Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement detection, in particular to an asphalt pavement deformation resistance detection device. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. This type of pavement structure belongs to the category of flexible pavement. In addition to flexible materials, its base layer can also use rigid cement concrete or semi-rigid hydraulic materials. The use of asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving 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] However, in the prior art, when testing the deformation resistance of asphalt pavement, a hydraulic telescopic rod or a driving motor is generally used to drive a clamping plate to detect the ground. Such high thrust and speed can easily cause damage to the connection, so a buffering structure is required for connection. The asphalt pavement deformation resistance detection device cannot be adjusted to detect pavements of different heights, which leads to certain limitations in the use of the device.
