10 LT Warranty Concept

11 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 year service life will be achieved

12 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

13 Categories of Warranty Projects Two Categories –Rehabilitation –Reconstruction

14 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

15 Pavement “Reconstruction” Treatment of all existing bituminous layers and a minimum of 150 mm of the underlying granular material Includes: –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

16 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

17 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

18 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
