At ordinary times, the common pavement is cement road and asphalt road. What are the differences between the two kinds of pavement maintained by the cold recycling machine?
1. Cement cold recycling
The cold recycling of cement makes full use of waste materials, and a certain amount of additives are added in proportion to continuously complete the milling, crushing, mixing, paving and compaction of materials at the natural ambient temperature, so as to build a new base with required performance and quality.
Compared with the traditional construction method, the cement cold regeneration has the advantages of low cost, high efficiency and good quality, which can reduce pollution.
2. Asphalt cold regeneration
Cold recycling of asphalt pavement: the recycled asphalt pavement materials obtained from milling and stripping of the old road are crushed, screened, extracted and measured for asphalt aggregate ratio, mineral aggregate gradation composition and performance indicators of the recycled asphalt. According to the mix proportion design of the new asphalt recycled mixture, some new aggregate, water, emulsified asphalt, etc. are properly added to mix the new asphalt pavement materials under normal temperature (without heating). The cold regeneration technology can reduce the cost by about 10-20%, and the production efficiency is very high.
