Description

Technical Field

[0001] The utility model belongs to the field of temperature and humidity sensor integration, and in particular relates to a monitoring integrated device for a road pavement layer. Background Art

[0002] The asphalt pavement of cement concrete bridge is a protective structure layer that is paved and compacted on the bridge deck after mixing mineral materials and asphalt binder. The pavement layer is generally divided into two layers, the upper layer is also generally called the wear layer or anti-skid layer, which is used to resist the wear and shear force caused by vehicle loads on the bridge pavement, and provides the roughness required by the wheels with a thickness of 4 to 6 cm. The main function of the lower layer is to correct the unevenness of the bridge deck structure and ensure the paving thickness of the upper layer. Sometimes it also has a waterproofing effect. Generally, dense asphalt concrete is used with a thickness of 3 to 5 cm. The upper and lower layers of the pavement layer should form a whole to form a stable, durable, flat and anti-skid pavement structure.

[0003] In order to better test the road performance of the bridge deck pavement and study the defects of the asphalt pavement of cement concrete bridges, it is necessary to study the interlayer state of the pavement and detect the temperature and humidity values ​​between the layers. During the installation of the temperature and humidity sensors of the asphalt pavement of the bridge deck, it is necessary to integrate and protect the temperature and humidity sensors to improve the survival rate of the temperature and humidity sensors, so as to better study the relevant states in the asphalt pavement.

[0004] Since there is no related integrated device for temperature and humidity sensors, the temperature and humidity sensor integration of the asphalt pavement layer of the cement concrete bridge deck can only be completed by covering and protecting it with the asphalt mixture on site. The temperature of the asphalt mixture is high and asphalt is a waterproof material, which leads to problems such as complicated process of burying temperature and humidity sensors on site, difficult line protection, low sensor survival rate, inaccurate temperature and humidity value measurement, etc. Utility Model Content
