In order to ensure the safety and durability of asphalt pavement, it is necessary to conduct regular inspection and maintenance of asphalt pavement.

[0003] For example, an asphalt content detection device for asphalt pavement with the authorization announcement number "CN215339042U" completes the sampling of asphalt by entering the interior of the collection box through the collection hole. After the collection box is taken out, the sampled asphalt in the collection box is poured into the asphalt detector to complete the asphalt detection work, thereby improving the detection efficiency. However, the device needs to remove the limit bolt from the limit hole, release the restriction on the fixing rod, and then pull the fixing rod out of the fixing hole, and the connecting rod falls off from the mounting port of the connecting block before the collection box can be disassembled, which increases the workload of the operator and reduces the working efficiency of the device. After the device completes the collection through the collection box, it lacks sealing, which can easily cause the loss of detection samples, resulting in inaccurate detection effect experimental data.
