Abstract

The invention discloses a system for detecting the paving temperature segregation of an asphalt pavement. The system comprises a temperature sensor group which is arranged on paving equipment and is 10-15cm from the pavement, a distance collection device used for collecting a paving distance and a paving speed, a processing device which is used for receiving temperature information of the pavement collected by the temperature sensor group, receiving paving distance information and paving speed information collected by the distance collection device and performing analysis processing, a display device which is used for displaying analysis processing results for the temperature information, the paving distance information and the paving speed information from the processing device, and a storage device which is used for soring the temperature information, the paving distance information and the paving speed information. The invention further discloses a method for detecting the paving temperature segregation of an asphalt pavement. By adopting the system and the method for detecting the paving temperature segregation of an asphalt pavement, the temperature segregation detection results are accurate.

Description

technical field [0001] The application relates to the technical field of engineering construction, in particular to a detection system for temperature segregation of asphalt pavement paving, and also to a detection method for temperature segregation of asphalt pavement paving. Background technique [0002] Asphalt pavement paving temperature segregation refers to the uneven temperature distribution of the pavement after paving due to the inconsistent temperature drop rate of the mixture in different parts during the transportation and paving process of hot mix asphalt mixture. [0003] Hot mix asphalt mixture is very sensitive to temperature, temperature segregation occurs on asphalt pavement after paving, under the same rolling process, the area with lower temperature is difficult to compact, the degree of compaction is relatively low, and the void ratio of the pavement is relatively large. Potholes and looseness are easy to appear; the road surface in areas with high tempe...
