Description

Technical Field

[0001] The utility model mainly relates to the technical field of road construction, in particular to a road surface anti-skid thin layer anti-stripping detection device. Background Art

[0002] Road usually refers to a general term for various roads that serve land transportation and are used by various motor vehicles, human and animal-drawn vehicles, pack animals and pedestrians. Roads are divided into urban roads, highways, factory and mining roads, rural roads, forest roads, etc. according to their use. Urban expressways and highways are special roads for cars with controlled traffic and high speeds. Road engineering refers to the entire process of planning, design, construction, maintenance and management with roads as the object, as well as the engineering entities involved.

[0003] The anti-skid performance of the pavement is an important indicator to characterize the road safety performance. In order to improve the anti-skid performance of the pavement, a sintered bauxite high-anti-skid pavement structure and a pavement anti-skid thin layer technology have been proposed, which can greatly improve the anti-skid performance of the old road pavement and have a good application effect. However, during the use of the pavement anti-skid thin layer, due to the repeated action of vehicle loads, the aggregate may be peeled off from the binder, thereby reducing the anti-skid performance of the pavement anti-skid thin layer and shortening its service life. Therefore, it is necessary to scientifically test and evaluate the anti-stripping ability of the aggregate on the pavement. Among the existing detection devices, for example, the application number 202111645075.1 The technical structure includes: a bracket supported on the anti-skid thin layer of the road surface, a rotating rod rotatably installed on the bracket, a weight connected to the end of the rotating rod, a measuring tool placed on the anti-skid thin layer of the road surface, the measuring tool is clamped at the bottom of the bracket, and the measuring tool is provided with an inclined load-bearing plate corresponding to the weight. It mainly simulates vehicle load and checks the spalling of aggregate after applying a certain load. However, the weight of the weight is constant, and the mechanical energy acting on the load plate is the same each time and cannot be changed, which makes the test data inaccurate. In addition, the weight needs to be manually rotated each time, which is time-consuming and labor-intensive and very inconvenient. Utility Model Content
