The Village of Hoffman Estates, Illinois recently opened bids for transportation projects and announced that coal tar sealants would not be used on the 2011 Crack Sealing and Seal Coating Project:
As a part of ongoing environmental reviews and recent industry concerns, the Village chose to steer away from the traditional coal tar based seal coating products used in the past in favor of an asphalt emulsion sealer.
The contractor awarded the bid was within the engineer’s construction cost estimate. Contrary to what some have stated, budgets were preserved and no negative impact to business took place in the use of an alternative sealant product.
