Durability Analysis of Aluminized Type 2 Corrugated Metal Pipe

摘要

The focus of field studies conducted during this investigation centered on theperformance of alumized Type 2 culverts. Of the 32 culverts inspected during this investigation, 21 culverts were part of a previous Federal Highway Administration (FHWA) study. These culverts were located in Alabama and Oregon. Eight culverts at five sites in Maine were added with the expansion of these field studies. In situ field measurements of pH and resistivity were taken at each culvert. The abrasive situation at each culvert was characterized, including slope, flow velocity, and abrasive material. Each culvert was photo-documented and many were videotaped for future reference. Coupon samples were taken at each location for pit-depth analysis. Soil samples were removed for laboratory resistivity measurements.
