multi-functional selection of pavers.
1. Different materials require different ground adhesion of pavers.
Paving quality requirements: a good asphalt surface course requires a high level of screed and automatic leveling system of the paver, and the components are precise. Once the base course is paved with stable materials, the screed and feeding system will have great wear, which will seriously affect the construction quality of the surface course.
The load of pavers varies greatly in different material paving operations: the load of paving base material is generally 30%~40% higher than that of asphalt material, and the wear of machinery in all aspects is much more serious in unit time, causing great damage to important mechanical parts such as engine, screed, material conveying mechanism, and reducing the effective service life of machinery, which is uneconomical.
To sum up, for the paving of municipal roads, the selection of pavers should meet the requirements of high paving accuracy, flexibility of use and economy, and should not pursue the multi-function operation of pavers too much.
2. Scientific setting of paving width and paving thickness
The selection of the width and thickness of the asphalt paver should weigh various factors and be determined comprehensively, including the actual needs of the project, the production capacity of the asphalt station, and the quality requirements of the paving. The paving thickness of the paver is generally between 0 and 300 mm, which can fully meet the construction requirements, and the configuration tends to be consistent. The greater the thickness, the smaller the pre-compaction, and the construction flatness and compaction cannot be guaranteed. It is not allowed to blindly pursue the paving width. It is a mistake to improve the flatness with full width paving, for the following reasons:
Due to the large paving width and the long distance between the spiral distributor and the mixture, the segregation of coarse and fine materials is inevitable, which affects the pavement quality and causes early damage. Wide paving, the surface looks flat, but the compactness of the middle and the edge is different, and the transverse flatness cannot be guaranteed after rolling by the roller.
