Item C: Review of Implementation of Street Bond Measure

PPP - Pavement Preservation Program. This is the current capital project program to preserve Eugene's improved street system. The priority for this program is to preserve streets that have not yet degraded to a point where reconstruction is required. Preserving a street through overlay or similar treatment is four to five times more cost effective than waiting to repair a street after it requires reconstruction. This program was initiated in 2003 and, until passage of the 2008 street re air bond was redominatel funded with p 1 p y Paving on Augusta Street local fuel tax and the reimbursement fee component of transportation system development charges. Warm Mix Asphalt - Warm mix asphalt pavement is identical to conventional hot mix asphalt pavement, except that through a special mixing process it is produced at a temperature approximately 50 to 100 degrees cooler than conventional hot mix asphalt. In Eugene, all asphalt concrete producers have retrofitted their plants to produce warm mix asphalt using a water foaming process. The foaming process allows temperature reductions of approximately 50 degrees. This reduction in temperature has several advantages: 1. Reduces energy consumption to produce asphalt concrete, lowering costs and greenhouse gas emissions. 2. Reduces off - gassing (smoke) of asphalt concrete by keeping temperature under the boiling point of "light oils" in the liquid asphalt, benefiting construction workers and the public. 3. Because the light oils are not boiled off, the liquid asphalt coating the rock particles is slightly thicker, which slows the aging process of the asphalt. 4. Reduces the oxidation caused during high temperature production that causes premature aging of the asphalt, which should provide a longer life product. The use of warm mix asphalt pavement is required on City of Eugene projects. SRRP MISSION Per Resolution No. 4953, the SRRP "will prepare a report, separate and distinct from the report prepared by the outside auditor, documenting the City's use of the bond proceeds and noting whether the bond proceeds were used in compliance with the terms of this Resolution." 2012 SRRP REPORT
