The difference between three roller shafts, sliding formwork and track machinery paving cement concrete pavement
The difference is that the unused method applies to different traffic conditions.Paving of track paverThe paving method of track paver has obvious trend that is replaced by slipform paver. Rail paver has the advantage of reversing the road surface, the disadvantage is that rail template overweight, rail template installation labor intensity.
Roller compacted concrete is made of asphalt paver or lime soil paver, and the compaction forming technology is a composite technology combining dry concrete technology with asphalt pavement paving technology. At present, there are still some problems that have not been solved thoroughly, such as cracks, segregation and partial early damage, the poor compactness of the slab bottom and the low dynamic flatness. Therefore, the majority of highway engineering technicians believe that RCC is only suitable for the cement concrete pavement below two or the lower layer of composite pavement.
Slipform mechanical pavingSlipform paving technology has become the highest quality, the fastest construction speed, the most modern high-tech equipment mature technology.Laying of three roller shaft unitsThe construction of the three roller shaft machine is more suitable for the construction of cement concrete pavement of highway two or three and four highway and county road.roller compacted concreteThe roller compacted concrete pavement is a kind of concrete pavement which is made of the main construction machinery of asphalt pavement, and the dry concrete with less water consumption is laid and rolled.
