Abstract

The invention discloses a portable tester for testing the lay-down thickness and the temperature of asphalt mixtures. The tester can test the lay-down thickness and the temperature of the asphalt mixtures, and is especially suitable for testing the lay-down thickness and the temperature of an asphalt pavement constructed by means of a paver. The tester comprises a fixed ruler and a base. A vernier caliper is installed on the fixed ruler in a sleeved mode, and a probe is installed in a handle of the vernier caliper and provided with a temperature sensor and a digital thermometer. The tester has the advantages of being simple in structure, low in manufacturing cost because the tester is manufactured by stainless steel, durable in use, easy to measure, high in measuring precision and capable of measuring the thickness and the temperature simultaneously. Not only are work efficiency and measuring accuracy improved, but also consideration is given to protection for operation staff, the thermal insulation handle is adopted to avoid scalding, and the using effect is remarkable.

Description

technical field [0001] The invention relates to a measuring device for highway asphalt pavement construction, in particular to a portable asphalt mixture loose paving thickness and temperature measuring instrument, which can measure the loose paving thickness and temperature of asphalt mixture, and is especially suitable for measuring the loose paving thickness and temperature of asphalt pavement constructed by paver. Lay thickness and temperature. Background technique [0002] In the construction and maintenance process of asphalt pavement, the thickness of asphalt pavement is a very important technical index. During the paving process, the paving thickness of the pavement should be checked at any time to determine whether it meets the standard. In the actual operation now, the traditional direct sampling method is usually still adopted, that is, insert a steel drill or a screwdriver on the asphalt pavement and pull it out, and then measure the number with a ruler. To meas...
