"Longevity Asphalt" Makes the Road "Smart"
China Jiangsu Netcom Recently, the Jiangsu Provincial Communications Research Institute Co., Ltd. (Su Jiaoke) is about to land the A shares. The news has aroused the attention of the domestic engineering consulting industry, and has also aroused the interest of the general public. Then this research-type high The technical advantages and innovations that technology companies rely on can stand out in the highly competitive engineering consulting industry. With these questions, the reporter conducted an “unannounced visit†to Su Jiaoke. The reporter learned that in fact, the work of the SJCS is closely related to the lives of ordinary people. As a private high-tech enterprise covering highways, water transportation, municipal administration, railways, urban rails and other large transportation areas, with a contract value of more than 1 billion yuan each year, Su Jiaoke has developed a large number of key technologies, hot spots, and difficulties that are closely related to the development of the transportation industry. The basic and applied research and development work has formed its own superiority research area in the national transportation industry, and has obtained a number of nationally-leading and even world-leading scientific research achievements in the fields of bridge technology and asphalt pavement research. To learn more, yesterday's reporter walked into Sujiao Keji and learned about the core technology it possessed and interviewed Su Jiaoke and his secretary Pan Lingsong.
"Longevity Asphalt" makes the road enjoy life for more than 10 years. Su Jiaoke Dong Jishu Pan Lingsong told reporters that Asphalt Pavement technology is a technique proud of Su Jiaoke. "Using this new type of asphalt, at least 'longevity' than conventional asphalt." Times, the service life of the road can reach 20 years or so. According to the experts of the Soviet Bureau of Communications, the vast majority of expressways that have been built in China are semi-rigid asphalt pavements, and the cement and stone are used in the base, although the overall strength is high. The body is good, but because of the defects of the cement material, it is easy to appear cracks, pits, and other damages due to the high temperature or rainy and humid seasons. This is coupled with the overloading of automobiles, poor management, and poor maintenance. Asphalt roads usually have to be completely overhauled in 7 to 8 years. After 8 years of efforts to develop this new technology, Su Jiaoke Branch has transformed the traditional asphalt road into a flexible grass-roots road that can adapt to the domestic climate conditions and road environment, and can enhance the road surface structure and resist deformation. At present, this new type of asphalt has been laid in the Wuxi section of Shanghai-Nanjing Expressway for more than 20 kilometers. The secretary-general said, “After the conditions are ripe for the future, it will be promoted in a wider area.†“The road can not only increase longevity but also have high IQ.†Pan Lingsong told reporters that the Internet of Things technology has become more and more mature and they are experimenting. Pressure sensors and ASG strain sensors are installed in the flexible asphalt to provide roads with “high IQ†through sensing equipment. “These sensors are connected to the road surface equipment and can reflect the condition of the road surface in time. If the road surface is damaged, the data center can be quickly and accurately. If there is any unexpected situation on the road, such as a fog in front, a car accident, etc., the smart road will firstly inform the driver through the electronic screen on the road and guide the vehicle to avoid it.†The Division completed research on more than 50 scientific research projects in the field of asphalt pavement technology, and formed a number of core technologies represented by rubber asphalt technology, Superpave asphalt technology, SMA technology, road reconstruction and expansion technology, which are based on asphalt pavement regeneration technology and environmental protection concepts. , and built a new road project and highway reconstruction project based on core technology Up to 17 road system solutions in 3 areas of municipal engineering provide technical services and consultations for up to 10,000 kilometers of high-grade highways in 17 provinces across the country, solving a large number of practical engineering problems for the owners and promoting our country’s The development of asphalt pavement technology.
"Bridge doctor" shortens the time for detecting and sealing the road Our bridge rapid load test study has reached the international advanced level, which greatly shortens the time for detecting and sealing roads. “The secretary of the board of directors said that the bridge maintenance department now needs to regularly carry out “physical examinations†on the bridges to assess the health status of the bridges, and the main method is to use conventional load tests.
Pan Lingsong gave an example for reporters: “The Shanghai-Nanjing Expressway, for example, charges about 10 million yuan a day on the expressway. If a certain bridge on a highway is subjected to conventional load test methods for carrying capacity assessment, it needs to be interrupted. About eight and a half hours of traffic, the direct economic loss will be about 3.33 million yuan. Even if it is half-closed, there will be a loss of 1.6 million yuan per day. This is not due to the increased cost of the route that many vehicles are forced to bypass. Time costs and other indirect economic losses and the resulting huge social costs."
“If a quasi-static load test is performed on a bridge over a freeway, then only one or two hours of closed traffic is required. The direct economic loss is about 1/8 to 1/4 of the loss caused by the conventional load test method, and As a result, the additional losses caused by closed traffic will be greatly reduced."
According to the experts of the Soviet Bureau of Communications, the use of the research results of the SJIT can provide a reliable technical guarantee for the safe operation of the bridge and avoid the occurrence of major bridge accidents; it can reduce the disruption of traffic and effectively reduce the bridges in the traffic lifeline due to disruption of traffic. The huge economic losses it brings can also provide an effective basis for prolonging the service life of bridge facilities and reducing the huge maintenance and maintenance costs of bridge facilities. “This method has huge economic and social benefits and has broad application prospects.†The reporter learned that a number of scientific and technological achievements and new materials with international and domestic leading levels developed by SJT have been widely used in the Beijing-Shanghai high-speed Highways, Hong Kong-Zhuhai-Macau Bridge, Sutong Yangtze River Bridge and other national and provincial key projects. Su Jiaoke set up an open technology platform such as the “Key Laboratory for Bridge Health Testing and Diagnostic Technologies for Transportation Industry†and the “Public Service Platform for Bridge Quality Inspection and Operational Safety Evaluation in Jiangsu Province†set up by the Ministry of Communications. The academic committee composed of experts, in order to achieve a high starting point, a high level of development, and strengthen the strategic cooperation with the international, has cooperated with the world-renowned bridge research and consulting agency Danish Coway to research "long-span bridge detection technology", and Japan's Hanshin road The public corporation cooperates to study the “Bridge Maintenance and Maintenance Technology under Natural Disastersâ€; with the research and development of R&D, remote sensing, GIS application, and simulation of Japan PASCO Co., Ltd., an international leader in remote sensing and mapping technology, to realize high-end research The connection of resources.
