LT Warranty Concept
Why 7-Year Pavement Warranties?
• Move toward performance specifications• Reduce contract administration, pay items,
inspection and testing costs• Encourage innovation • Reduce overall project and lifecycle costs• “7” years provides confidence that the 18 -
20-year service life will be achieved
Project Selection
• 2 lane and 4 lane rural highways with less than 5,000 AADT/design lane
• Uniform pavement performance without extensive problematic soils/swamp conditions left untreated
• Normally less than 100 km from a permanent HMA plant
Categories of Warranty Projects
• Two Categories– Rehabilitation– Reconstruction
Pavement “Rehabilitation”
• Treatment of some or all the existing materials from the top to the bottom of the existing bituminous layers
Includes:
– Partial or full depth asphalt removal with resurfacing
– Cold in-place recycling with asphalt resurfacing
Pavement “Reconstruction”• Treatment of all existing bituminous layers and a
minimum of 150 mm of the underlying granular materialIncludes:– removal of all bituminous layers and some or all of the
granular material and replacement with new or recycled materials
– full depth in-place reclamation to a minimum depth of 150 mm into the granular, with or without milling or stabilization, with asphalt resurfacing
MTO Design Responsibilities
• The usual ground survey and geotechnical field data is collected
• MTO designs:– the alignment and final cross-section of the hwy– special treatments to widen the roadway subgrade or
stabilise shoulders and embankments– ditches, culverts, frost heave treatments – any other non-pavement work included in the project
Principles of Pavement Warranty Projects• The contractor is responsible for the pavement design,
materials and workmanship
• The warranty is on pavement performance for a fixed period of 7 years
• Minimal material requirements are specified. Standard specifications are not specified
• MTO’s pavement design is for internal use only
• The Contractor’s design is reviewed for compliance
Principles cont’d• One “Pavement with Warranty” lump sum item includes
all costs within pavement design envelope
• Info provided to Bidders: traffic level for design, surveys, soil borings, pavement cores, X–sections if applicable, past contracts if available
• Soils and pavement data is not guaranteed to be sufficient
• Field investigation by bidders allowed, preferably with no snow in ditches, during minimum 6 week advertising period
