Field Performance of Maintenance Treatments Constructed with Reclaimed Asphalt Pavement (RAP) (187-24)

In this study, RAP was blended with recycling emulsions and conventional maintenance mixtures in attempts to improve its field performance as a maintenance mixture. RAP was also mixed with stabilizers and used as a base material in maintenance projects. Several field experiments were constructed throughout the state, and this report documents their performance.|In general, most of the field experiments performed well and much better than district personnel anticipated at the onset of the study. It was determined that RAP could be used successfully as a maintenance mix for routine maintenance treatments by cold-mixing the RAP with recycling agents or by blending the RAP with conventional, stockpiled maintenance mixtures. RAP was also used successfully as a stabilized base material on maintenance projects.|Results of this study were used to develop "Guidelines on the Use of RAP in Routine Maintenance Activities" as referenced in this report.
