• Abstract:
  The Indiana’s SPS9-A site was initiated as a part of the ; SHRP’s LTPP program in 1997 to study the influence ; of binder grades on mixture performance. In the earlier ; phase of this study entitled Development of Indiana’s ; SPS9-A Site, five Superpave sections with different ; binder grades (including one SBS-modified binder) and ; one Marshall section were constructed on a 2.5-km ; section along eastbound I-70 east of Indianapolis. Four ; of the five Superpave mixes had the same aggregate ; gradation, source and mix design. The remaining fifth ; section contained 15% RAP and the same binder grade ; as the control Superpave section. In an earlier study, ; lab-compacted specimens from plant-produced mixtures ; obtained at the time of construction were tested to evaluate ; rutting and thermal cracking performance. Binders ; recovered from field core samples at predetermined ; intervals were tested. These results were compared with ; findings from field distress surveys conducted within the ; initial four-year study period. Discrepancies between the ; observed pavement distress (cracking and rutting) and ; mixture testing resulted in the initiation of the current ; study, with a view to obtain two more sets of field core ; samples for additional testing on recovered binders and ; for assessing the cracking resistance of the mixtures by ; directly testing the core samples at low temperatures. ; The overall objective of this research project was to provide ; long-term performance data of mixes with the same ; job-mix formula (JMF) and gradation but with different ; binder grades. It was also to allow evaluation of the longterm ; performance of RAP.
