Potential Use and Applications for Reclaimed Millings
Purpose: Identify and document economically viable uses for milled asphalt material.
Construction - Project No: WO 4
PennDOT District 1 has been extracting a portion of milled asphalt material from paving operations to produce an asphalt coated chipping stone, but this leaves 50-60% of the material as a byproduct. This remaining material may have a range of potential uses. This project will investigate the most economically useful ways to return the largest benefit from this material for maintenance applications.
In support of PennDOT's Strategic Goals:
Leverage resources to maximize effectiveness and efficiency
Promote continuous improvement and innovation
Once PennDOT District 1 has received the information on ways to beneficially use this material, some or all of the options will be tested and evaluated in a field application. Those that provide the greatest utility and cost savings will be implemented in District 1 counties. When the benefits of these practices have been proven, this information will be shared with other districts.
