Bituminous mixture admixture feeding amount monitoring device and use method

Abstract

The invention relates to an asphalt mixture admixture feeding amount monitoring device and a using method, and belongs to the technical field of asphalt mixtures, the asphalt mixture admixture feeding amount monitoring device comprises a feeding device, a conveying pipe and a monitoring device, the monitoring device is installed on the conveying pipe, the feeding device is communicated with the conveying pipe, the monitoring device comprises a fixed monitoring device and a movable monitoring device, and the fixed monitoring device is communicated with the conveying pipe. The fixed monitoring device comprises a fixed column and an infrared laser distance measuring sensor, the infrared laser distance measuring sensor is fixed to the conveying pipe through the fixed column, three monitoring holes are formed in the conveying pipe, and the infrared laser distance measuring sensor right faces the monitoring holes. And the construction quality problems such as early damage of an asphalt pavement and the like caused by the reduction of pavement performance of the asphalt mixture due to missed feeding or insufficient feeding amount caused by manual operation errors or mechanical faults can be avoided.

Description

technical field [0001] The invention belongs to the technical field of asphalt mixture, and more specifically relates to a device for monitoring the amount of an external admixture in asphalt mixture and a use method thereof. Background technique [0002] With the rapid development of my country's highway construction, asphalt pavement has been widely used and recognized, because it has its own unique advantages compared with other pavements, such as asphalt pavement has high strength, comfortable driving, small dust, low vibration and noise , easy recycling and regeneration, etc., so it becomes the first choice for road pavement applications. In recent years, under the influence of comprehensive factors such as increasing traffic volume, increasing number of heavy-duty vehicles and deteriorating natural environment, the asphalt pavement of highways has been damaged to varying degrees, especially on special road sections such as logistics distribution, level intersections, an...

AI Technical Summary

Problems solved by technology

[0004] Therefore, in view of the problem that the dosage of external admixtures is often insufficient in the current highway asphalt pavement construction process, the development of a device and method for monitoring the dosage of external admixtures in asphalt mixtures will play an important role in further improving the quality of highway asphalt pavement and practical significance
