Abstract: The quality of subgrade construction has the most direct impact on the safety and stability of high-way. In this paper, the green design concept is applied to the basic principles of highway subgrade design, and effective measures are put forward for the process of highway subgrade design. Thus, how to apply the green design concept in highway subgrade design is discussed in detail, which provides a reference for the future green highway subgrade design. 

Keywords: Subgrade construction; Green design concept; Effective measures
