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
