Title: Maintenance And Repair Of Bridges
Author(s): Conde B. McCullough
Publication: Journal Proceedings
Appears on pages(s): 229-256
Abstract:Maintenance costs for highway bridge structures are affected by a number of factors-original design adequacy, *traffic burden, local climatic conditions, and the character of the stream itself all play an im-portant part. Those major items of maintenance ex-pense for timber structures, steel structures, and struc-tures of plain and reinforced concrete are discussed with emphasis on reinforced concrete in areas of low temperature and heavy ice and snow (structures in that portion of Oreqon east of the Cascade Range) with many annual cycles of freezing and thawing. Specialized technique for waterproofing handrails, balus-trades and other exposed structural portions, and moderate-heat cement’ are used. Reports’ average unit costs for those items of expense ordinarily encountered in the maintenance of the various types of highway bridge construction, and treats of the effect of design details on bridge maintenance expense and the development of special low-maintenance structural types.
