Steel Deck Epoxy Asphalt Pavement Construction Method And Quality Control

Epoxy asphalt material for its high plasticity material,can significantly improve the pavement layer bonding force and external force resistance,increase by deformation in the face of strong force,can bring significant resolve the upper load and lower rigid structure force damage,to enhance the durability of the bridge,in the current steel bridge engineering China has tried to a certain extent,and have achieved good results,but in the process there have been some problems,mainly reflected in the following aspects: for the epoxy asphalt deck surfacing process design and construction is not in place in the current period of epoxy asphalt deck pavement disease problems generally;therefore,take the bridge the pavement structure,appropriate and reasonable mixture ratio design and construction technology research,give full play to the performance of epoxy asphalt concrete has important engineering Significance?Based on the background of pavement engineering bridge in Ningbo city the second bridge,through the research of epoxy asphalt pavement construction,the second bridge concrete bridge deck pavement construction control,impact assessment of raw material properties,mixing process of epoxy asphalt mixture performance,the optimum Gus asphalt gradation of asphalt mixture by the amount of laboratory test and field test road paving,and then determine the mix of good design,through the construction process of experiment and construction after the supplementary test,reliability test,analysis of bridge deck pavement scheme and construction method,in order to provide guidance for the Daxie second bridge steel deck pavement,to further improve the relevant implementation plan of bridge deck pavement.Mainly include the following:First of all,this paper collects the characteristic of epoxy asphalt concrete and steel bridge deck pavement for research and application,and analyzes the development of pavement of epoxy asphalt deck,put forward the research contents and methods.Then,according to the requirements of the second bridge and the actual situation of epoxy asphalt concrete in Ningbo City,the reasonable selection of raw materials of epoxy asphalt mixture,and the properties of the raw material testing,in order to meet the relevant technical specifications.Third,the Marshall test method in epoxy asphalt mixture design used for high temperature stability,low temperature cracking of epoxy concrete and fatigue performance of epoxy asphalt mixture pavement performance and volume index were analyzed to determine the mixture mix ratio design system,and finally determine the gradation of epoxy asphalt the second bridge of concrete and the optimum asphalt aggregate ratio.Fourth,introduce the second bridge deck pavement engineering test section,from the preparation and construction of the testing section of adhesive layer spraying,mixture production to the mixture paving,according to the quality problems frequently encountered in construction,put forward suitable for bridge construction technology and construction of each link of Daxie bridge quality control method.Finally,according to the situation of the construction management pilot project construction management,from the angle of epoxy asphalt concrete,construction methods and organization management of epoxy asphalt concrete pavement quality,analyzes the second bridge,to ensure construction safety,environmental protection and other measures,provide a guarantee for the normal construction of epoxy asphalt concrete.
