Abstract

The invention relates to bituminous concrete construction temperature detection methods, in particular to a bituminous concrete construction temperature detection method of a bituminous pavement double-layer paving technology. The problem that an existing bituminous pavement double-layer paving technology can not conduct construction temperature detection and control in real time is solved. According to the bituminous concrete construction temperature detection method, an infrared thermometer is arranged at the rear end of an upper layer screed plate of a paver. A surface contact type thermometer is arranged on a lower layer screed plate of the paver, and the surface contact type thermometer is placed in front of a spiral material distributor. An inserting type digital display thermometer with a metal detection probe is mounted on a track. The paver is started, temperature collecting is conducted in the traveling process of the paver, the temperature data recorded by the inserting type digital display thermometer with the metal detection probe, the infrared thermometer and the surface contact type thermometer are transmitted to a data collecting system, the temperature data are detected in real time, and the construction temperature is controlled. The bituminous concrete construction temperature detection method of the bituminous pavement double-layer paving technology is used in the field of road and bridge engineering.

Description

technical field [0001] The invention relates to a detection method for asphalt concrete construction temperature, in particular to a detection method for asphalt concrete construction temperature of the asphalt pavement double-layer paving technology, and belongs to the field of road and bridge engineering. Background technique [0002] The construction temperature of asphalt mixture is the most important factor affecting the construction quality of asphalt pavement, and it is necessary to adjust the paving temperature of asphalt mixture during construction. The rolling temperature is strictly tested and controlled to ensure the construction quality of double-layer paving, and then meet the requirements of uniformity, compactness and flatness. The existing asphalt pavement double-layer paving technology cannot detect and control the construction temperature in real time. Contents of the invention [0003] In order to solve the problem that the existing asphalt pavement do...
