Paving Of The Running Track Paver Machine Test Section

When paving the stability test section, in terms of the paving process, it is mainly to summarize and determine the exact technical parameters to guide the formal construction: such as the initial paving thickness, paving initial elevation, paving The looseness factor, the grading value of the screed, the screw conveyor and the scraper level parameters, and the optimum travel speed of the paver. Under normal circumstances, it is advisable to spread 100~150 m in the test section. Running Track Paver Machine

(1) Determine the thickness of the initial paving pad: the thickness of the pad is equal to the thickness of the loose pad. The pad is made of 0.5 m long hardwood, and each paver is padded with 4 pads in front. Running Track Paver Machine

(2) Determination of the initial elevation angle of the paving: After paving for 5 m, the thickness of the paving is measured, and the elevation angle value and the measured thickness value are compared to determine the elevation angle and the paving thickness. Calculation parameters between.

(3) Determination of paving looseness coefficient: Rolling the stabilized layer of the paving to the specified degree of compaction, measuring the actual paving thickness, using the actual paving thickness and the unrolled paving thickness For comparison, the paving looseness factor is obtained.

(4) Determination of screed camber parameters: The level of road pavement completed by paving is measured by a water level meter. If the requirements are not met, the screed degree is adjusted.

(5) Determination of the optimum driving speed of the paver: Under normal circumstances, the driving speed of the paver is 2 m/min, and it should be adjusted according to the actual situation of the paving. Running Track Paver Machine

(6) Adjustment of the screw conveyor and the scraper plate leveler: During the paving process, adjust the level sensor of the screw conveyor and the scraper to ensure that the mixing material before the screed is continuous and uniform.
