Research On Pavement Performance Of Reactive Properties Of Mixture And Its Application In The Steel Bridge Deck

The orthotropic bridge deck pavement of long span steel construction is the most complex and critical technical issues,it Is a worldwide technical problems. This is a systematic project,related to mechanical analysis, material properties, construction techniques and other aspects of the study. Heavy traffic conditions for long span steel bridge deck pavement conditions on the use of orthotropic steel deck plate stress state put forward higher requirements of the basic strength of pavement materials, deformation, corrosion resistance, water stability, high temperature stability resistance, low temperature cracking resistance, adhesion, slip resistance, and resistance to fatigue cracking of the construction process.In this paper, take heavy traffic of steel bridge deck for the research background, learn at the home and abroad steel deck outstanding achievements deeply, combined entity works of Jiangyin Bridge Steel Bridge Deck. Early physical and mechanical properties of raw materials, developed for heavy traffic in large span steel bridge deck of modified epoxy binder in laboratory tests, numerical analysis, physical verification and other engineering tools. Considering pavement road performance, combined with engineering practice in the actual use of effects and past experience and reference SMA mix design ideas and principles, proposed a modified epoxy resin mixture mix design Methods RRC, combined analysis of leak tests, flying test, refered of the Marshall test results to determine the optimum binder content and recommended dosage range of binder paper; At the same time with the United States epoxy asphalt EA performance comparison test, study on the RRC modified epoxy resin mixture of high temperature stability, low temperature cracking type, fatigue properties, resistance to aging and other road performance; Reference to "Asphalt Pavement Technology Standards" relevant technical requirements ,according to the measured temperatures in different construction of modified epoxy binder viscosity growth curve results, combinating of local climate conditions, determined the best mixture of epoxy resin modified RRC Jiangyin Yangtze River Bridge deck pavement technology, formed a complete set of technology independent intellectual property rights in China.,Solve Heavy traffic durability of steel bridge deck problems.
