Problems solved by technology

[0004] Most of the existing interlayer detection instruments are driven by motors, so the power supply needs to be increased during the on-site detection process, which greatly reduces the actual detection capability of the instruments. Interference causes large errors in the detection results

Abstract

The invention discloses a pavement interlayer bonding strength detector, comprising a base, a frame I and a frame II. A nut is movably arranged at the upper part of the frame I; a bevel gear I is arranged at the upper part of the nut; an axial limit device is arranged between the frame I and the frame II; one side on which the nut is arranged, on the frame II is connected with a rotating shaft in a rotating way; one end of the rotating shaft extends out of the frame II, a bevel gear II is arranged at one end of the rotating shaft in the frame II, and a handle is arranged at one end of the rotating shaft outside the frame II; a screw rod is arranged in the nut, a rotating limit device is arranged at the upper part of the screw rod, and a tension force sensor is connected at the lower end of the screw rod; a fixture is connected at the lower end of the tension force sensor and comprises a pressing plate and a cylinder connected on the bottom surface of the pressing plate; the inner diameter of the cylinder increases gradually from bottom to top, and a cylindrical lining is arranged in the cylinder; and the outer diameter of the cylindrical lining increases gradually from bottom to top, and the inner diameter of the cylindrical lining is equal from bottom to top. According to the pavement interlayer bonding strength detector, the running is stable, external interference is small, and detected data are accurate.

Description

technical field [0001] The invention relates to a tester, in particular to a tester for the bond strength between pavement layers. Background technique [0002] At present, with the increasing mileage of expressways in our country, the damage of asphalt pavement also shows an upward trend, causing huge economic losses. Insufficient bond strength between layers is one of the reasons for asphalt pavement's wrapping, shifting and water damage. The quality of the interlayer treatment of the pavement is related to the durability of the overall structure. The survey results show that a large part of the early pavement disease is due to Caused by poor bonding between the surface layers. Therefore, taking measures to strengthen the bond between the surface layer and the base layer in actual engineering is very important to the performance and service life of the pavement. [0003] In the road interlayer treatment technology, the construction technology has a great influence on the...
