Problems solved by technology

In the airport concrete pavement project, a minimum index is proposed for the texture depth of the pavement: the average texture depth of the new pavement is not less than 1.0mm, and the surface of the cement concrete pavement of the grooved runway is roughened before the groove is grooved. The average texture depth after rough

Abstract

The invention relates to a device and method for measuring the thickness of cement mortar at the surface layer of pavement concrete. The device comprises an outer-ring cylinder and an inner-ring cylinder, the external diameter of the inner-ring cylinder is lower than the internal diameter of the outer-ring cylinder, both the upper and lower ends of the outer-ring cylinder are open, the inner-ring cylinder is provided with a bottom, the upper end of the inner-ring cylinder is open, the inner-ring cylinder is nested in the outer-ring cylinder, the upper end of the outer wall of the outer-ring cylinder is provided with graduation lines of the outer-ring cylinder, and the upper end of the outer wall of the inner-ring cylinder is provided with graduation lines of the inner-ring cylinder. According to the invention, the thickness of the cement mortar at the surface layer of the concrete can be rapidly and effectively measured.

Description

technical field [0001] The invention relates to the technical field of concrete thickness measurement, in particular to a device and method for measuring the thickness of cement slurry on the surface of pavement concrete. Background technique [0002] At present, traffic accidents often occur on highways and airports in various countries in the world. One of the main reasons is that the insufficient friction coefficient of highway pavement and airport pavement leads to brake failure of automobiles and aircraft. In recent years, with the continuous increase of civilian models, the performance requirements of aircraft for the flight area pavement are also continuously improved. Not only is the pavement required to have sufficient strength to resist the impact load of the aircraft, but also its surface structure is required to be able to withstand the impact of the aircraft. When landing and taxiing, sufficient frictional resistance is generated to ensure the safe take-off and ...
