Design Strategies for Roadbed and Pavement Based on the Goal of Green Highway Construction

Abstract

This article takes the reconstruction and expansion project of the Tianjin section of the Beijing-Tianjin-Tanggu Expressway as an example to systematically explore the design strategies for roadbed and pavement under the goal of green highway construction. During the research, after discussing the goals and policies of green highway construction in Beijing, in-depth research was conducted around the design of protective support engineering, soft foundation treatment, comprehensive utilization of earthwork, drainage systems, and pavement design to explore how the case project can achieve high-quality design based on the goal of green highway construction. It is hoped that this article can provide technical reference and value for China’s road and bridge engineering design and construction units, providing a low-carbon practice paradigm for the integration of Beijing-Tianjin-Hebei transportation, while promoting the sustainable development of China’s green highway concept.
