LTP1016H Hydraulic Pneumatic Tires Road Roller with CUMMINS engine 75kw

Pneumatic tire roller is a kind of compaction machinery which relies on the gravity of machinery itself and increases the compactness of working medium by static compaction of paving materials with specially designed pneumatic tires, which is widely used in the compaction operation of foundation layer, sub-foundation layer, filling and asphalt surface layer of various materials.

Unlike vibratory rollers, pneumatic tire rollers have not only vertical downward compaction force, but also horizontal compaction force along the direction of mechanical travel and transverse direction. These forces, together with the “kneading effect” of the rubber tires, produce excellent compaction results. Especially in the asphalt pavement compaction operation, its unique flexible compaction function can not be replaced by other compaction equipment, is the main machinery of asphalt mixture re-compaction, but also the construction of high-grade highways, airports, harbors, embankments, and industrial construction sites of the ideal compaction equipment.

How to choose a roller in actual compaction work?

General compaction consists of initial compaction, recompaction and final compaction. If the initial compaction can meet the density requirements, there is no need for re-compaction, but the practice are still keeping these three steps.

• Initial compaction is usually done with steel wheel rollers, but there will be pushover phenomenon, that is, the mixture on the front side of the drum is pressurized to move laterally, and cracks may occur after compaction. In practice, there are also used with pneumatic tire rollers for the initial pressure, but because of the high temperature during the initial pressure, the mixture is easy to adhere to the tires, and the traces left behind are not easy to remove, so pneumatic tire rollers for the re-pressing of the opportunity to be more.
• There are more chances for re-compaction to be operated by pneumatic tire rollers. One: pneumatic tire compaction is a kind of kneading compaction, compaction effect is good, and can remove the small cracks produced by the steel wheel compaction. Two: Rubber wheel compaction causes the gum paste formed by asphalt, mineral powder, and fine aggregate in the mix to float upward, making the upper surface tighter and more watertight.
• The final compaction is to remove the traces of the roller, in order to keep the road surface level, and it is a steel wheel roller.
