[0013] Compared with the prior art, the present invention provides a device for detecting the uniformity of aggregate distribution in asphalt pavement with a protective structure, which has the following advantages:

[0014] 1. This asphalt pavement aggregate distribution uniformity testing device with a protective structure, by designing a clamping plate at the end of the connecting strip and a sliding rod and a clamping block at the end of the clamping plate, allows the clamp head to be engaged inside the first clamping groove, enabling the installation and use of the wire and the testing head. After installation, the deformation of the connecting strip engages the clamping plate and the clamping block inside the second clamping groove. At this time, the elastic deformation of the second spring and the first spring causes the clamping block to slide on the outer surface of the sliding rod, so that the clamping block and the clamping plate are tightly pressed inside the second clamping groove, facilitating the installation of the connecting strip. When the wire is tightened, it is not easy to loosen or have poor contact. This solves the problem that the wire is easily tightened without care during use, resulting in the clamp head not being securely engaged, which can easily lead to detachment or poor contact, affecting the use.

[0015] 2. This asphalt pavement aggregate distribution uniformity testing device with a protective structure, by designing a winding body inside the placement groove, allows the clamp head to be disassembled from the first clamp groove after use. The wire is wound around the outer surface of the winding body and placed inside the placement groove. The end of the wire is clamped and installed through the groove. After closing, the protective cover is closed on the surface of the placement groove, and the knob is turned to fix the protective cover. At this time, it is easy to protect the wire through the protective cover and the placement groove, and it is not easy to be exposed to the outside world and damaged. This solves the problem that it is not easy to wind up and protect the wire after use, and the wire is easily damaged when exposed to the outside world.

[0016] 3. This asphalt pavement aggregate distribution uniformity testing device with a protective structure facilitates stable control of the compaction block via a sliding rod, which is beneficial for compaction installation. The first spring and sliding rod ensure an elastic, tight connection between the compaction block and the clamping plate, facilitating compaction and control. Attached Figure Description
