Answering critical infrastructure questions
Neil Hoult and Ian Moore,Department of Civil Engineering
Outline
Three example projects:
• Deteriorated culvert testing• Rehabilitated culvert testing with novel sensors• Field test of a bridge
Future facilities
Deteriorated Culvert Testing
Objectives:• Determine capacity of deteriorated culverts
Impact for partner:• Optimize rehabilitation / replacement strategies
Partners:• Ministry of Transportation Ontario (MTO)• National Cooperative Highway Research Program
(NCHRP)

Rehabilitated Culvert Testing
Objectives:• Determine capacity of rehabilitated structures
Impact for partner:• Develop accurate procedures for rehabilitation design
Partners:• KWH Pipe• Lafarge• Ministry of Transportation Ontario (MTO)• National Cooperative Highway Research Program (NCHRP)• Ontario Concrete Pipe Association
Fibre Optic SensorsPurchased with CFI, MRI and industry funding
• Optical Backscatter Reflectometer (OBR 4600) developed by Luna Technologies
• Allows for distributed measurements of strain
• Characterize behaviour in a way that has not been possible
Pipe Rehabilitation using slip lining
Novel Measurements – HDPE Liner
Bridge Field Testing
Objectives:• Develop tool for assessment and damage
detection in bridges
Impact for partner:• Extend bridge service lives
Partners:• Ministry of Transportation Ontario• Transport Canada
Test Site: Black River Bridge
Fibre optic layout
Fibre optic vs strain gauge measurements
Bridge response
Future FacilitiesFunded by CFI, MRI and industry
Geotechnical Testing – water and sewer pipes, culverts• Deep burial and erosion simulator• Pipe deterioration facilities• High speed distributed strain measurement (?)
Structures• Moving load simulator• Deterioration facilities• Bridge component testing
