It is often seen that the construction workers at the roadside build roads for engineering construction. The roads are closed before they are built. During the road construction process, some advanced scientific and technological production processes will be used, mainly including concrete cold recycling and asphalt cold recycling. Today, the cold recycling machine rental manufacturers talk about the differences between the cement and asphalt construction processes.
1. Cold recycling of cement
The cold recycling of concrete shall flexibly use the waste raw materials, and add a certain amount of additives according to the proportion to continuously complete the milling, crushing, mixing, pavement construction and compaction of the raw materials at the natural ambient temperature, so as to build a new base with the required characteristics and quality.
Compared with traditional construction methods, concrete cold recycling has low cost, high efficiency and high cost performance, which can reduce environmental pollution.
2. Leaching cold regeneration
Cold regeneration of asphalt road: the recycled asphalt road raw materials obtained from the milling and separation of the old road are crushed and screened, extracted and measured the asphalt stone ratio, mineral aggregate gradation composition and the performance parameters of the recycled asphalt, and then designed according to the new asphalt reconstruction mixture mix proportion. A part of new bone material, water, emulsified asphalt, etc. are added appropriately, and the new asphalt road raw materials are mixed under normal temperature (without heating). The cold regeneration technology can reduce the cost by 10-20% and has high productivity.
The technology of asphalt refrigeration regeneration has promoted the development and utilization of industrial production wastes and the comprehensive utilization of renewable energy, as well as the application of new technologies such as raw material recycling and energy replacement, and the development, design and scientific research of new technologies and processes. The application of cold recycling technology of asphalt roads has more obvious environmental benefits for maintaining green ecology and green sustainable development trend, and plays a key role in improving road ecological and environmental protection.
