Abstract

"The objective of this investigation was to determine the effects of deviations from the recommended gradation of aggregate upon asphalt concrete mixes. The aggregate used in this study was a good grade Missouri Limestone and was mixed with an asphalt cement of 85-100 penetration grade. A control mix was designed in accordance with the Marshall Method using a gradation recommended by the Asphalt Institute. Ten aggregate blends were prepared by wasting certain fractions or combinations of fractions and the wasted weights were redistributed into the coarser or finer aggregate sizes. The test mixes were designed using the same method and procedure as the control mix. The effects of using gap graded aggregate on the unit weight, stability, voids in the mineral aggregate, air voids and flow, of the bituminous mixes were studied. It was found that some of the mixes could be used satisfactorily without modification depending upon the size and location of the wasted fraction"--Abstract, page ii.
