AbstractCombining with the old road reconstruction project of a highway construction in the Loess Plateau and the reconstruction design of some cross roadsthe advantages and disadvantages of different reconstruction schemes were analyzed and compared in terms of technologyeconomy and environment. In view of the complex terrain and the fragile engineering geological conditions in the Loess Plateaureasonable design schemes of old road reconstruction were determined flexibly by horizontal and vertical index,which will provide reference for the old road reconstruction of the highway construction.
