BACKGROUND The City has two annual projects designed to maintain roadway infrastructure. One of these projects is the resurfacing of various roadways by overlaying existing pavement with a new layer of asphalt concrete, while the other project is slurry sealing a different set of roadways as preventative maintenance. The street resurfacing component includes installing a new layer of asphalt concrete over the existing pavement, repairing pavement distressed areas, crack sealing, adjusting manholes and water valve boxes to grade, installing pavement markers, and installing traffic detector loops. The roadway preventative maintenance component includes preparatory work for the upcoming slurry seal project (CIP No. 18504). The preventative work will include sealing pavement cracks and repairing pavement distressed areas. This preparatory work is generally required prior to the start of the slurry sealing operation, and is included under the project in order to realize cost savings and for optimal results. The slurry seal project is scheduled to begin construction upon the completion of this project's preventative maintenance component. DISCUSSION The first component of the project consists of approximately 1.2 million square feet of pavement resurfacing on the streets listed in the table below. Depending on the condition of the existing street, one of the two maintenance methods listed below are used. The column on the right of the table indicates the treatment that will be used on each street section. Overlay (OL): This construction method involves grinding the edges of the existing pavement, and placing a new surface course of 1.5 to 1.75 inches of new asphalt concrete over the top of the existing pavement. Grinding the edges is necessary to conform the new overlay with the existing curb and gutter. Overlay with Fabric (OL/F): This construction method involves grinding the edges of the existing pavement and placing a layer of paving fabric on the pavement prior to applying a new surface course of 1.5 to 1.75 inches of new asphalt concrete over the top of the ex'sting pavement. The paving fabric is needed when the existing pavement has cracking caused by heating and cool cycles. The paving fabric "bridges" these cracks that are only in the surface layer. Without the fabric, the cracks would quickly propagate to the surface of the new pavement. This is known as "reflective" cracking.
