Road Paver Machine Mixing Process

Strictly control the mixing temperature and exit temperature of the Road Paver Machine aggregate.

(1) The rubber particles should be inspected for quality before use and determined to meet the requirements.

(2) Rubber pellet heating temperature 190-200 ° C

(3) The Road Paver Machine control room monitors the amount of printing asphalt and various mineral materials and the mixing temperature, and regularly checks the metering and temperature of the materials.

(4) Stirring time is determined by trial mixing. All the aggregate particles must be wrapped with the asphalt binder, and the asphalt mixture is uniformly mixed, and then the rubber asphalt is added for 40s.

(5) When working on the Road Paver Machine, pay attention to visually check the uniformity of the mixture and analyze the anomalies in time. If the mixture has no whitening, blue smoke and segregation. If it is confirmed to be a quality problem, it should be disposed of as waste and corrected in time. Before the start of production, the personnel concerned should be familiar with the appearance characteristics of the various mixes used in the Road Paver Machine, which should be obtained by carefully observing the mix of the indoor test mix.

(6) After the end of each day, the total amount of stocks printed by the Road Paver Machine is used for total amount control. The grading of mineral materials was checked online by the amount of each bin and the results of each bin screening; the average construction gradation and the ratio of oil to stone were calculated and checked with the design results; the average thickness was calculated from the daily output, and the pavement design thickness was checked.

(7) Road Paver Machine discharge temperature is 170 ° C -185 ° C is appropriate, more than 190 ° C discarded.
