Abstract

Many road networks are using hot mix asphalt (HMA) to construct pavement layers. The Marshall method is the common procedure used in the design of the HMA and used at the time of the construction of the roadway to quality control. The present work is using ceramic fiber as a reinforcement to improve the characteristics of the HMA. The Marshall properties are examined by several tests such as Marshall stability test, and the flow test. The group of samples was made by utilizing 0.50, 1.0, 1.5, and 2.0 percentages of ceramic fibers by the total weight of the mixture. The results of the experiment showed the maximum Marshall stability occurred at a value of 1% ceramic fiber; the flow value decreased with increasing of fiber content, and the maximum Marshall quotient occurred at a value of 1% ceramic fiber. Also, the air voids, void filled with asphalt, and the void in mineral aggregate increased with increasing ceramic fiber content.
