EXHIBIT C – ADDITIONAL WARRANTY REQUIREMENTS

1       WARRANTY REQUIREMENTS
This Exhibit C describes the warranty requirements for the Project. The Contractor shall provide warranties
to Mn/DOT against defects in materials and workmanship. The Contractor shall warranty its workmanship
and materials as specified herein.

2       WARRANTY SPECIFICATIONS
2.1     Flexible Pavement: New or Reconstructed Hot-Mix Asphalt
Evaluation Method. Mn/DOT will measure and quantify pavement condition parameters by evaluating
certain selected segments of pavement. A pavement segment is defined as any consecutive 500-foot section
of driving lane and/or shoulder. The pavement segmentation scheme (i.e., the segment termini) and the
pavement segment selected for evaluation will vary according to the condition parameter being evaluated.
Evaluation will include use of Mn/DOT’s pavement management system and/or field pavement condition
reviews.
Application. This section applies to pavement Warranties on new and reconstructed hot-mix asphalt (HMA)
pavement placed on an unbound or stabilized aggregate base. Distress identification must be according to
the Mn/DOT Distress Identification Manual and the following definitions.
Limits of Warranted Work. The Warranted Work shall include all HMA on driving lanes and shoulders
within the Project limits.

Condition Parameters. Condition parameters are used to measure the performance of the HMA pavement
during the Warranty term. Each condition parameter has a threshold level applied to each segment before
corrective action (Warranty Work) is required.

Definitions
   Transverse Cracking: A crack that is predominantly perpendicular to the pavement.
   Longitudinal Cracking or Open Joint: A crack that is predominantly parallel to the pavement centerline.
   Block Cracking: A pattern of cracks that divides the pavement into approximately rectangular areas that
     range in approximate size from 1 to 100 square feet.
   Fatigue Cracking: A series of interconnected cracks in the early stages of development, evolving into
     many-sided, sharp-angled pieces, usually less than one foot on the longest side, with a characteristic
     chicken-wire or alligator pattern.
   Debonding: A physical separation of the new pavement surface from the underlying pavement surface
     (visually identified by shoving or the loss of new surface course); includes surface potholes (regardless
     of depth) to the extent derived from debonding of the new surface course.
   Raveling: Wearing away of the HMA pavement surface caused by the dislodging of aggregate particles
     and loss of asphalt binder.
   Flushing: Excess bituminous binder on the pavement surface, which may cause a shiny glasslike
     reflective surface that may be tacky to the touch; usually found in the wheel paths.
   Popout: A small piece of pavement or aggregate greater than 0.25 inch in diameter that has broken loose
     from the surface.

   Rutting: A longitudinal surface depression in the wheel path; may have associated transverse
     displacement.
Threshold Limits. Table C-2.1 lists the allowable threshold limit for each condition parameter within each
pavement segment. If any threshold limit is exceeded as a result of a defect in materials and/or
workmanship, corrective action (Warranty Work) will be required. The defective segments for surface
distress do not have to be contiguous to necessitate corrective action. Each driving lane and shoulder must
be evaluated independently. Any pavement surface requiring removal or replacement to correct deficiencies
for any condition parameter must be placed full-width across the driving lane or shoulder.

Corrective Actions. Table C-2.1 suggests corrective actions to illustrate acceptable treatments for the
various condition parameters. Mn/DOT will Accept the listed corrective action if the action addresses the
cause of the distress. Contractor may implement Mn/DOT-suggested corrective action or an alternative,
subject to Mn/DOT Approval.

2.2     Rigid Pavement: New or Reconstructed Concrete
Evaluation Method. Mn/DOT will measure and quantify pavement condition parameters by evaluating
certain selected segments of pavement. A pavement segment is defined as any consecutive 300-foot section
of driving lane and/or shoulder. The pavement segmentation scheme (i.e., the segment termini) and the
pavement segment selected for evaluation will vary according to the condition parameter being evaluated.
Evaluation will include use of Mn/DOT’s pavement management system and/or field pavement condition
reviews.

Application. This section applies to pavement Warranties on new and reconstructed jointed plain concrete
pavement placed on an unbound or stabilized aggregate base course. Distress identification must be
according to the Mn/DOT Distress Identification Manual and the following definitions.

Limits of Warranted Work. The Warranted Work shall include all jointed plain concrete pavement on
driving lanes, ramps and shoulders within the Project limits.

Condition Parameters. Condition parameters are used to measure the performance of the concrete pavement
during the Warranty term. Each condition parameter has a threshold level applied to each segment before
corrective action (Warranty Work) is required.

