Paver asphalt temperature segregation infrared detection system and detection method

Abstract

The invention provides a paver asphalt temperature segregation infrared detection system and a detection method, and the system comprises an electric subsystem and a data analysis subsystem; the electric subsystem is used for detecting asphalt temperature segregation during pavement construction and storing detection data; the data analysis subsystem is used for consulting the data detected by the electric subsystem and analyzing the paving quality of the asphalt pavement so as to obtain a complete detection result of the entire paved road. With the invention, real-time monitoring of the interior of the asphalt pavement can be performed during pavement paving; adverse factors generated during asphalt paving can be obtained with the monitoring results, and a solution scheme can be formed at first time; therefore the adverse factors can be controlled, and their effects can be reduced or completely eliminated, which ensures the paving quality.

Description

technical field [0001] The invention relates to road engineering machinery, in particular to an infrared detection system and detection method for asphalt temperature segregation of paver. Background technique [0002] When paving asphalt in road construction projects, the degree of compaction (Degree of Compaction) of the road surface will be uneven due to the temperature segregation of the asphalt material. Large, these areas are prone to early damage when the asphalt road is put into use, for example: there will be looseness, mesh cracks, potholes, local severe ruts, local oil flooding, and uneven depth of the newly paved asphalt pavement structure. All will inevitably lead to a greatly shortened service life of the asphalt pavement, seriously affecting the economic and social benefits of the road. [0003] The traditional asphalt pavement paving temperature detection is only a random detection of a single measurement point, which has great chance and randomness, so it c...

[0002] When paving asphalt in road construction projects, the degree of compaction (Degree of Compaction) of the road surface will be uneven due to the temperature segregation of the asphalt material. Large, these areas are prone to early damage when the asphalt road is put into use, for example: there will be looseness, mesh cracks, potholes, local severe ruts, local oil flooding, and uneven depth of the newly paved asphalt pavement structure. It will inevitably lead to a greatly shortened service life of the asphalt pavement, seriously affecting the economic and social benefits of the road

[0003] The traditional temperature detection of asphalt pavement only randomly detects a single measurement point, which has great chance and randomness, so it cannot fully and truly reflect the quality of asphalt pavement paving

If artificial equipment, such as infrared cameras and other equipment, are used to monitor the road surface, and then analyze the data, and then obtain the data information of the paved road surface, the pavement may have been paved or even compacted at this time. The obtained data loses practical significance

Since the pavement that has been paved cannot be completely shoveled and re-paved, it will inevitably cause delays in the construction period and a large amount of waste of materials. This is a result that no construction party or supervisor is willing to encounter.
