    PAVEMENT CONDITION INDEX

    A Chip Seal is an evenly distributed layer of emulsified asphalt placed on an existing surface.  Then a single layer of graded aggregate is embedded into the oil, rolled, swept and fog sealed.

    Most cost effective process for maintaining asphalt

    Emulsion helps to seal minor cracks and slows water penetration

    Quick application

    High friction surface creating a safer road

    Double Chip Seal is two layers of Chip Seal stacked on top of each other.

    Very durable and flexible – significantly reduces cracking Quick application (both layers)Gives extra life to the roadSolution for deteriorated pavements where budget constraints exist, and a single chip seal is not enoughIdeal application for gravel roads

    Hot Chip Seal combines a Chip Seal and a thin lift of open graded friction course (OGFC) providing a double application of material.  The Chip Seal provides a water resistant membrane and the Hot Chip Seal provides a wearing surface that will improve the profile of the existing asphalt.

    Asphalt pavement needs structural strength Enhances road for a smoother ride Quiet surface treatment Improves skid resistance Great for use on high‐volume traffic roads Less expensive than a mill and overlay Rock on rock construction – extremely durable Long‐term investment strategy

    Let contracts early in the yearAllow for flexible schedule if possible, otherwise determine a specific timeline

    Determine proper specifications for type of roadwayRequire state of the art equipmentTest all aggregate for proper gradationsTest all aggregate to make sure it meets 3:1 or 12% flat and elongated specification

    Verify material tickets for proper application ratesEnforce weather requirements
