Abstract

The invention discloses a non-contact high-precision continuous detection device for the construction temperature of an asphalt pavement, relates to a detection device for the construction of the asphalt pavement, and aims to solve the problem that an existing detection device for the construction temperature of an asphalt pavement cannot accurately reflect the real temperature condition in an asphalt mixture. The device comprises a network controller, a support, a temperature measuring assembly and an external field factor testing assembly, wherein the temperature measuring assembly is connected with the support, and the external field factor testing assembly and the temperature measuring assembly are both connected with a data receiving end of the network controller through data lines. The invention relates to the technical field of pavement construction detection. The surface temperature of the asphalt pavement can be continuously detected in real time through the temperature measuring part; the external field factor testing part can synchronously test external field factors along with the temperature measuring part, and the internal temperature of the asphalt pavement can be accurately predicted through an asphalt pavement internal high-precision temperature prediction model of a support vector machine based on acquired external field factor data.

Description

technical field [0001] The invention relates to an asphalt pavement construction detection device, in particular to a non-contact high-precision continuous detection device for asphalt pavement construction temperature. The invention relates to the technical field of pavement construction detection. Background technique [0002] During the construction of asphalt pavement, the construction temperature should be tested, because the temperature has an important influence on the compaction quality of asphalt mixture. If the temperature in the rolled area of ​​the asphalt mixture layer is too high, there will be problems such as "rolling" in front of the roller of the roller, asphalt mixture on both sides of the roller, sticking of the mixture to the wheel, and cracks in the rolled layer; Accelerate the aging of asphalt and affect the performance of asphalt mixture. When the temperature is too low, the viscosity of the asphalt increases, making it difficult to compact the aspha...
