  1. Quantifying the Costs and Benefits of Pavement Retexturing as a Pavement Preservation Tool The University of Oklahoma Caleb Riemer, P.E. Doug Gransberg PhD, PE MusharrafZaman, PhD, PE Dominique Pittenger, AC

  2. Project Objective CALCULATED VALUE BASED DECISION PROCESS!! • Leverage Previous National Research • Skid Number vs. Crash Rates • Crash Rates vs. Road Conditions • Long Term Pavement Performance Program • Leverage Previous International Research • Macrotexture vs. Crash Rates • Management of Pavement Macrotexture

  3. Polycon E-Krete O.D.O.T. Single Size Armor Coat O.D.O.T . Single Size Armor Coat w/ Calupave • 23 TEST SECTIONS • ¼ MILE LONG (400 M) • ASPHALT SECTIONS • 12 Surface Treatments • 2 Chemical Treatments • 4 Mechanical Treatments • CONCRETE SECTIONS • 1 Chemical Treatments • 4 Mechanical Treatments Calupave Fog Seal Open Graded Friction Course w/ Fog Seal Open Graded Friction Course 1” Mill and Inlay S4 PG(64-22 OK) Fog Seal JLT Asphalt Penetrating Conditioner JLT Asphalt Planer w/ Asphalt Pen. Conditioner O.D.O.T. 5/8” Armor Coat w/ Fog Seal O.D.O.T. 5/8” Armor Coat O.D.O.T. 3/8” Armor Coat Blastrac Shotblasting Skidabrader Shotblasting w/ Fog Seal Skidabrader Shotblasting NovaChip BlastracShotblasting w/ Nano Lithium Densifier Next Generation Diamond Grinding Microsurface Blastrac Shotblasting Diamond Grinding Skidabrader Shotblasting

  4. Test Section Sponsors • Blastrac, Inc. Edmond, OK • Penhall Diamond Grinding, Anaheim, CA • JLT Corp. Cushing, OK • Ergon Emulsions and Materials, Austin, TX • Skidabrader, Inc. Ruston, LA • Polycon, Madison, MS • Haskell Lemon & Hall Brothers, OKC, OK • Pathway Services, Tulsa, OK • Calumet Lubricants, Shreveport, LA

  5. Testing Protocol • Follow change in macrotexture & skid resistance over time. • Macrotexture tests • ASTM STP 583 Outflow meter • TNZ T/3 Sand circle • TNZ P/17 Performance Spec for chip seal texture • RoboTex (Transtec) • High Speed Truck Mounted Laser (Pathway) • Skid resistance measured by ODOT skid tester • Ribbed tire (40 mph) & Smooth tire (40 mph and 55 mph) • Test conducted monthly for 3 years • Plans to extend period to surface failure, but will reduce frequency to quarterly tests

  6. Macrotexture Testing TNZ T3 Sand Circle Hydrotimer Outflow Meter

  7. Economic Analysis Tracking change in engineering properties must be correlated with an analysis of the cost of supplying those properties Life cycle cost analysis for each tested alternative. Develop life cycle cost model for pavement texture over time. Use of Cost Index Number Theory to quantify “Bang for the Buck”
