Abstract


With the recent rapid economic development of our society and the rapid growth of vehicle ownership, the early part of the construction of trunk highway traffic has become saturated, freeway expansion project is the important issues facing to road construction. For the reasons of the new-building is distinct from rebuilding, freeway research has important practical significance.In this context, the papers determine the focus of this study by finishing the success of national reconstruction and extension project and the related literature examples. First paper on the expansion project of the construction standards for studies to determine the scale of reconstruction and extension and technical standards; Second paper combines the flat, vertical and horizontal design of the main technical indicators, shows the expansion project for the design and longitudinal plane fitting method of fitting design, and the main geometric cross-sectional design of the facility to make correlation analysis, and cross-sectional geometry of the main design of the facility to make correlation analysis; Finally, the structure of the cross-sectional form widening of comparison, the same time, unilateral widening of the median were targeted research.This paper studies the country successfully through the renovation and expansion project and the difference between the new highway and expansion of highway design level aspect, proposed ideas and methods. Old freeway extension route is designed to make a certain contribution to the standardization.
