Monitoring device and method for pavement spreading temperature uniformity

Abstract

The invention discloses a monitoring device for pavement spreading temperature uniformity. The monitoring device comprises a control host, a plurality of temperature sensors and a display screen, wherein the temperature sensors and the display screen are electrically connected with the control host. The temperature sensors are mounted on the rear side of a spreader ironer according to the numbers and used for acquiring transverse distribution temperature data of the bituminous pavement. The control host is used for receiving and processing the temperature data acquired by all the temperature sensors. The display screen is used for receiving the temperature data transmitted by the control host and online displaying a monitored temperature, the temperature segregation degree and an early warning prompt. The invention further discloses a monitoring method for pavement spreading temperature uniformity. By adoption of the monitoring device and method, the current spreading temperature and temperature segregation degree can be rapidly inquired and timely fed back to an engineering manager, so that a construction process can be timely adjusted by the engineering manager, construction quality is ensured, and the monitoring device is simple and easy to operate and has good application prospects.

Description

technical field [0001] The invention relates to a monitoring device and a monitoring method for temperature uniformity of pavement paving, belonging to the technical field of pavement engineering. Background technique [0002] The "segregation" formed by uneven temperature in asphalt pavement construction is one of the important causes of pavement disease. In the construction of asphalt mixture, uniform density can only be produced if the entire pavement is compacted to the same degree, and the mixture in the low temperature area caused by temperature segregation will not be effectively compacted, resulting in low local surface compaction. If the porosity is too large, the pavement seeps and easily induces water damage, which affects the uniformity of the pavement quality. [0003] At present, there is a lack of means to monitor the segregation of the pavement during the construction process, and most of the post-event detection methods use manual sampling to measure the te...

Problems solved by technology

In the construction of asphalt mixture, uniform density can only be produced if the entire pavement is compacted to the same degree, and the mixture in the low temperature area caused by temperature segregation will not be effectively compacted, resulting in low local surface compaction. If the porosity is too large, the pavement seeps water and easily induces water damage, which affects the uniformity of pavement quality

[0003] At present, there is a lack of means to monitor the segregation of the pavement during the construction process, and most of the post-event detection methods use manual sampling to measure the temperature, which is limited in representation and cannot be fed back to the construction management personnel in time during the construction process to achieve timely segregation and rectification.
