Description

Technical Field

[0001] The utility model relates to an asphalt pavement, in particular to an asphalt pavement compaction detection device. Background Art

[0002] Asphalt pavement refers to various types of pavement that are paved by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] Asphalt pavement has to withstand the repeated effects of vehicle loads and the long-term impact of environmental factors during use. Therefore, asphalt concrete must have a certain bearing capacity while also having good durability against the effects of natural factors. Therefore, the pavement needs to be compacted during asphalt pavement construction to ensure the strength of the pavement. After compaction, compaction testing is required, so an asphalt pavement compaction testing device is needed.

[0004] The existing asphalt pavement compaction detection device uses a pressure sensor to detect the sample material of the asphalt pavement, but the flatness of the asphalt material cannot be guaranteed when sampling the asphalt material. During the pressure detection, the unevenness of the asphalt material will affect the detected pressure value, resulting in inaccurate detection. Utility Model Content
