Best Practices for Pavement Edge Maintenance Research Report;Research rept. 1 Sep 01-31 Aug 03

摘要

The objectives for this research-to identify and to effectively communicate best practices for pavement edge maintenance-were accomplished by capturing over 3700 years of institutional knowledge from maintenance leaders representing all 25 Districts of TxDOT. The research focuses on maintenance practices for naturally-occurring edge drop-offs with an emphasis on low-volume roads. The key factors causing edge drop-offs are narrow road width/absence of shoulders, traffic volume/type, and adverse environmental conditions. Edge maintenance practices and procedures fall into three broad categories: awareness, preventive maintenance, and edge repair techniques.
