Project Description

As an environmental steward, the City of Pasadena is aware of the need to Design and Construct Public Works projects with an environmentally responsible approach. Although, it is a challenge for Public Agencies to keep up with the demand for preservation to our roads, the City of Pasadena is constantly looking to implement more efficient ways to stretch the dollars. The City is looking to perform the right treatment at the right time, incorporate preventative maintenance treatments to preserve good pavement conditions, as well as implementing the use of creative pavement preservation applications, including the use of recycled materials in the treatment selections; and reutilization of the existing materials in-place. The Orange Grove Resurfacing Project showcases the benefits of properly applying the sustainable approach. The City of Pasadena performed a Cold In Place Recycling (CIR) treatment on Orange Grove Boulevard, from Lincoln Ave. to Lake Ave. This segment is one of the major Boulevards that takes motorists East to West through the city, and vice versa. Although there is a small commercial district between Lincoln and Los Robles Avenues, this section of the street is overwhelmingly residential. The pavement on this section was in very poor condition and exhibited severe structural deficiency, therefore requiring major rehabilitation. The objective of the project was to rehabilitate this segment and bring the roadway to current standards to extend the life cycle, and at the same time spending the least amount of funds possible. Construction involved rehabilitating the roadway by recycling the existing pavement to a depth of 3 inches (CIR) treatment then constructing 1-4/5 inches of asphalt rubber hot mix over the CIR pavement. CIR was selected as it reduced time, cost, and incurred minimal public impact. By reusing the existing pavement in-place, the CIR treatment eliminated the need to haul out existing pavement from the project location then importing conventional hot mix asphalt. Eliminating these steps from the project resulted in less environmental impacts by reducing truck trips, shortening construction durations, and reducing road closures. This project reused the existing asphalt material and reduced the Green House Gas by eliminating approximately 370 Trucks being on the road. Moreover, the impact to residents, and business was minimal for the section of road that was re-constructed. The project used funds from SB-1, Federal STPL funds, and Cal Recycle funds. Pavement Recycling Systems, Inc., along with All American Asphalt, performed the CIR treatment of the approximate 1.3 miles long stretch. For the remaining 3.0 miles, an asphalt rubber hot mix overlay was performed, using California recycled crumb rubber, deflecting over 47,000 tires from going to a land fill. When compared to a conventional hot mix alternative, the CIR treatment resulted in a cost savings of approximately $100,000 while extending the service life.
