An overview of intelligent construction and maintenance technology for highway subgrade engineering

Abstract

In terms of quality, functionality, and services, smart highways are an improvement over conventional highways and a crucial part of the latest infrastructure development. The primary load-bearing component of roadways is the subgrade. Accidents brought on by low-grade illnesses have been more common in recent years, yet it has been challenging to correctly diagnose low-grade illnesses in their early stages. Digital construction technology, intelligent construction, information management and control, and high-quality development as opposed to high-speed development are now the main technical tools used in subgrade engineering construction in China. This paper, which is based on the background of smart highways, analyzes the necessity and development prospection of intelligent construction and maintenance of subgrade engineering, proposes the development direction of intelligent construction and maintenance of subgrade engineering, and summarizes the relevant intelligent technologies throughout the lifecycle of subgrade engineering.
