China is now in a period of rapid development, and the national road network has also increased rapidly. In order to develop the roads, we must take measures to maintain them so that we can maintain good road performance for a long period of time, and we can also see the investment returns from huge investment in road construction.
Therefore, since conservation must be supported by a strong conservation maintenance support system, preventive conservation has played an indispensable role. In many rural areas, many people think that maintenance is the same concept as maintenance. It has long been accustomed to wait until the road begins to appear damaged before it is remembered to be repaired, and it is not considered when the road is still in good condition. Preventative maintenance. Therefore, many people often lack awareness of this aspect of conservation.
Today Xiao Bian also wanted to talk about the new concept—Pavement Preventive Maintenance, which means that the road maintenance department is good at protecting the highway pavement structure or the initial stage of road surface damage. It is just like when we were young. To reduce the road surface disease in advance to further deeper development, so as to achieve the purpose of prolonging the service life of the road, maintaining the road intact rate and flatness, improving the quality of the highway, reducing the life cost of the highway, and extending the mode of operation or overhaul deadline purpose and practical methods. The traditional maintenance is to wait until after the destruction of the road to consider maintenance. At this time, the road has undergone structural damage and needs to be dealt with by the grassroots. Therefore, it takes a long time to maintain and occupies the road to cause traffic jams, and requires a lot of investment. This is not the case. Saving costs is equivalent to entering the maintenance phase directly. And before a road is to be repaired, its original traffic flow cannot be fully utilized, causing congestion.
Therefore, scientific and rational use of pavement preventive maintenance in road maintenance, not only can extend the life of the road, while reducing working hours of road maintenance, saving maintenance costs. This is a kind of advanced method. The key point for pavement preventive maintenance is to properly advance maintenance according to the conditions of road operations, combine cyclical conservation with preventive conservation, and enhance road defense capabilities. The road administration departments should increase daily inspection efforts and conduct special remediation projects such as afforestation and beautification, pre-bridge inspection, pavement repair, bridge maintenance, roadbed standardization construction, and summer crack repair in accordance with the external factors of different regions and different climates, so as to make road surface diseases. To be effectively controlled.
