Description

Conductivity testing device for modified conductive asphalt pavement

Technical Field

The utility model belongs to the technical field of road and bridge construction machinery, concretely relates to modified conductive asphalt pavement's electric conductive property testing arrangement.

Background

The asphalt concrete pavement has the advantages of convenient construction, excellent anti-skid property, weak light reflection, good mute effect and the like, and gradually replaces the traditional cement pavement to become the preferred scheme of the highway in China. Over the years, with the vigorous development of highway industry in China, asphalt concrete pavements are laid in many mountainous areas and plateau areas, which greatly facilitates the traffic of local people, but the accumulated snow on the roads in winter also forms a great hidden trouble of safe driving, and particularly the accumulated snow on expressways has more and more obvious harm to the traffic.

In order to ensure the driving safety and the road smoothness and improve the operation efficiency of the road, effective measures must be taken to prevent and clear away the accumulated snow. At present, snow removal methods at home and abroad mainly comprise a manual removal method, a mechanical removal method and a snow-melting agent spreading method. Wherein the manual cleaning method has low efficiency and affects traffic; the mechanical cleaning method has higher requirements on equipment, and the snow removing equipment is in an idle state for most of time; the snow removing agent applied in the snow melting agent spreading method can cause the problems of environmental pollution, road surface damage and the like.

At present, papers such as experimental research on the conductivity of asphalt pavement materials, research on the conductivity mechanism and the electric heating performance of conductive asphalt mixtures and the like propose a new snow removal mode, namely: on the basis of common asphalt mixture, conductive phase material (such as graphite powder) is mixed according to a certain proportion to form conductive asphalt, so that the conductive asphalt is changed from insulating material into novel composite material capable of conducting electricity. The conductive asphalt is laid on the surface of the concrete road, and the conductive asphalt layer is electrified in a low-temperature environment, so that the temperature of the conductive asphalt layer can be increased, and the function of melting accumulated snow on the road surface is achieved. However, at present, no conductivity testing device for the modified conductive asphalt pavement exists, and constructors cannot detect the conductivity of the modified conductive asphalt pavement quickly and accurately; if the conductivity of the road surface is not good, the purpose of electric snow melting cannot be achieved.
