Effect evaluation experiment method for repairing steel bridge pavement pit slot by asphalt brick induction heating

Abstract

The invention discloses an effect evaluation experiment method for repairing a steel bridge pavement pit slot by asphalt brick induction heating. The method comprises the following steps: manufacturing and cutting a track plate; coating asphalt on the cutting surface of the cut track plate and spreading an induction material; repairing the rut plate through induction heating; processing the repaired rut plate into three small beam test pieces and three oblique shear test pieces, and carrying out three-point bending and oblique shear experiments; manufacturing a Marshall test piece and bondingthe Marshall test piece with the steel plate through induction heating to form a composite test piece; and carrying out interlayer shearing and drawing experiments on the composite test piece. The method can solve the problems that a quantitative evaluation method is lacked at present, the reliability of repairing effect feedback is greatly reduced, and maintenance work is difficult to scientifically guide.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement pothole repair, in particular to an experimental method for evaluating the effect of asphalt brick induction heating to repair a steel bridge pavement pothole. Background technique [0002] In the 21st century, our country is now an era of rapid development of bridge construction, and has entered the peak period of bridge construction. As an auxiliary facility of a long-span steel bridge, the steel bridge deck pavement is a load-bearing structure laid directly on the steel bridge deck, which protects the steel plate and bears load together with the steel bridge deck structure, and has a road surface that meets the driving requirements of vehicles. It is also the first line of defense against corrosion damage of the steel bridge structure and improving the durability of the steel bridge structure. Therefore, it is very easy to produce serious pits and other diseases. [0003] As one of t...
