Pavement Preservation Journal - Fall 2016 - 33

2013 we expanded our use of RAP into 50 percent of all base pavements. This practice will enable us to recycle these millings into our pavement treatments rather than hauling them to a landfill. * Reutilize existing materials in-place. Of all the pavement treatment types, reconstruction projects impact the environment the most, and are the most costly. Typically, the conventional approach included removing the existing asphalt and the layers of material below the pavement, and replacing them with new materials. The truck trips to haul the material away from the project site (generally to a landfill), and virgin pavement material imported to replace what was removed, results in significant fossil fuels expended and further add to the GHGs in the atmosphere. Significant energy is utilized to transport the material in both directions from the project location, and raw materials from the earth are needed to construct the road. Processes such as cold in-place recycling (CIR) and cold central plant recycling (CCPR) refurbish the existing asphalt in our pavements. Also, treating the soil beneath the pavement by adding cement, lime or asphalt emulsion provides an in-place stabilization, resulting in significant environmental benefits. Processes that reuse what is in place eliminate the energy required to transport old and new material from and to the construction site, as well as greatly reducing GHG emissions. benefits of implementing sustainable pavement treatments compared to "worst first" treatment strategies have been substantial. Energy usage was reduced by 81 percent; greenhouse gas emissions reduced by 85 percent; landfill inputs reduced by 260,000 cubic yards; and almost one million tires were incorporated into our roads. In addition, approximately $30 million was saved within a six-year period, which was reinvested back into the road program. As a public agency, optimizing the use of the taxpayer money is a critical aspect in effective governance. Making decisions that reduce GHG emissions into our environment also now are a key component of our project delivery. DPW's three-pronged approach meets all these objectives. Kelley is assistant deputy director, County of Los Angeles, Department of Public Works An end to 'Worst First' In 2010 Los Angeles County decided to change the way we approached treating our roads. Our "worst first" approach of waiting for the distresses to appear before treating the road was replaced with a three-pronged sustainable approach that focused on environmental sustainability and cost effectiveness. After six years of implementing its three-pronged sustainable pavement program, DPW has successfully addressed environmental and economic challenges.
