Optionally, the depth of the pot hole is 7 cm to 13 cm.
Through adopting above-mentioned technical scheme, the pothole is provided with the degree of depth of multiple difference, provides the experimental condition that more is close true road conditions for the vehicle performance test, and sets up the pothole that the degree of depth is different on same section pothole experimental road way, and the car can collect more experimental data after once the road.
Optionally, the filling thickness of the asphalt layer is 6 cm to 9 cm.
Through adopting above-mentioned technical scheme, according to the needs of actual construction, select different pitch layer packing height, can make the pitch layer carry out appropriate protection to the pothole, and play effective reinforcement restriction effect to the band steel ring in the pothole.
In summary, the present application includes at least one of the following beneficial technical effects:
1. by arranging the pot holes and the embedded flat steel belt rings on the pot-hole test road, the automobile can carry out test tests on the pot-hole test road; and when the pothole test road is constructed, the machinery is used for paving the asphalt concrete to ensure the compactness and the flatness of the asphalt concrete, the construction efficiency is effectively improved, then the open hole position is measured and determined on the paved road main body, and the position precision of the pothole is also ensured.
2. Through set up the locating hole on the band steel ring, during the construction, the mounting hole is seted up in the road main part to the position that corresponds the locating hole of band steel ring, wears to establish the crab-bolt and fixes band steel ring and road main part together, and fixed knot constructs simply, connects firmly effectively, has reduceed the construction degree of difficulty.

Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses a pothole test road, and referring to fig. 1 and 2, the pothole test road comprises a road main body 1, a pothole 2, a flat steel belt ring 3, an anchor bolt 4 and an asphalt layer 5, wherein the road main body 1 is paved by asphalt concrete for automobile test running, the potholes 2 are unevenly distributed on the road main body 1, and when the test is carried out, an automobile is controlled to run through the pothole 2 for testing; the diameter of the pot hole 2 is set to be 20 cm to 40 cm according to the test requirement, and the depth of the pot hole 2 can be set to be 7 cm to 13 cm.
The flat steel belt ring 3 is embedded in the pot hole 2, so that the size requirement of the pot hole 2 required by testing is accurately guaranteed while the corner collapse of the pot hole 2 is prevented. Flat steel belt ring 3 uses the steel sheet bending weld to form, and the locating hole 31 of equipartition is seted up to flat steel belt ring 3's side, and mounting hole 11 is seted up to corresponding position on the road main part 1, inserts crab-bolt 4 and fixes, and crab-bolt 4 is the reinforcing bar material, and part that crab-bolt 4 inserted at road main part 1 mounting hole 11 uses the bar planting to glue and road main part 1 rigid coupling, and the part that crab-bolt 4 and flat steel belt ring 3 meet passes through welded fastening.
