This invention specifically discloses a test device for testing the reflective performance of traffic road markings. The device includes a test chamber, with an asphalt road sample placed at the bottom. Reflective road markings are applied to the road surface, and a drainage device is provided on the side of the asphalt road. An environmental simulation device and a road marking light-sensing test device are respectively installed above the road markings to be tested. The environmental simulation device consists of a heating device, a cooling device, a raindrop device, and a friction device, simulating the effects of different environmental and vehicle factors on traffic markings. The road marking light-sensing test device consists of a sliding block, a rotating shaft, an illumination lamp, and a retroreflection coefficient measuring instrument. This invention can simulate complex environments such as wet-dry cycles, wheel friction, and alternating hot and cold temperatures on the road markings on the asphalt sample. Finally, the data received by the retroreflection coefficient measuring instrument is used to analyze the reflective performance of the road markings, thus more realistically reflecting the reflective performance of traffic road markings.

This invention discloses a device and method for evaluating the self-healing performance of CCUS well cementing. In this device, a liquid injection unit and a gas injection unit are respectively connected to the cavity of a reaction vessel. A data acquisition unit is connected to the reaction vessel and collects relevant parameters within the reaction vessel's cavity. The data acquisition unit is connected to a data processing unit. A control unit is connected to both the data processing unit and the data acquisition unit. Self-healing cement samples and ordinary cement samples undergo pre-damage treatment. Then, breakthrough pressure tests are performed on the self-healing pre-damaged samples and the ordinary pre-damaged samples, respectively, to obtain the breakthrough pressure of the self-healing sample and the breakthrough pressure of the ordinary sample. If the breakthrough pressure of the self-healing sample is greater than that of the ordinary sample, the self-healing cement sample is judged to have the ability to self-heal microcracks. This invention is reliable in principle, convenient to operate, has a reasonable structure, and the testing process is simple and quick.
