SSP Use Guidelines for 19.0 mm WMA High RAP Mixtures for Low Volume Roads

PennDOT has worked with the Pennsylvania Asphalt Pavement Association to develop a standard special provision (SSP) facilitating the use of higher amounts of reclaimed asphalt pavement (RAP) into 19.0 mm asphalt mixtures for use on low volume roadways. The SSP allows up to a maximum of 50% RAP by weight in the mix, however, existing approved mixes with lesser quantities of RAP may also meet the requirements of the SSP. The SSP is available for use immediately on projects. Review the SSP here:
