China adopted the reform and opening up has made significant achievements in economic construction has made remarkable achievements. In order to better implement the principle of taking economic construction as the center, China made a lot of investment in road traffic. Pass-Shenyang Expressway state Department of Transportation to revitalize the northeast old industrial base of Highway and Waterway Development Plan \the channel is one of the mountains of southeastern Jilin Province's first expressway. The opening of this highway through Shen journey time for half an hour, living in the mountains of Tonghua have an \It was opened to traffic, will greatly shorten the Tonghua Shenyang urban economic circle and the Bohai economic circle of the temporal and spatial distance, the end of Tonghua domain highway history, also marks the construction of a regional transport center in Tonghua made significant progress. The same time, due to the rapid economic development, the traditional asphalt road issued a major challenge. In this paper, through Shenyang Expressway project SBS modified asphalt, modified asphalt types, select modifier principle. Ultimately, through Shenyang Expressway select the rationality and necessity of SBS modified asphalt, and how to reach the best quality control of the construction process. Highway construction quality is directly related to its life in Jilin section through Shenyang Expressway construction process technology research. First, the analysis of the type of modifier studied the principle of selection of the modifier. The main purpose is to use a modifier to improve or enhance the performance of the asphalt pavement, different doses of the type of modifier or the same modifier, the modified asphalt will receive varying degrees of improvement. Due to the significant difference between the various modified asphalt type indicator itself, the modifier is not the same standard. Specifically, for high temperatures throughout the year, the weather was hot area, with a focus on improving the high temperature stability of the road, use SBS, PE, EVA and other modifiers can achieve better modification effect [1]; low temperature cold northern region, will focus on improving the low temperature crack resistance of the road surface, the use of SBS, SBR modifier can achieve good modification effect. Is not consistent due to the processing conditions required by the different types of modifiers, so to take into account the construction site with the processing conditions, and select the modifier and modification method in accordance with the actual circumstances. the ability to deform; through Shenyang Expressway construction site for processing modified asphalt equipment supporting the technology is relatively mature, so I decided to use SBS modifier, the production of SBS modified asphalt concrete to concrete pavement. material selection, with construction machinery, construction process control and quality inspection process, detailing how the project combined with the project itself for proper selection, reasonable construction. Details through Shenyang Expressway construction SBS modified asphalt mixture storage, mixing, transportation, paving and other sectors, and to study how the control of all aspects of the construction process, to improve the performance of modified asphalt pavement. After the completion of the asphalt pavement testing, and test results to be analyzed. After nearly two years of observation, the road is in good condition, used in the construction process is feasible in the Northeast region.
