Summary:
Reports on the three year performance of two test projects constructed with 0, 1, 2, and 3% CRM in the hot mix using the
dry process and a PlusRide section.  Rutting, cracking and raveling were recorded semi-annually.  The mixes were
tested for density, Marshall properties and resilient modulus.  Surface friction was measured annually.  Snowplow
operators were surveyed to determine if there was any difference in show and ice removal for the different test sections.
