plants
__________________________________________________________________________ Apply Release Agent at the Plant Over application of water based release agents can cause steam stripping of aggregate and create cold spots in the load due to excessive pooling. Do Not Allow Trucks to Clean Out on Grade In Front of Paver A quality release agent mitigates the need for most clean out sites. Direct Trucks to a Location Where They Can Clean Out and Material Can Be Managed Apply Release Agent to Paver to Provide a Lubricating & Cleaning Action Diesel fuel strips the binder and creates and environmental and safety hazard.

__________________________________________________________________________ Utilized as a Drag Chain Lubricant and Cleaner Avoid Costly Fires by Preventing Diesel Usage Reduce Down Time and Minimize High Start-Up Amperage
__________________________________________________________________________ Dribbling Material is Prone to Segregation Cooler Crust Doesn’t Mix with Hot Load Truck Bed Mix Buildup Creates a Friction or Drag Zone That Impedes the Normal Flow of Mix Into the Paver
__________________________________________________________________________ Asphalt Buildup Creates Inefficiencies Increases Costs Due to Cleanout Time and Contracted Trucking Problems Contributes to the Abuse of Diesel Fuel Worn, Dented Beds Provide an Area for Sticking and Pooling of Water Based Release Agents
__________________________________________________________________________ Reduces Carry Load of Fresh Asphalt Increases Per Ton Costs Due to Decreased Carrying Capacity of Trucks Excessive Wear on Truck Beds Due to Hammering and Scraping
__________________________________________________________________________ Asphalt Buildup Hardens and Breaks Off Cold Blocks Do Not Mix Into a Homogenous State Cool – Hard Asphalt Creates Mat Defects
__________________________________________________________________________ Cost Effective Solutions Provide Multiple Loads on a Single Application Eliminate Diesel Abuse Increase Efficiency
__________________________________________________________________________ Large Volumes of Material Dumped or Spilled by Trucks Compacted Pile Thicker than Mat Creates Potential Smoothness Issues Costly Cleanup Expenses for Cleanout Piles Alongside Paving Job
__________________________________________________________________________ Mat Shows Open Texture Thermal Image Shows Cold Spot Uneven Compaction and Poor Ride Smoothness Bonus Could Be Affected
__________________________________________________________________________ Release Agents Applied to the Paver Provide a Cleaning and Lubricating Action Diesel Fuel Use Degrades the Mix Design Diesel is a Skin Irritant and Pollutes the Environment When Used as a Cleaner and Release
__________________________________________________________________________ High Spots Caused by Material Dumped on Grade Trucks Clean Out Pulling Away from Paver Inadequate Release Agents Contribute To Sticking and Buildup
__________________________________________________________________________ Small Volumes of Uncompacted Mix Cause Defects Cold Mix Creates Temperature Variations
__________________________________________________________________________ Fresh Mix Laid Over Cold Piles Cold Mix Just Under Surface Or Partially Exposed
__________________________________________________________________________ Small, Compacted Pile Usually Not Visible in Mat Surface Uneven Compaction Bump Fractured Aggregates
__________________________________________________________________________ Pile Compacted by Truck or Paver Tires May be Completely Covered by Mat, Depending on Thickness
__________________________________________________________________________ Mat May Not Show Any Visual Defect Thermal Image Shows Cold Pile Spread by Screed From Small Pile of Cold Mix Uneven Compaction Results May Result in a Bump
__________________________________________________________________________ Non-Stick Emulsions and Soap Solutions Help Prevent Pick-Up Hand Held Sprayers or On- Board Water Spray Apply to Clean Tires Before Rolling Begins Discontinue After Tires Heat Up Re-Apply if Tires Cool
__________________________________________________________________________ Tires Too Cool, Stay Close to Paver Apply Release Agent to Prevent Tire Pick-Up Keep Tires Hot Use Tire Skirts Some Contractors Use Tire Heaters Radial Tires Pick-Up Less
