In-situ cold recycling of roads belongs to the category of road maintenance and reconstruction. It mainly solves the problem of base layer damage on asphalt pavement. Specifically, road cold recycling refers to making full use of the existing asphalt road old paving materials (surface layer and base layer), adding some new aggregates when necessary, and adding a certain amount of additives (cement, foamed asphalt, emulsified asphalt, lime) in proportion. , fly ash, etc.) to continuously complete the milling, crushing, mixing, paving and compaction of materials on-site at natural ambient temperatures, thereby building a new base with required performance and quality
Design and construction specifications and acceptance assessment standards
In view of the significant economic and social environmental benefits of asphalt pavement regeneration, it should be widely used. At the same time, with the increase of high-grade asphalt pavements in our country, we will surely face more regeneration of old pavements in the future. Utilization issues. Therefore, how can we comprehensively and systematically organize and process this technology on the basis of existing research results, and conduct necessary experimental verifications so that this technology can reach specifications and standardization to guide national road maintenance? Engineering construction projects are an important task before us.
Standardization and serialization of regenerants
Foreign regenerants are all researched and provided by the chemical industry department, but our country's petroleum department has not yet been able to take them into consideration. In the past, most of the asphalt pavement structures of my country's highways were thin and generally did not need to be reused, so the overall demand for regeneration agents was not large. However, with the development of highway construction in my country, asphalt pavement recycling will be a daily application technology on highways in the future, and the demand for regenerants will definitely increase greatly. To this end, the sources and varieties of regenerants must be expanded and their specifications Transformation and serialization will be a common research topic for the petrochemical sector and the highway sector.
Testing of the regeneration effect of old asphalt
When the old material is in a hot state, the old asphalt is in a molten state and can be blended with the liquid new asphalt. However, this is only a theoretical speculation, and the actual situation of separation and mixing cannot be known. Although the physical and mechanical properties test of the regenerated mixture can indirectly analyze the quality of the regeneration effect, it is still not an intuitive detection method. For this reason, convenient and rapid detection methods must be developed.
Recycling Machinery
Paving recycled asphalt pavement requires many steps and is complex. It requires more labor and is quite troublesome, so that some people are discouraged. Therefore, how to improve the level of construction mechanization and reduce manual labor is the key to whether asphalt pavement recycling technology can be promoted on a large scale. To pave large areas of recycled asphalt pavement, there is an urgent need for road excavation machinery, old material crushing and screening machinery, and mixture mixing machinery. It is necessary to have both large machinery suitable for centralized plant mixing and various small machines suitable for use in the road maintenance department. It is urgent to actively organize forces, formulate plans, and effectively develop and produce various recycling machinery.
Using asphalt regeneration technology, old materials can be fully utilized. By selecting appropriate proportions and blending ratios of new and old materials, a recycled mixture of quite good quality can be regenerated. Preliminary research and practice have shown that this recycled mixture can be used as asphalt surface layer on high-grade highways. At the same time, the use of asphalt recycling technology can achieve considerable economic and social benefits.
Research on the characteristics of asphalt additives and the road performance of mixtures
People have conducted a lot of research on the many diseases that occur in asphalt pavement during use, and pointed out that adding asphalt additives can significantly improve the performance of asphalt pavement. Performance In addition to commonly used resin, rubber and copolymer asphalt modifiers, some new additives have appeared internationally in recent years.
The on-site cold regeneration machine is a high-efficiency, multi-purpose construction machine. It is mainly used for milling of asphalt concrete pavement and regeneration of old asphalt pavement after adding asphalt, water and other materials. It can also be used for on-site mixing operations of the base and bottom stabilized soil of highways, urban and rural roads, airports, docks, parking lots and other projects.
The water-stabilized base layer can be regenerated in all directions
