Asphalt pavement loose paving thickness tester

Abstract

The invention discloses an asphalt pavement loose paving thickness tester, which mainly relates to the technical field of road construction equipment, and comprises a base, a lead screw, a speed reducer, a driving motor, a limiting column, a graduated scale arranged on the limiting column, a nut arranged on the lead screw and matched with the lead screw, a pointer arranged at one point of the nutand pointing to the graduated scale, and a probe connected to the other end of the nut, the lower portion of the probe is an arc-shaped protrusion, a through hole penetrating through the center of theprobe is formed in the arc-shaped protrusion, a limiting plate corresponding to the arc-shaped protrusion is arranged at the end, close to the arc-shaped protrusion, of the through hole, a fixing plate is arranged at the end, close to the center of the probe, of the through hole, and a ball column is arranged between the limiting plate and the fixing plate and connected with the fixing plate. Sensors are arranged at the column end of the ball column and the center of the probe, the displacement of the nut can be accurately observed through the graduated scale and the pointer, the distance from the bottom of the probe to the axis of the ball column is subtracted from the overall displacement, the loose laying thickness is obtained, measurement data are accurate, efficiency is high, and influences of external factors are not likely to happen.

Description

technical field [0001] The invention mainly relates to the technical field of road construction equipment, in particular to an asphalt pavement loose pavement thickness measuring instrument. Background technique [0002] In the past few decades, my country's expressways have undergone a period of rapid development, and the requirements for construction quality have also increased during the rapid development of expressways. Among them, the quality of pavement construction affects the quality of the entire road construction project. Parameters such as the thickness of the loose pavement have a very important impact on the performance and life of the formed pavement and the use of materials. The thickness of the loose pavement refers to the asphalt pavement before compaction. , the thickness of the asphalt mixture paved by the paver. More and more highways use asphalt mixture to build the road surface. It is a necessary procedure to detect the loose paving thickness of the asp...
