TRB’s National Cooperative Highway Research Program (NCHRP) Report 598: Performance-Related Tests of Recycled Aggregates for Use in Unbound Pavement Layers explores performance-related procedures to test and select recycled hot-mix asphalt and portland cement concrete materials for use in unbound layers of highway pavements. Appendixes A through C of NCHRP Report 598, which cover the literature review and background information, new aggregate tests, and surface dielectric measurements, were published as NCHRP Web-Only Document 119 at http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_w119.pdf (Author/publisher) This report may be accessed by Internet users at http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_598.pdf
