Description

TECHNICAL FIELD

[0001] The utility model relates to highway engineering measurement technical field especially relates to a kind of for asphalt pavement arching measurement device. BACKGROUND

[0002] With the development of transportation, asphalt pavement is increasingly widely used. However, under the action of various factors, arching phenomenon may occur in asphalt pavement. Arching of asphalt pavement refers to the upward bulging phenomenon of asphalt pavement under certain conditions. This phenomenon usually occurs on the surface or inside of asphalt pavement, causing unevenness of the road surface, and thus affecting traffic safety and driving comfort. The apparent characteristics of arching of asphalt pavement are generally road surface arching deformation, forming a transverse arching similar to "natural speed reduction zone", and the developed arching zone can penetrate the entire pavement.

[0003] Currently, the methods for measuring arching of asphalt pavement in engineering include visual inspection, flatness measurement and ultrasonic measurement. Visual inspection is a relatively simple method, which directly observes the flatness and morphology of the road surface by the human eye, and finds obvious bulging, cracking or deformation phenomenon. However, this method is highly subjective and relies heavily on the experience of the detector. For some slight arching conditions, the human eye may not be able to accurately detect, which may lead to missed detection, and thus potential pavement problems cannot be discovered in time. Flatness measurement usually uses a level or a ruler to measure the height difference of the road surface. Although this method can measure slight arching problems, the operation process is complicated. It is necessary to carefully place the measuring tool on the road surface and ensure the accuracy of the measurement, which requires a lot of time and manpower. In actual engineering, this method is low in efficiency and is not conducive to large-scale pavement detection. Ultrasonic measurement uses the characteristics of ultrasonic waves to measure the arching of the road surface. Although this method has high measurement accuracy, it has high measurement cost and is not easy to popularize due to its complicated operation. SUMMARY
