Evaluation of rutting resistance of coarse graded aggregate asphaltic concrete mixes in Clark County, Nevada

The purpose of this study is to evaluate the effectiveness of utilizing coarse aggregates in asphaltic concrete pavements for reducing rutting in Clark County, Nevada. Previous specifications used for asphaltic concrete mix designs in the Clark County area allowed for a wide range of aggregate gradations. The aggregate gradations in the asphaltic concrete mixes produced from these specifications tended to be on the finer side of the range. The pavements constructed based on the specifications were observed to be tender and susceptible to rutting. Paving projects were initiated which demonstrated that coarser aggregates in the asphalt mixes appeared to reduce rutting. This study will (1) present case studies where fine and coarse aggregate asphaltic concrete mixes were used in the pavement; (2) perform a comparative evaluation of these case studies and; (3) recommend an aggregate gradation for adoption in the Uniform Standard Specifications for Public Works' Construction Off-Site Improvements, Clark County Area, Nevada.
