Kentucky getting warmer…

Nov 30, 2010

Plantmix Asphalt Industry of Kentucky (PAIKY) has announced that they met with the Federal Highway Administration (FHWA), Kentucky Transportation Cabinet (KYTC) and various paving contractors to consider using warm mix asphalt at temperature limitations beyond those currently outlined in Kentucky’s standard specifications book. Kentucky's current specifications require a minimum ambient air temperature and minimum surface temperature prior to asphalt placement. The KYTC and FHWA are in agreement to consider requests to lower those temperature limitations on an experimental basis for warm mix asphalt only. On a trial basis, the KYTC may allow lowering the temperature limitations for base warm mix asphalt to 33 degrees Fahrenheit and surface warm mix to no less than 35 degrees Fahrenheit. All other specification requirements must be met. Approval for this experimental change will be granted on a project-by-project basis. Evotherrm was used in several projects in Kentucky this year so we’re excited about the potential of an expanded paving season there.
