Cold In-place Recycling Project
Posted Sep 2009
The City of Moreno Valley engineering staff was introduced to the Cold In-place
Recycling (CIR) process 2 years ago, resulting in this project of 58,850 square
yards. Recycling was expected to reduce the project duration by 5 working days at
a cost reduction to the City over $262,000. PRS estimated 7 working days on the
$475K contract with Hardy & Harper, but completed the job in 5 days.
Pavement Recycling Systems hosted 42 guests from 13 agencies & consultants on
July 23rd in Moreno Valley. Two are currently planning future CIR projects. Observing
agencies included:
Modesto Mall Repaved using Cold Recycled Asphalt
Posted on Jul 06 2009 at 12:12 PM
Beginning in early September 2008, the Vintage Faire Mall in Modesto is being repaved.
Don Mangan with Pave West, the paving contractor was looking for solutions that
would save the Mall owner money without sacrificing quality. Having used cold recycled
material before, Don knew it was a good solution and viable alternative to the more
expensive "remove and replace" standard practice.
Don decided to hire Pavement Recycling Systems and met with the mall owner to lay
out his strategy. Agreement was quickly made and work started the week of September
15th. First PRS milled off most of the existing asphalt, leaving only a thin skin
behind or exposing the underlying base section.
American Asphalt & Concrete Paves

Reclaimed Aggregates Inc. (RAI) has, for many years been constructing Cold Central
Plant Recycling (CCPR) projects for various public and private pavement owners.
CCPR is a specialized and urban-friendly technology that can be used anywhere as
an alternative to conventional paving methods in parking lots, streets, alley ways,
frontage roads, cul-de-sacs, and storage yards.
In April 2009, Tony Barker, senior estimator with American Asphalt & Concrete
located in Spring Valley, California, contacted RAI regarding preparing a "value
engineering" proposal for an up coming project. RAI proposed using a 100% recycled
Renew™ asphalt as opposed to using conventional hot mix asphalt repaving method
originally specified for the project.

Often a new roadway construction technology is not readily accepted by a contacting
agency due a perceived failures with the first few projects constructed. These "failures"
are often a result of the agency's lack of experience and poorly defined expectations
among the parties involved as opposed to problems with the technology itself. In
an attempt to successfully implement new pavement strategies and develop consistent
expectations, Caltrans developed a pilot project process through the Pavement Preservation
Task Group (PPTG). This pilot project process is intended to prevent hasty conclusions
and provide all "new" technologies an opportunity to succeed.
