California County seeks rubberized asphalt grant
San Diego County in California
is progressively dealing with the ban on landfilling whole tires.
The County Board of Supervisors recently cast a unanimous vote
to request a $50,000 grant from the California Integrated Waste
Management Board to offset the county’s rubber asphalt project.
The expected cost of the project is as high as $5 million and
could go higher.
The county began a pilot project
in 2002 to test the results of rubberized asphalt. The results
showed a definite improvement on not only maintenance considerations
but also in noise reduction – a decrease in road noise of
four to six decibels.
In order for the project to receive
grant funds, the concrete content must contain crumb rubber created
from waste tires in California and the project must be large enough
to utilize 2,500 tons of paving material.
