Description

Ultra-thin top facing maintenance construction of pitch structure of mating formation Technical Field The utility model relates to the technical field of preventive maintenance engineering of highway pavement, in particular to an asphalt ultrathin overlay maintenance construction pavement structure. Background Expressways, which are referred to as expressways for short, refer to closed roads dedicated for high-speed running of motor vehicles. Expressways have different regulations in different national regions, different times and different scientific fields. In order to prolong the service life of the expressway, the preventive maintenance of the expressway pavement can delay the deterioration of the pavement condition through early intervention, and avoid the expansion of small problems into large problems, so that the overhaul time is delayed, the service life of the expressway is prolonged, the pavement can be kept smooth through timely maintenance, diseases are reduced, the driving safety and the comfort are improved, and the traffic safety accidents of the expressway can be effectively prevented and reduced through the preventive maintenance, and the use performance of the expressway is improved.
