VDOT has limited experience with rubber modified asphalt mixtures in general and even less experience with GTR content that exceeds 10%. The purpose of this study was to establish a performance baseline for an asphalt rubber gap-graded mixture (AR-GGM 12.5) using the wet process on I-85 in the Richmond District (I-85 Southbound, Dinwiddie County). Another objective was to compare its performance with VDOT’s stone matrix asphalt (SMA) mixture, which is also a gap-graded mixture. This study found that AR-GGM mixtures can be placed with no special field accommodations (compared with SMA mixtures), and the special provision developed for AR-GGM mixtures is effective. Further, based on laboratory performance testing, both the AR-GGM and SMA control mixtures tested in this demonstration project were crack and rutting resistant, with the AR-GGM mixture exhibiting more flexibility (i.e., lower stiffness). Both sections are performing as expected after 3 years of traffic and exhibiting minor to no distresses, with a Critical Condition Index greater than 90. However, at this early stage of field service, it is too soon to quantify a performance advantage of AR-GGM mixtures in comparison with conventional SMA mixtures. This study recommends continued use of AR-GGM mixtures for suitable projects as a reflective cracking mitigation tool. Further, the study recommends continued performance monitoring of the study sections to evaluate the cost-effectiveness of AR-GGM mixtures in comparison with SMA mixtures.]]> Tue, 06 Sep 2022 16:02:22 GMT https://trid.trb.org/View/2014779 A Novel Design Toolkit to Assess Asphalt-Rubber Gap-Graded Mixture Performance: Target Properties and Parametric Relationships https://trid.trb.org/View/1628408 Wed, 21 Aug 2019 09:35:46 GMT https://trid.trb.org/View/1628408 Investigation of Cracking Performance of Asphalt-Rubber Gap-Graded Mixtures: Statistical Overview on Materials’ Interface https://trid.trb.org/View/1631543 Fri, 16 Aug 2019 15:51:26 GMT https://trid.trb.org/View/1631543 Comprehensive Laboratory Testing and Evaluation of the Evaporative Cooling Effect of Pavement Materials https://trid.trb.org/View/1571578 Fri, 25 Jan 2019 10:31:45 GMT https://trid.trb.org/View/1571578 Asphalt-rubber gap-graded mixture design practices: a state-of-the-art research review and future perspective https://trid.trb.org/View/1460837 Thu, 25 May 2017 13:56:01 GMT https://trid.trb.org/View/1460837 Design and Construction of a Full-Scale Test Section with Asphalt Rubber Gap-Graded Wearing Course Mixture https://trid.trb.org/View/1253911 Wed, 03 Jul 2013 11:22:24 GMT https://trid.trb.org/View/1253911 Durability Assessment of Asphalt Rubber Mixtures https://trid.trb.org/View/1141965 Wed, 18 Jul 2012 16:11:30 GMT https://trid.trb.org/View/1141965 Laboratory Evaluation of Performances of Asphalt Rubber and Gap Graded Mixtures https://trid.trb.org/View/921505 Fri, 16 Jul 2010 11:36:13 GMT https://trid.trb.org/View/921505 Evaluation of Interlayer Shear Bond Devices for Asphalt Pavements https://trid.trb.org/View/913243 Wed, 24 Feb 2010 14:57:50 GMT https://trid.trb.org/View/913243 Characterizing Enhanced Porosity Concrete Using Electrical Impedance to Predict Acoustic and Hydraulic Performance https://trid.trb.org/View/798799 Thu, 01 Mar 2007 08:37:07 GMT https://trid.trb.org/View/798799 EVALUATING THE USE OF LOWER VMA REQUIREMENTS FOR SUPERPAVE MIXTURES https://trid.trb.org/View/745837 Wed, 12 Jan 2005 00:00:00 GMT https://trid.trb.org/View/745837 NOVACHIP (REGISTERED TRADEMARK) https://trid.trb.org/View/660879 Fri, 12 Sep 2003 00:00:00 GMT https://trid.trb.org/View/660879 UNSIGNALIZED INTERSECTIONS - A THIRD METHOD FOR ANALYSIS https://trid.trb.org/View/723100 Fri, 02 Aug 2002 00:00:00 GMT https://trid.trb.org/View/723100 ULTRATHIN https://trid.trb.org/View/716612 Tue, 05 Feb 2002 00:00:00 GMT https://trid.trb.org/View/716612
