Use of RAP Continues to Increase on Colorado Highways A record 134,472 tons of reclaimed asphalt pavement (RAP) was placed on Colorado highways as part of 2011 asphalt paving projects.  71% of allowable RAP was used at an average rate of 17%.  “CDOT supports efforts to increase the use of recycled products and we are pleased to see the numbers continue to increase,” stated Jim Zufall, CDOT Staff Materials Engineer.  The current CDOT specification allows 20% RAP in the top mat and 25% in lower lifts.   (CDOT RAP Specification)  (2011 CDOT RAP Summary Usage)

Changes Proposed to CDOT Compaction Temperature Restrictions  A joint CAPA/CDOT Task Force effort has been working over the winter to consider changes to the Sec. 401.17 Compaction Temperature specification.  The asphalt industry through CAPA has requested a change to allow rolling at lower temperatures.  “Having the flexibility to continue rolling at lower temperatures is beneficial on some mixes and some paving conditions,” stated Tom Clayton, CAPA Director of Training & Member Services. “Achieving the specified density requirement and getting roller marks out should be the primary goal,”  Clayton added.  The proposed specification will allow compaction of unmodified AC mixes below 185°F and the compaction of modified AC mixes below 230°F  provided the Contractor can demonstrate that there is no damage to the finished mat.
