Traditional Chain Drag Inspection Get in touch today to learn more Aerial IR Aerial IR Aerial Infrared Thermography Aerial IR is a powerful new tool for network level bridge deck evaluations Since 2019 Infrasense has analyzed thousands of bridge decks across 6 states Wisconsin Rhode Island Indiana Texas Alaska North Dakota Delamination detected by chain drag Advantages of Aerial IR Efficiency Hundreds of decks scanned per day Safety No exposure of personnel to traffic Accuracy IR results within 4 of chain drag on average 21 G Olympia Ave Suite 45 Woburn Massachusetts 01801 infrasense com Affordability A fraction of the cost of traditional inspections
When you inspect hundreds of bridges at a time the results may surprise you Aerial IR Data Validation 2017 Pilot Study with WisDOT found 86 correlation with vehicle based IR surveys performed according to ASTM D 4788 03 Aerial Inspection Comparison of Aerial IR and chain drag survey results on 70 Wisconsin and 14 North Dakota decks reveals delamination quantities to be within 4 on average Example 1 Unknowns NBI Deck Rating of 7 Aerial IR reveals 19 delamination Results later confirmed by DOT chaindrag survey Example 2 Underestimates Inspection report indicated 10 delamination Results Aerial IR reveals 33 delamination Delamination detected by Aerial IR Example 3 Inconsistencies NBI deck rating of 5 for both bridges Upper deck shows 3 delamination Lower deck shows 35 delamination Aerial IR provides clarity for existing inspection information Delamination With Aerial IR you have a record of the underlying data utilized to create the delamination maps so what you see is what you get Chain drag is prone to inconsistency and subjectivity take out the guesswork
