摘要：	This research effort started in mid 1990's to evaluate the performance of superpave mixtures under Nevada's conditions and to assess the possibility of implementing the Superpave mix design procedure. Field test sections were constructed to compare the performance of Superpave mixtures with the performance of Hveem under the same traffic and environmental conditions. Based on the field performance of several Superpave mixtures throughout the state of Nevada during the late 1990's, NDOT decided to modify the Superpave volumetric mix design method and construct two test sections side-by- side with the conventional NDOT Hveem mixtures on three projects. This report summarizes the laboratory evaluation of the mixtures from the two sections on each of thee projects and that field performance of the sections. The laboratory evaluations assessed the resistance of thee mixtures to the failure modes of rutting, thermal cracking, fatigue, and moisture damage. The field performance included the measurement of rutting data on the field sections.
