Problems solved by technology
[0003] However, nowadays, when testing the freeze-thaw resistance of concrete test blocks, it is often necessary to manually record the number of freeze-thaw cycles of concrete. Due to the large number of freeze-thaw cycles, manual recording is more cumbersome, and it is easy to miss or record more, making the detection Errors occur in the process. In addition, the traditional freeze-thaw detection device cannot make the concrete test block well affected by the cold and hot air, which affects the effect of freezing and thawing the concrete test block.

The invention belongs to the field of freeze-thaw resistance detection, and particularly relates to an expressway pavement freeze-thaw resistance detection device and method. The expressway pavement freeze-thaw resistance detection device comprises a supporting seat, a freeze-thaw circulation box is fixedly connected to the supporting seat, and the two sides of the freeze-thaw circulation box are fixedly connected with a plurality of refrigeration pieces and electric heating pieces correspondingly, and a mother rod is rotationally connected into the freezing and thawing circulating box. According to the invention, the time relay is arranged to control the interval power-on and power-off of the refrigeration sheet, the electric heating sheet and the electromagnetic plate, so that the regulation and control mechanism can regulate and control the butt joint of the counting pen and the counting plate according to the freeze-thaw cycle process of the concrete test block, and marks on the counting plate, so as to automatically record the freeze-thaw cycle times, through the cooperation of the driving motor and the mother rod, the rotation of the concrete test block can be regulated and controlled, so that the concrete test block can better receive the effect of cold air or hot air.
Description
technical field [0001] The invention belongs to the field of detection of freeze-thaw resistance, in particular to a device and method for detection of freeze-thaw resistance of expressway pavement. Background technique [0002] Nowadays, in the process of constructing expressways, in order to ensure the quality of highway pavement, it is often necessary to conduct freeze-thaw resistance tests on the concrete on the road surface. Generally, multiple freeze-thaw cycle experiments are carried out on concrete test blocks until the weight loss of concrete If it is greater than 5%, the number of freeze-thaw cycles can be used to judge whether the quality of the concrete meets the required requirements. [0003] However, nowadays, when testing the freeze-thaw resistance of concrete test blocks, it is often necessary to manually record the number of freeze-thaw cycles of concrete. Due to the large number of freeze-thaw cycles, manual recording is more cumbersome, and it is easy to ...
