Description
Technical Field
The utility model relates to a road engineering equipment technical field, concretely relates to pitch foaming device.
Background
The asphalt pavement can generate various types and different degrees of diseases after being used for a certain period of time, pavement materials are gradually aged under the combined action of traffic and the environment, the overall strength of the road is reduced, the damage phenomena are gradually increased, and the development of the pavement diseases can seriously influence the normal use of the road. The conventional road maintenance common scheme comprises direct paving and digging reconstruction. However, both of these repair processes have major drawbacks: directly laying a new structural layer on the original pavement without removing the diseases of the original pavement, only temporarily covering the diseases and lifting the pavement elevation to make the pavement structure more complicated and bring inconvenience to the maintenance and repair work in the subsequent operation; the maintenance mode of digging and rebuilding will produce a large amount of waste materials in the construction process, and the stacking and storage of the waste materials can also occupy a large amount of land resources, causing resource waste and environmental hazard.
the conventional maintenance and repair method not only causes a large amount of dug and milled asphalt mixture to be abandoned, but also causes the excessive exploitation of new stone and asphalt resources, thereby being a great resource waste, indirectly causing the reduction of forest vegetation, water and soil loss and seriously damaging the ecological environment. In addition, the reduction of carbon emission has become a global consensus, and various industries encourage the use of new technical materials to achieve the goals of energy conservation and emission reduction. In the field of highway construction, the application of traffic construction material recycling technology represented by recycling of asphalt pavement materials is mainly mentioned. Under the background, China needs to vigorously develop new green and low-carbon asphalt pavement maintenance and repair technologies, and the foamed asphalt cold regeneration technology is one of typical representatives of the green new technologies with vitality. The cold regeneration technology of the foamed asphalt can fully utilize the old materials, reduce energy consumption, greatly reduce carbon dioxide emission, improve the service performance of the pavement and shorten the construction period. As more and more asphalt pavements built in an early period enter a major and middle repair period, a large amount of waste asphalt mixture is generated. The foamed asphalt cold recycling technology has high requirements on the foaming effect of foamed asphalt, and the foaming effect of asphalt directly concerns the quality of the foamed asphalt cold recycling mixture.
The existing research shows that the good foaming effect (longer half-life period and larger expansion ratio) of the foamed asphalt can further improve the mixing uniformity of the foamed asphalt mixture and can improve the pavement performance and durability of the foamed asphalt cold-recycling mixture. Therefore, it is one of the ways to improve the foaming effect of asphalt to improve the foaming device of foamed asphalt.
