A project to resurface nearly five miles of Orange Grove Boulevard in Pasadena was completed late last year on time and within budget, according to the director of the city Public Works Department.
The work to resurface the busy roadway between Lincoln Avenue and Sierra Madre Villa Avenue was completed by contractor American Asphalt in December, according to a report submitted Thursday by Pasadena Director of Public Works Ara Maloyan.
“The uniqueness of this project was being able to incorporate several environmentally sustainable elements, one of which was completely new to the City of Pasadena: the Cold-in Place Asphalt Recycling method,” Maloyan wrote.
Through this process, crews are able to recycle the top 3 to 4 inches of existing roadway “in place” by grinding it up and mixing it with an asphalt emulsifier and a “rejuvenator material,” Maloyan explained.
Once cured, sustainable Asphalt Rubber Hot Mix, or ARHM, is laid on top, he added. ARHM is manufactured from trashed car and truck tires, both diverting nearly 27,000 tires from landfills and increasing road durability and decreasing road noise.
“Using Cold-in-Place recycling on this project is estimated to have eliminated 370 truck trips compared to standard removal and reconstruction,” the report stated.
While in the process of resurfacing, Public Works also upgraded 101 curb access ramps, installed concrete gutters and replaced road marking with “brighter, more durable ‘thermoplastic pavement markings,’” according to the report.
