  1. 2012 NCAT Pavement Test Track • Experiment Design and Construction Update

  2. Accelerated Pavement Damage 2

  3. Foamed WMA Rutting Performance 3rd Summer 2nd Summer 1st Summer 3

  4. High RAP Reflective Cracking 4

  5. 2012 Track Research Cycle • Traditional stand alones • Traffic continuation • Mill/Inlay • Structural Sections • Green Group (GG) • Preservation Group (PG) • Safety Edge implementation (FHWA) 5

  7. 2012 Sponsor Projection6/18/2012

  8. Cold Central Plant Recycling (CCPR) • 3 of 5 Track sections sponsored by VDOT • 5” foamed recycle on top of 6” base vs 8” FDR • Virginia RAP run through central mix plant • 2” versus 4” new plant mix overlay on base • 4” new plant mix overlay on 8” FDR • Desire to include recycle in PG study 8

  9. 2012 Preservation Group (PG) Study • Quantify life cycle benefit of study treatments • Time/traffic to return to pretreatment condition(s) • Life extension effect on underlying pavement • Sampling/testing for construction quality 9

  10. 2012 Preservation Group (PG) Study • Traffic continuation on 2009 GE+ test sections • Stop traffic when “trigger” distress(es) reached • Trigger may be cracking or roughness increase • Apply consensus treatments to GE+ sections • Duplicate / expand study in off-Track research 10
