catch basins, and manhole covers. An advantage of using rubberized asphalt for a newly constructed structural section of roadway is the expected increase in longevity of the roadway section compared to conventional asphalts. While actual design lives have not been determined for rubberized asphalts, the life cycle is conservatively estimated to add 3-5 years to the life of the pavement. However, this project is not a replacement of a new pavement section, but a 2" overlay over an existing 4" conventional asphalt section, and therefore the expected additional life added is unknown. In comparing the costs for the two sound attenuating pavements, the contractor's cost for the 2" rubberized asphalt is $115.00 per ton of asphalt verses $87.00 per ton for the open graded mix asphalt concrete. Based on the anticipated quantities, the increase in cost to install rubberized asphalt instead of open graded asphalt is $120,000. As a means to offset some of the increased cost over conventional asphalt, the City applied for and was successful in obtaining a grant from the Integrated Waste Management Board in the amount of $6,750. This would reduce the increased costs for rubberized asphalt from $120,000 to $113,350. However, due to the increased costs, the limited benefits for extending the pavement life cycle, and essentially the same noise reduction properties as open graded mix asphalt, the rubberized asphalt alternative is not recommended. Therefore, staff recommends the use of open graded mix asphalt as the pavement of choice for sound attenuating pavement. Bid Opening Sealed bids for this project were opened on December 12, 2006.