Definitions
  Cracking: A visible fissure or surface discontinuity that may or may not extend through the entire slab;
    singular or in multiple patterns. Crack types are:
   - Transverse: Cracks that are predominantly perpendicular to the pavement centerline.
   - Longitudinal: Cracks that are predominantly parallel to the pavement centerline.
   - Corner: A portion of the panel separated by a crack that intersects the adjacent transverse and
       longitudinal joints, describing approximately a 45-degree angle with the direction of traffic, and with
       the length of the sides ranging from one foot to one-half the width of the panel on each side of the
       corner.
   - Map: A series of cracks that extend only into the upper surface of the slab; for larger cracks,
       frequently oriented in the longitudinal direction of the pavement and interconnected by finer
       transverse or random cracks.
   - Shrinkage: Partial-depth drying and plastic shrinkage cracks resulting from tensile stresses.
 Joint Spalling: Cracking, breaking, chipping or fraying of the panel edges within two feet of the
    transverse or longitudinal joint.
 Joint Sealant Damage: Any condition that enables incompressible materials or a significant amount of
    water to infiltrate the joint from the surface; typically, extrusion, hardening, adhesive failure
    (debonding), cohesive failure (splitting), and complete loss of sealant.
 Shattered Slab: A pavement slab broken into four or more sections by full-depth cracks.
 Scaling: Deterioration of the upper concrete slab surface, greater than 0.125 inch in extent, and occurring
    anywhere on the pavement.
 Popout: A small piece of pavement greater than 0.25 inch in diameter that has broken loose from the
    surface.
 Nonfunctioning Joints: Transverse panel joints with misaligned dowel bars or dowel bars that do not
    function as designed.
Threshold Limits. Table C-2.2 lists the allowable threshold limit for each condition parameter within each
pavement segment. If any threshold limit is exceeded as a result of a defect in materials and/or
workmanship, corrective action (Warranty Work) will be required. The defective segments for surface

2.5 Steel Paint Systems
Evaluation Method. Mn/DOT will measure and quantify bridge condition using the Pontis Element
Condition Ratings system outlined in the Mn/DOT Bridge Inspection Manual. All bridge components will
be evaluated on their ability to meet a Condition State 1 and the requirements described within this Exhibit
C. If a condition state is not present in the Pontis system for an element Mn/DOT will work with the
contractor to establish the Condition State 1 for aid element. Evaluation will include use of Mn/DOT’s
Bridge inspection program.

Application. This section applies to all steel paint systems used on ornamental metal railings and structural
steel members.

Limits of Warranted Work. The warranted work shall include all structural members and steel ornamental
railing.
Condition Parameters. Condition parameters are used to measure the performance of the paint systems
during the warranty term. The following condition parameters apply.
Definitions
  Visible Rust or Rust Breakthrough: Any corrosion of the steel member
 Paint Blistering: Areas in the paint system where the paint has bubbled or loosened from the steel
   member
 Peeling and Scaling: Areas in the paint system where the paint is no longer adhering to the steel member,
   causing loss of paint system
 Chalking: White or gray surface imperfection, apparent from discoloration of surface

Threshold Limits. Table C2-4 lists the allowable threshold limit for each condition parameter. If any
threshold limit is exceeded, corrective action (Warranty Work) is required.

Corrective Actions. Table C2-4 suggests corrective actions to illustrate acceptable treatments for the various
condition parameters. The Mn/DOT will accept the listed corrective action if the action addresses the cause
of the distress. The Contractor may implement the Mn/DOT-recommended corrective action or an
alternative, subject to Mn/DOT Approval.

2.6     Differential Settlement of New Roadway Grade (Including Bridge Fills)
Evaluation Method. Mn/DOT will measure and quantify differential settlements in accordance with the
Condition Parameter conditions listed below.

Application. This section applies to settlement Warranties on all new roadway and ramp subgrades
constructed within the Project limits.
Limits of Warranted Work. The Warranted Work shall include all subgrade excavation, embankment, and
aggregate base placed on the roadway below the pavements, including bridge approach panels and pavement
over culverts and utilities.
Condition Parameter. Condition parameters are used to measure surface differential settlement in the
pavement. The differential settlement will be measured (both along the roadway profile and transversely
between lanes, shoulders, and adjacent structures) using a straight-edge, 25-foot California profilograph,
and/or the Mn/DOT’s pavement management distress van (i.e., analyzing the van data to emulate the
profilograph measurement).

Threshold Limits. Table C2-5 lists the allowable threshold limit within each pavement section. If any
threshold limit is exceeded, corrective action (warranty work) is required. The defective segments for
surface distress do not have to be contiguous to necessitate corrective action. Any pavement surface
requiring removal or replacement to correct deficiencies for any condition parameter must be placed full-
width across the driving lane, shoulder, or ramps.
Corrective Actions. Table C2-5 suggests corrective action to illustrate acceptable treatment for the condition
parameter. The Mn/DOT will accept the listed corrective actions. The Contractor may implement the
Mn/DOT-suggested corrective action or an alternative action, subject to Mn/DOT approval.
