Research on Maintenance Equipment and Maintenance Technology of Steel Fiber Modified Asphalt Pavement with Microwave Heating
In this article, the 166TYHB road microwave maintenance vehicle was used as the main equipment, aiming at the investigation of the application characteristics of microwave healing technology on asphalt pavement and proving the effective of microwave heating technology in practice. The heating performance and healing behavior of steel fiber modified asphalt pavement under microwave irradiation were analyzed. The maintenance technology of asphalt pavement was designed and optimized, and the corresponding relationship between the maintenance effect of 800W microwave oven in the laboratory test and the maintenance effect of 90kW road maintenance vehicle in practical construction was established. The test results showed that with the curing of microwave irradiation, the steel fiber modified asphalt pavement presented an excellent healing performance, and the heating rate of the surface of asphalt pavement could reach as high as 26°C/min. Meanwhile, as there is no need to apply another raw materials during the maintenance stage, the Pavement Condition Index(PCI) of asphalt pavement could be improved to a high degree, which is much beneficial to maintain the comfortability of pavement.
