Purpose and significance of regeneration of old asphalt pavement

　　2) Start the main oil pump into the circulatory system oil injection, while looking at the level indicator, in less than 2/3 of the height, stop oil injection, start the heat conduction oil circulation pump, so round trip, until the system is full of heat conduction oil.

Highway construction needs to consume a large number of asphalt, gravel, cement, sand and other road building materials, the road surface after a certain number of years will be maintenance and overhaul, alteration, the original used to pave the surface of a large amount of materials will be turned into waste, when these waste is dug out all into nature, will be abandoned, pollution and material waste and other environmental
Asphalt pavement Regeneration Technology, is the need to renovate or discard the old asphalt pavement, after digging and recycling, crushing, screening, and the new materials, the appropriate coordination, re-mixing, the formation of a certain road performance of recycled asphalt mixture, used in road construction surface, the bottom layer or pavement base of the whole process technology.
The regeneration and utilization of old asphalt pavement has the following significance:
(1) Through asphalt regeneration technology on the old pavement asphalt concrete recycling recycling, its circulation is applied to highway new road construction and maintenance, waste into treasure, to avoid waste pavement material stacking on the land occupation and environmental pollution;
(2) so that the old asphalt concrete in the incomplete aging of asphalt, gravel, sand and other applications, can reduce the construction of asphalt pavement and maintenance of new asphalt resources and gravel material resources consumption, reduce the destruction of gravel material mining to the natural environment;
(3) Reduce the cost of road maintenance and renovation, save the cost of the project, shorten the construction period, improve the progress of asphalt pavement.
Therefore, the recycling and utilization of old asphalt pavement has important economic and social environmental benefits.

After the overall solution is determined, then it is the details, from the processing process, assembly process, packaging transportation, economy, safety, reliability, practicality and so on to determine the location of each component, structure shape and connection mode.
However, in order to further ensure the future use of asphalt mixing station, but also to go through the improvement of the design phase, the original design as far as possible to improve.

In the work of asphalt mixing station, it will include many systems, each of which has different responsibilities.
The main function of the dust removal system is to be able to collect and collate the exhaust gas produced in the drying drum and the dust generated in other devices, and finally make its discharge substances conform to the relevant national standards and requirements.
Let's take a picture of the specific content below.

Any kind of mechanical equipment should go through the precision design, testing and other processes before making molding, asphalt mixing station is the same.
According to the survey found that for any Mobile Asphalt Mixing Plant mixing station, the following stages are required.

First of all, according to the needs of the market to determine the main technical parameters of the product to be designed, so the construction market survey, data analysis and other links are essential.
Secondly, through innovative conception, optimization of screening to determine the more ideal working principle, as well as the best solution to achieve this principle.
Finally, a schematic diagram of the overall design scheme should also be given.

　　(2) ignition so that the oil furnace normal operation, set the temperature 105℃-120℃, so that the heat conduction with dehydratio
/>Heating speed should not be too fast, generally not more than 20 ℃ per hour, when the temperature reached the set temperature after the shutdown, stay for a period of time (depending on the situation) to make the exhaust dehydration, so repeated several times can
/>Two times set the temperature 180℃-200℃, and then ignition, when the temperature rises to the set temperature, and then stay for a period of time, the purpose is to drain a small number of light components in the heat conduction

br />　　With the rapid development of China's basic construction, asphalt concrete mixing station and cement concrete mixing building have become necessary equipment in the construction and construction, and play an important role in the construction of the pro
br />Dust pollution of concrete mixing station has always been a difficult point of management, therefore, the traditional large concrete mixing station is mostly far away from the residential living quarters, built in convenient and remote l

br />　　7, regularly check whether the circulatory system has leakage, vibration and external sound, check whether the liquid surface of the expansion box exceeds the requirements, the sensitivity and reliability of the automatic control system of the asphalt mixer is met.
