NYCDOT tries new asphalt overlays in search of cost-effective pavement for city ’s planned upgraded bus lanes.
By Paul Fournier
New York City’s Department of Transportation (NYCDOT) recently applied two trial thin-lift asphalt overlays to two sections of Manhattan’s 1st Avenue as the agency seeks cost-effective ways to resurface the entire roadway.
The City is currently upgrading bus lanes on busy 1st Avenue but the street’s 25-yearold Portland cement concrete (PCC) pavement is in poor condition and there isn’t enough money to completely replace the 18-inch-thick structure. Consequently, NYCDOT is looking for less costly alternatives to improve the street’s riding surface and decided to look at thin asphalt overlays as a possible solution.
