BLOOMINGTON — Portions of 70 streets and alleys in Bloomington will be improved through the city's pavement preservation program, beginning Oct. 14.
"Pavement preservation is a cost-efficient way to stretch the life of existing pavements," said Bloomington Public Works Director Jim Karch. "It makes sense to get the most life that you can out of our existing streets.
"With streets the important thing is to use the right treatment at the right time to get the most out of your pavement life. Pavement preservation is one of these important treatments that is used."
Residents on those streets should anticipate parking restrictions through Oct. 25 while the work is being done.
Temporary "no parking" signs will be placed in the blocks on each of the streets, and restrictions will be in effect from 7 a.m. to 5 p.m. Driveway access on each street will be restricted for up to 30 minutes unless there is an emergency.
A complete list of the streets and map of the planned resurfacing projects is available at www.bloomingtonstreets.com.
"The city will be doing almost $420,000 of preservation work but that includes work on the roads around Lake Bloomington as well," said Karch. "The $375,000 is for the preservation work done in the city."
In August, the City Council approved an agreement with Corrective Asphalt Materials LLC, which is the sole distributor and applicator of the two types of pavement preservation used by the city: Reclamite and C85.

Reclamite uses emulsion made up of specific petroleum oils and resins. The process keeps the pavement flexible, so both cracking and road fatigue are reduced.
C85 is a seal for asphalt that has deteriorated beyond the point where Reclamite alone is an effective treatment. The seal uses a petroleum-based emulsion product that is covered with lime chips. The product is designed to be kneaded into the surface by vehicular traffic once it has been applied.
Money will be transferred from the city's new concrete and asphalt fund that was created earlier this year.
The revenue generated by the now 8-cent local motor fuel tax and from a fourth of the city's 1 percent home rule sales tax is kept in the special fund so that it can only be utilized for concrete and asphalt projects.
Those funds collected this fiscal year to date total $1,812,406. Expenditures total $567,819, but that amount does not include the pavement preservation cost since the project hasn't been paid for yet, said Karch.
In addition to the pavement preservation work, the city, during this construction season, is resurfacing 18 streets and an alley. The council approved $5 million in contracts to resurface those streets and repair sidewalks.
