Based on the road age of the high-speed ring road test road in the automobile proving ground, this paper actively introduces the technology of sand mist sealing layer to carry out early preventive maintenance intervention on the high-speed ring road test road. In this paper, the construction technology, quality control and later effect tracking and comparison of sand mist sealing technology are described in detail. It was found that the sand mist seal material not only does not affect the use function of the road surface, but also has the effect of waterproof and anti-icing. It reflects the economical, effective, simple and easy application value of road surface protection of sand mist seal technology in the maintenance of high-speed ring roads in the test site. It has an instructive and practical positive effect on the management and implementation of the preventive maintenance of the test road of the future automobile test field.
