Evaluation of Coarse-Graded Superpave HMA Pavements in North Dakota Using the Asphalt Pavement Analyzer

The aggregate gradation used in Superpave hot mix asphalt (HMA) mix design is required to be within control points at 0.075 mm (No. 200), 2.36 mm (No. 8), and nominal maximum aggregate size. Both coarse- and fine-graded mixtures can be designed within these control points. Asphalt-aggregate mixture sensitivity has long been recognized for its potential negative impact on performance if mixture variables, such as the asphalt content (AC) and the fine material content (the percent that passes the #200 sieve) are not carefully controlled during the production of hot-mix asphalt concrete (HMAC). The main objectives of this proposed study are to: (1) Evaluate the rutting resistance performance of coarse-graded Superpave HMA pavement cores using the asphalt pavement analyzer; (2) Carry out permeability tests on coarse-graded field specimen cores obtained from different locations on US Highway 81 north of Grafton, ND: and (3) Identify the in-place air void percentage of coarse-graded Superpave HMA pavement from Highway 81 north of Grafton, ND.
