Assessment of Pavement Damage Caused by Speed Bumps Along Nyanya – Jikwoyi Road Abuja
摘要
Unauthorized speed bumps installed by communities contribute to various problems such as road accidents, passenger discomfort, and potential pavement deterioration. This study focused on assessing pavement damage and the compliance of these speed bumps with design standards along the Nyanya – Jikwoyi road in Abuja utilizing the Pavement Condition Index (PCI) and a design guideline for traffic calming devices based on the City of Federal Heights, Colorado, the study examined variables including speed bump geometry, pavement distress types, severity levels, and their locations. Survey results revealed a significant interplay between speed bumps and pavement health, with 75% of sections showing moderate to high distress levels and an average PCI of 26.625, indicating poor pavement condition. Analysis indicated that 11 out of 34 speed bumps failed to meet the minimum spacing requirement of 121.92 m, highlighting design discrepancies. Additionally, only four surveyed locations had proper speed bump warning signs, suggesting a lack of adherence to safety standards. Recommendations include involvement of urban planners and traffic engineers in speed bump placement is suggested, along with routine pavement maintenance, especially in areas with high concentrations of speed bumps. Moreover, integrating speed bump placement into pavement design stages to deter unauthorized installations is proposed. In conclusion, this study underscores the importance of adhering to guidelines and involving professionals in speed bump placement to enhance road safety and pavement integrity.
