Abstract

This application provides a method and system for improving the quality of foamed asphalt. The quality improving method includes: using the segmented centralized parameter bond graph method to establish a bond graph model of the piping system of the asphalt foaming device; The bond graph model is used to obtain the simulation model of the piping system of the asphalt foaming device; the user interface of the piping system of the asphalt foaming device is established, and the user interface is used to receive input parameters; the simulation model of the piping system of the asphalt foaming device communicates with its user interface, and the asphalt The simulation results of the simulation model of the piping system of the foaming device are displayed on the user interface; the time difference between asphalt and foaming water reaching the foaming chamber is obtained according to the simulation results; the time of spraying asphalt and the time of foaming water are respectively controlled according to the time difference. This application conducts online simulation of the dynamic characteristics of the piping system of the asphalt foaming device, and then controls the asphalt and foaming water to reach the foaming chamber at the same time according to the simulation results, so as to improve the quality of foamed asphalt.

Description

technical field [0001] The application belongs to the technical field of road construction machinery engineering, and in particular relates to a method and system for improving the quality of foamed asphalt. Background technique [0002] Since the 21st century, my country's road construction has entered a peak period, of which asphalt roads account for the vast majority. The design life of asphalt pavement in my country is generally 15-20 years. With the increase of road mileage and road traffic flow, the existing asphalt pavement is aging year by year, and most expressways have entered the maintenance period. About 12% of the asphalt pavement needs to be repaired and maintained every year, and the waste material of the old asphalt pavement is about 2.2 million tons, and this figure is growing at a rate of 15% every year. Highway construction and maintenance have aggravated energy consumption and environmental pollution, leading to increasingly intensified contradictions be...
