Brief introduction of tyre roller
The compacted asphalt mixture conforms to the requirements of compactness and smoothnessSelect reasonable roller combination method and rolling steps to achieve the best results. The asphalt mixture is compacted by a steel cylinder type static roller and a tire roller or a vibratory roller. The number of rollers is determined according to the production site.The compaction of asphalt mixture is carried out in three stages: initial pressure, compound pressure and final pressure (including molding). The roller is rolled at a slow and uniform speed.The initial pressure of asphalt mixture meets the following requirementsThe initial A. pressure roller soosai eng DD-110 in mixture paving after high temperature, and shall not have any time, hair crack, compaction temperature according to the consistency of asphalt, roller type, temperature paving layer thickness, mixture type is determined by the pressure test with test.B. roller is rolled from the outside to the center. The adjacent rolling zone should overlap with 1/3 - 1/2 wheel width. At last, the center part of the rolling road will be compressed at full amplitude. When the edge of the baffle, kerb, shoulder and other files, should be close to the file roller. When the edge without retaining, can mix the edge rake rake slightly high, then the outer wheel roller rolling out 10cm above the edge.
A tire roller is a machine operated by a plurality of pneumatic tyres for the road. The roller of tyre roller adopts pneumatic tyres, usually 3~5 front wheels and 4~6 rear wheels. If the change of inflation pressure can change the ground pressure, the range of pressure regulation is 0.11 ~ 1.05 mpa.The tire roller adopts hydraulic, hydraulic or mechanical transmission system, single shaft or full axle drive, wide base tire, articulated frame structure, three point support. Compaction process has the role of rubbing, so that the compaction layer particles are not damaged and embedded, homogeneous and dense. Good maneuverability, fast speed (up to 25 km / h).
