Abstract

The invention discloses a device and method for real-time continuous measurement of thickness of an uncompacted layer spread by an asphalt spreader. The device comprises a hollow horizontal reference surface measuring tube, a horizontal reference surface height range finder, a hollow spread-thickness measuring tube, a spread-thickness range finder and a horizontal reference surface measurement liquid container. According to the invention, the problem that real-time measurement cannot be performed in the asphalt spreading process is solved, a dynamic actual thickness of the uncompacted layer during spreading of a whole road is provided, labor intensity and error rate are reduced, and in the process of real-time measurement, the horizontal reference surface height tube (i.e. the horizontal reference surface measuring tube) directly reflects the non-spread pavement condition, so that influences from terrain and other measurement conditions are avoided.

Description

technical field [0001] The invention relates to a device and method for measuring the virtual paving thickness of an asphalt paver. Background technique [0002] In the process of asphalt pavement construction, the virtual pavement thickness of asphalt paving is an important indicator of quality control. At present, the measurement of virtual paving thickness mainly depends on the way of pulling the reference line and the height sensor of the ironing plate of the paver. [0003] The way to pull the datum line is to draw a height datum line on the surface of the paved underlayment according to the design elevation of the paving layer. When paving, pave according to the height of the datum line. The laying of the datum line must be very careful. Its length is preferably 150-200m, and it is difficult to guarantee the tension if it is too long. Steel wire rope should be used for the pull wire, and the tension force should not be less than 1000N. There should be an overlapping s...
