This past year, Infrasense evaluated the condition of over 1000 bridge decks including nondestructive testing of decks in Wisconsin, Missouri, Florida, New York, Massachusetts, Connecticut, Indiana, Pennsylvania, Rhode Island, Idaho, Louisiana, Ohio, and Washington D.C.
ST. LOUIS (PRWEB) December 08, 2020
Infrasense recently evaluated the condition of 20 bridge decks primarily located in St. Louis and St. Joseph, Missouri. The deck evaluations were carried out using vehicle-based ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV) equipment operated at driving speeds. The GPR and IR methods are carried out according to ASTM specifications D6087-08(2015) and D4788-03(2013), respectively.
Following the field surveys, the data is transferred to Infrasense’s headquarters in Woburn, Massachusetts for quality assurance (QA) review, analysis, and reporting. The analysis is completed with the support of internally developed proprietary software. The software is specifically catered to the analysis of GPR, infrared, and visual data for bridge deck and pavement applications. For the Missouri bridge deck evaluations, the analysis resulted in quantities and maps of concrete delamination, deterioration, patching, spalling, and rebar cover. These results are delivered in a comprehensive report with descriptions of the data collection procedures, equipment, analysis methods, and results obtained.
This past year, Infrasense evaluated the condition of over 1000 bridge decks including nondestructive testing of decks in Wisconsin, Missouri, Florida, New York, Massachusetts, Connecticut, Indiana, Pennsylvania, Rhode Island, Idaho, Louisiana, Ohio, and Washington D.C. Infrasense methods have addressed a variety of bridge structure types, including asphalt, concrete, and epoxy overlays, stay-in-place forms, slab on girders, one-way slabs, and box girders. We have handled structures ranging in size from small 20-foot long stream crossings to major river crossings and viaducts up to 3 miles in length.
