Description
Technical Field
The invention relates to the technical field of pavement materials, in particular to an asphalt pavement maintenance material based on a nano modified rare earth active ingredient.
Background
Asphalt pavements are widely used in high-grade highways, provincial and national roads and municipal roads in China. Asphalt pavement is exposed in atmospheric environment for a long time, asphalt serving as a cementing material is a high polymer material, and is easy to age under the combined action of traffic load, ultraviolet rays, water and the like for a long time, so that the asphalt pavement is prone to early diseases such as cracks, looseness, water damage, cracks, net cracks and the like, the service life of the pavement is further shortened, and bumping during driving and even safety accidents are easily caused. For a long time, the maintenance mode of 'damage before maintenance' is always adopted for asphalt pavement maintenance, so that the passive maintenance situation of 'no treatment for minor diseases and major repair for major diseases' is caused, and the heavy maintenance work is difficult to guarantee by limited maintenance cost. Aiming at the defects of the traditional maintenance mode, a road maintenance department starts to implement a preventive maintenance idea of the asphalt pavement to ensure the value of the asphalt pavement, and the main purposes of the maintenance method are to prolong the service life of the pavement, improve the pavement performance of the pavement, promote the safety level of the pavement and meet the user expectation. The reason why maintenance of asphalt pavement warranty requires sufficient maintenance cost to be applied to preventive maintenance of existing good roads is that when a road is in a healthy state, the cost for prolonging the service life of the road is far lower than the cost for repairing or rebuilding the road after the technical condition of the road is deteriorated, so that a maintenance strategy of 'good road first, more maintenance and less overhaul' is implemented. The maintenance of the asphalt pavement can prolong the service life of the pavement, for example, the service life of the pavement can be prolonged by three to five years for each preventive maintenance. Major repairs have a design life cycle, typically 15 or 20 years. Generally speaking, maintenance prolongs the service life of the asphalt pavement, and has high cost benefit, and the service life of the asphalt pavement is restarted in overhaul, which has great influence on road traffic and high cost.
The temperature in summer is higher, so that the asphalt pavement becomes very soft, the asphalt pavement deforms when a vehicle runs on the high-temperature asphalt pavement, and the service life of the asphalt pavement is sharply reduced after the vehicle rolls the asphalt pavement for a long time.
