Abstract
The existence of diversified entities makes the allocation of resources required for highway maintenance more complex.In some regions,there is a higher allocation of road maintenance resources,while in others,sufficient road maintenance resources are not available.In addition to spatial imbalance,the allocation of highway maintenance resources is also uneven in the temporal dimension.During a certain period of time,some areas of highways may receive maintenance resources,while during other periods,maintenance resources may not be available in a timely manner.The existence of this reality makes preventive maintenance measures extremely important.At the same time,preventive maintenance can prevent the spread of diseases and increase the service life of road surfaces by preventing them in advance when they are minor or have not yet formed.In this article,various road surface diseases were classified and analyzed for their characteristics.Subsequently,disease statistics were conducted on three sections of the experimental road surface,including the coverage area and proportion of various diseases in the total area.Specific measures for early preventive maintenance,mid-term preventive maintenance,and later preventive maintenance were proposed.关键词
