Chapter 4 - Construction of Performance Graded 82-22 Polymer <strong>Modified</strong> HotMix AsphaltOnce MDOT granted approval to the contractor’s proposed mix design (see AppendixH) for the PG 82-22 HMA, a 450’x 24’ test strip was constructed on June 12, 2001 toestablish rolling patterns and density gauge biases. The paving train consisted of aCraftco Accupave Windrow propelled by a Cat 966C, a Lincoln Shuttle Buggy, aBlaw Knox paver and 2 Cat CB634C 15 ton steel wheel rollers.The liquid AC used in the hot-mix was modified with a Styrene Butydene Styrene(SBS) polymer to achieve the PG 82-22 grade and was supplied by Ergon Asphalt &Emulsions, Inc., Memphis, Tennessee terminal. It should also be noted, that MDOTstandard practice is to include 1% hydrated lime in all our asphalt mixes to serve asan anti-strip agent. The PG 82-22 mix involved in our research did not deviate fromthat policy.For construction of the test strip, hot-mix asphalt left the plant at approximately 345degrees F. Temperatures behind the paver averaged 340 degrees F. A rolling patternwas established using six passes with a 15 ton roller in vibratory mode and onefinishing pass in static mode. Attached in Appendix H is a complete listing of alldensities both gauge and core verified gradations, SGC air voids and AC contents.Three gyratory pills were compacted to approximately 7 % air voids using mixmaterial and run in the department’s Asphalt <strong>Pavement</strong> Analyzer (APA) dry andsubjected to 8000 cycles of 100 psi hose pressure at 147 degrees F. The pills averagedepth of rut following the test was 0.10 inches (2.55 mm). The complete results ofthe APA testing can be found in Appendix H.Our Research section would consist of 2 – 2” thick lifts of 12.5mm NominalMaximum Aggregate Size (NMAS) PG 82-22 hot mix asphalt. A chert gravel &limestone blend was utilized for the mix. MDOT policy currently prohibits the use ofmore than 30% limestone in surface course asphalt mixes due to concerns aboutpolishing of some limestone mixes and the subsequent lack of friction resulting fromthat polishing. This mix adhered to that limitation and utilized only 30% limestoneaggregate. The test strip would serve as the lower lift of our research section locatedon U.S. 72 Westbound at the intersection on Cass Street.On June 15, 2001 the surface lift of the left thru lane of our 450’ research section waspaved. Temperatures of the mat directly behind the paver averaged approximately305 degrees F. See Appendix H for the surface mat temperatures. Attached inAppendix H is a complete listing of all densities both gauge and core verified,gradations, SGC air voids and AC contents from the surface of the left thru lane ofthe research section.On June 18, 2001 the surface lift of the right thru lane of our 450’ research sectionwas paved. Temperatures of the mat directly behind the paver averagedapproximately 305 degrees F. See Appendix H for the surface mat temperatures.27
