Description
Technical Field
The invention belongs to the technical field of aryl ether compositions, and particularly relates to a multielement polymer alloy steel bridge deck pavement material and a preparation method thereof.
Background
With the increasing importance of the country on the construction of the traffic infrastructure, the investment on the construction of the highway is continuously increased, so that the high-grade highway and the local highway have great development. Meanwhile, with the promotion of highway construction, the construction of highway bridges is rapidly developed in scale and speed which are exclamatory, and great achievement is achieved. Nowadays, bridges of different types and different spans, thousands of postures and disputes are shown on rivers, lakes, seas and expressways in China, and the refulgence of the traffic in China, particularly the construction of highway bridges is shown (the quality management problem analysis and countermeasure research of the road bridge construction project, Li Ke, the traffic world (transport vehicles), 11 th in 2012, 233 th in 232 th-. Currently, the achievements of bridge construction in China can be summarized as follows: the method realizes the purposes of large span, innovation of bridge structure and technology, mature deep-water large-span bridge construction technology and enhanced bridge aesthetic concept (the new chapter of bridge history written in China, Wang Yong Jie, China road, 9 th year in 2005, 18 th to 19 th pages, and 31 th 12 th and 2005).
Among tens of thousands of built bridges, a large number of large-span bridges appear, and the bridges with the span of more than 400m are built and have dozens of seats. Wherein, the most representative 4 span bridges are: the 423 m-span Shanghai Nanpu bridge built in 1991 is the first bridge in China with span over 400 m; the Shanghai Lupu bridge built in 2003 creates a new arch bridge world record in 550m span, and obtains the outstanding structure prize of the International bridge and structural engineering society in 2008; the world record of the span of the cable-stayed bridge is improved to 1088m by the cable-stayed bridge with the maximum span in the world, namely the Sutong Yangtze river bridge built in 2008; a1650 m-span Zhoushan West door bridge built in 2009 is a steel box girder suspension bridge with the largest span in the world at present, and a novel split type steel box girder technology is firstly adopted internationally to improve the wind resistance and the spanning capability of the steel box stiffening girder suspension bridge (the wind resistance technical challenge and basic research of the large-span bridge, the Nailai and the like, Chinese engineering science, 13 rd volume in 2011, 9 th pages from 8 to 20, 12 th and 31 th published 2011), the wind resistance technical challenge and the fine research of the large-span bridge, Kudzujun, engineering mechanics, 2011, A02 th pages from 11 to 23, and 2011, 12 th and 31 th published 2011).
For a large-span steel bridge, the asphalt pavement of the bridge deck is used as an important component of a bridge travelling system, and the safety, the comfort and the bridge durability of the travelling are directly influenced by the quality of the asphalt pavement (application research of epoxy asphalt concrete in the pavement of the steel bridge, white forever, the transportation world (construction and maintenance machinery), No. 6 of No. 173 of 2008, No. 145 and No. 146 of 2008, 12 and 31 days of 2008). With the continuous increase of bridge span, the structural weight is lighter and lighter, and the structural rigidity is smaller and smaller (analysis of bridge impact coefficient under the action of vehicles, Shandong, Chongqing university of traffic school newspaper (Nature science edition), volume 32, No. 1, pages 5-8 in 2013, published day 2013, 02 and 28 days; "research on wind resistance of large-span bridge", Gezuojun, engineering mechanics, No. A02, pages 11-23 in 2011, and published day 2011, 12 and 31 days in 2011).
The asphalt concrete pavement is widely applied to steel bridge deck pavement due to the aspects of short construction and maintenance time, strong driving safety and comfort, simple and convenient oxidation maintenance and the like (application research of epoxy resin concrete in steel bridge deck pavement, Li Jia Qing, Master academic paper of Changsha university, 2007, page 2, published day 2007, 12 and 31 days; "shallow precipitation asphalt concrete bridge deck pavement disease form and cause", Gong soldier, China science and technology Explorer, 2012, 22 nd, 351 nd, and 2012 and 12 and 31 days). However, the constant load of asphalt concrete is large, which increases the difficulty in constructing the steel bridge with an ultra-large span (research on bridge deck pavement materials and technologies of steel bridges, Tan Chun ren Zhi, university of Chongqing, university of Master academic thesis, 2008, page 1, 2008, 12 months and 31 days), thereby greatly restricting the development of steel bridge construction; on the other hand, the asphalt concrete has poor high temperature resistance, and the transverse tensile stress (strain) of the pavement layer is easy to cause cracking of the pavement layer, particularly longitudinal cracking under the action of a traveling load (mechanical calculation of the pavement layer of the composite pouring asphalt steel bridge deck, Zhuhuaping and the like, China engineering science, 15 th volume, 8 th volume, 60 th to 63 th pages, 12 th and 31 th days in 2013); meanwhile, the asphalt concrete has certain gaps, particularly the surface layer asphalt concrete has larger porosity, rainwater easily enters the surface layer, and the waterproof bonding layer on the surface of the steel plate is easy to age and lose bonding force under the action of harmful ingredients in the rainwater, so that the viscosity strength between the asphalt concrete layer and the surface layer of the steel plate is reduced. Therefore, most of steel box girder bridge deck asphalt concrete pavement layers at home and abroad have diseases such as transition, hugging and the like in different degrees less than the design year, and even some bridges can have the diseases after traffic is started for 1-2 years (the characteristics and cause analysis of highway pavement damage and roadbed diseases, Tangshuangmei and the like, China high and new technology enterprises, 15 th year in 2009, 172 pages 171 and 172 pages in 2009 in public, 12 months and 31 days in 2009; the high-viscosity modified asphalt SMA pavement technology is applied to the pavement of the steel box girder bridge decks, yellow bridge connection, northern traffic, 1 st year in 2013, 45 th-47 pages in 2013, 12 months and 31 days in public days). Therefore, it is of great significance to explore and search for new steel bridge deck pavement materials ("design of high-strength secondary light concrete and its application in steel bridge deck pavement", ding qing jun et al, construction technology, vol 36, 12 th of 2007, pages 64-66, published 2007, 12.31.12.2007).
At present, cast asphalt concrete, SMA and double-layer epoxy asphalt concrete are used as main paving modes for paving a bridge deck, and a cast asphalt concrete and SMA paving system has excellent low-temperature and fatigue performance but unsatisfactory high-temperature anti-rutting performance; epoxy asphalt concrete is excellent in high-temperature properties, but poor in low-temperature cracking resistance.
