Road barriers Maintenance and Repairing
When selecting a type of road barrier, the focus is often on safety performance and investment costs. Life-cycle costs are often ignored, mainly insufficient knowledge regarding Road barrier maintenance. The most frequent maintenance measure for road barriers is damage repair, mainly caused by vehicle collisions or impacts by snow removal equipment. Repair costs for barrier damages constitute a considerable share of road maintenance costs. However, such repair costs are seldom considered during road design and the subsequent selection of barrier types to be used. Limited information concerning repair costs and other influencing factors obstruct an adequate consideration of maintenance aspects when selecting a barrier type during the road design process.
This fact is confirmed by a study showing that one of the problems preventing sufficient consideration of maintenance aspects during the road planning and design process is insufficient knowledge regarding maintenance.
