| Abstract: | Based on the case study of an expressway widening project, which tackles the problem with lengthways fissures emerged along the connecting lines between new and old roadbeds, this paper introduces the grouting technique using perforated steel pipe that is applied in the project. By comparing the treatment results for grouted area and non-grouted area using the dynamic probe method, it is concluded that roadbed reinforcement by means of perforated steel pipe grouting fully measures up to desired technical standards, and the result may serve as a reference for relevant engineering applications. |
