Surface Prep Matters When Temps Dip
Before takeoff, you must double-check the surface to be paved. In cooler temperature conditions, every minute spent cleaning a mess in front of the paver could mean a delay for trucks of perishable material waiting for paving.
Make sure the surface is clean before the trucks start arriving for the paving shift. Clean and dry the surface so you’re ready to go when the first haul truck arrives. If the surface has been milled, make sure the surface has been swept properly and tack (if applied) has been applied evenly, according to specified rates. If you’re using emulsified tack, you’ve got to give it time to break before paving begins—that means it’ll change color—and cooler temperatures will influence that timing.
Be aware of time and temperature any time of year, but especially when ambient temperatures could negatively impact your compaction goals.
