Description

Technical Field

[0001] This utility model belongs to the field of paving thickness detection technology, and in particular relates to an instrument for detecting the thickness of road asphalt paving. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in the form of liquid or semi-solid petroleum. Asphalt is a widely used pavement structural binder in road engineering. When mixed with mineral materials of different compositions in a certain proportion, it can be used to build asphalt pavements with different structures. It is widely used on highways.

[0003] During the construction of highways, especially those in mountainous areas, the inconsistent thickness of asphalt paving caused by manually operated pavers affects the overall quality of the road surface and leads to problems such as varying stress on surfaces of different thicknesses. Therefore, after the asphalt pavement is laid, its thickness needs to be measured. Current technologies for measuring asphalt paving thickness use steel rulers or steel rulers with screwdrivers, but these traditional techniques are time-consuming, labor-intensive, and produce inaccurate readings, resulting in unsatisfactory asphalt paving thickness. Utility Model Content
