Description

(1) Technical field [0001] The invention relates to a rut detection technology, in particular to a detection instrument for automatically detecting road ruts and a detection method thereof. (2) Technical background [0002] With the rapid development of my country's transportation, accurate and timely detection of road damage has become an increasingly prominent problem. As one of the main disease forms of asphalt pavement in our country, rutting seriously affects driving safety and transportation economy. Rutting detection and evaluation is one of the important basis for determining the maintenance plan, and it is also an indispensable technical content for long-term monitoring of the road surface. Most of the current rutting detection in our country adopts manual methods, using a ruler as a detection tool, and using manual direct measurement. The means are backward and extremely unsuitable for the operating environment of modern road traffic. At the same time, due to the...
