Guide: changing the traditional road maintenance mode and promoting the application of Yingda thermal regeneration technology, which can realize 100% in-situ recycling of the original pavement, on urban roads in Jiangsu Province, has become the consensus of Jiangsu provincial construction system. On January 12, the Jiangsu Provincial Department of housing and urban rural development hosted the Jiangsu Provincial Urban Road on

it has become the consensus of the construction system in Jiangsu Province to change the traditional road maintenance mode and promote the application of Yingda thermal regeneration technology, which can realize 100% in-situ recycling of the original pavement, on urban roads in Jiangsu Province

on January 12, the Department of housing and urban rural development of Jiangsu Province hosted the "Symposium on the application of geothermal regeneration technology in urban roads of Jiangsu Province" in Nanjing to jointly discuss how to further promote the application of economical and environmental friendly Yingda geothermal regeneration technology in urban roads of Jiangsu Province, Wang Xiang, deputy director of the Department of housing and urban rural development of Jiangsu Province, Zhang Jian, director of the urban construction office Wang Yi, deputy director of Nanjing Municipal Public Utilities Bureau, and more than 80 leaders from the Construction Bureau (Committee) and Municipal Public Utilities Bureau of 13 cities under the jurisdiction of the province and heads of municipal facilities management and maintenance units attended the meeting. The guests watched the demonstration of geothermal regeneration on Asphalt Pavement by Inda at zero ℃, and then discussed how to increase the application of geothermal regeneration technology in urban roads in Jiangsu Province

the problem of traditional maintenance was solved easily, "Nanjing experience" was widely recognized

on the 12th, the minimum temperature in Nanjing reached -6 ℃, but Yingda "road repair king" successfully completed the repair process of a large area of 18 ㎡ of road disease, and then Yingda large geothermal regeneration unit showed you the innovation of the whole Lane Road, which perfectly overcame the shortcomings of traditional maintenance methods that cannot be constructed in winter

as the first city in Jiangsu Province to introduce Yingda geothermal regeneration technology, Du Jun, director of the municipal business department of Nanjing Municipal Public Utilities Bureau, introduced in detail the changes brought by Yingda geothermal regeneration technology to the appearance of urban roads in Nanjing to the guests at the meeting. Since the large-scale introduction of Yingda geothermal regeneration technology in 2008, the problems of delayed road maintenance, construction disturbing residents, and difficult maintenance in winter in Nanjing have been solved

Du Jun said that since 2008, Yingda geothermal regeneration technology has been selected for the overall new projects of 12 roads in Nanjing, saving 50300 tons of asphalt mixture and 21200 square meters of waste residue emission, with obvious energy-saving effect; Yingda thermal regeneration adopts the interlayer thermal bonding technology, and the bonding force between layers is about three times that of the traditional process, and the disease resistance is much better than the traditional process. The excellent stability of the regenerated asphalt material has an excellent treatment effect on the rutting treatment of the intersection; Compared with the traditional process, Yingda geothermal regeneration technology has better repair efficiency and less traffic interference. Today, when the traditional maintenance method is difficult to meet the modern maintenance needs of urban roads, Yingda has improved the road maintenance level of the whole urban area of Nanjing with geothermal regeneration technology, ensuring the timely flow of urban roads. This view was highly recognized by the guests present

if the oil hole of the buffer in Nanjing is blocked, Wang Yi, deputy director of Nanjing Municipal Public Utilities Bureau: the promotion of new technology needs to strengthen policy guidance

"everyone is positive about geothermal regeneration technology, but if it is to be popularized and applied on a large scale, there will be a lot of resistance". Wang Yi, deputy director of Nanjing Municipal Public Utilities Bureau, pointed out that the promotion process of new technology is a challenge to traditional maintenance technology, traditional habits and the original industrial structure, Inevitably, traditional road maintenance enterprises or related industrial chains and interest chains trying to improve the work level will be damaged. Therefore, policies must be adopted to "support, guarantee and guide"

Wang Yi shared with the guests the experience of Nanjing in promoting Yingda's geothermal regeneration technology in recent years: since Nanjing purchased 10 "road builders" at one time in March last year, the Nanjing municipal government has always adhered to policy guidance, actively promoted the application of geothermal regeneration technology, and issued some hard and fast regulations. First of all, the cost of purchasing the "king of road repair" is paid by the government, which greatly reduces the financial pressure of the subordinate maintenance departments. In use, the "king of road repair" has the characteristics of low material consumption, high efficiency, good quality and so on, which further reduces the comprehensive cost of road maintenance. Our hydraulic universal material testing machine manufacturer technology compiles a copy of the operating procedures, installation and commissioning of the hydraulic universal material testing machine for everyone; After the "road repair king" was put into use, Nanjing Municipal Public Utilities Bureau also put forward higher requirements for the maintenance department, "we have provided the" road repair king "this kind of fast and efficient equipment, which has created conditions for rapid maintenance. Therefore, it must be handled within 2-3 hours after receiving the road disease complaint"; At the same time, the application and promotion of geothermal regeneration technology for Yingda in Nanjing is in the charge of a specially assigned person, and relevant specifications have been formulated according to practice. Through the "king of road construction" maintenance competition and other activities, efforts have been made to improve the enthusiasm and operation level of each maintenance unit in using new technology

do a good job in the promotion and application plan and clarify the implementation process

Deputy Director General Wang Xiang pointed out in the summary speech of the meeting that the construction of infrastructure in Jiangsu has been in the forefront of the country in recent years. With the acceleration of urban road construction, the maintenance demand is also increasing, and the masses and competent departments also put forward higher requirements for maintenance. In this case, the current situation that the traditional maintenance technology is not timely, environmentally friendly and has a great impact on traffic must be changed. Compared with the traditional technology, Yingda geothermal regeneration technology has the characteristics of saving environmental protection, high quality of road repair, high degree of mechanization and small traffic interference. The practice in various parts of the country has proved that this technology has been very mature and is worth vigorously promoting. The future focus of Jiangsu Province is how to deal with the conflict between new technology and traditional maintenance industry in the technological transformation. "

Wang Xiang pointed out that the promotion of geothermal regeneration technology is a major event related to the implementation of the scientific concept of development and the promotion of the construction of an energy-saving society. It is the need for the long-term development of the industry. We must fully understand the importance and necessity of new maintenance technology in road application and promotion; We should formulate plans and plans for popularization and application. In the process of popularization, we can gradually master technology, accumulate experience and improve ability according to the method of pilot before popularization. In terms of conflict with the original industrial chain, we should adopt a multi-channel and multi-mode customer model to reduce resistance. Through technology introduction, equipment introduction, technology cooperation, which is also a great recognition of our work, we should transform the existing enterprises, make good use of the existing maintenance technology team, and expand the scale of promotion and application as soon as possible

at present, Jiangsu Provincial Department of housing and urban rural development has taken Yingda local technology as the key promotion technology in the construction industry, and will actively guide and support the provincial municipal departments to increase the application in the future. Wang Xiang hopes that through the promotion of this technology, a win-win situation of enterprise effect and social effect will be created, so that the level of maintenance technology in Jiangsu will reach a new level
