Abstract

"The purpose of this investigation was to ascertain the feasibility of interpolating values of the physical properties of a dense graded bituminous mix between known values. Also the effects of limestone mineral filler on the properties of a dense graded mix are evaluated. The variables in this study were mineral filler and asphalt cement. Control mixes were established at 2, 6 and 10 percent mineral filler and experimental mixes were prepared at 4 and 8 percent filler. The aggregate consisted of limestone and was mixed with an asphalt cement of 85-100 grade penetration. Al mixes were tested by the Marshall Method. The physical properties analyzed were stability, flow, unit weight, air voids and voids in the mineral aggregate. It was determined that interpolation between known values of the physical properties of a dense graded mix is valid for a specific range of asphalt contents and that asphalt content was critical at low (3-4 percent) and high (7-8 percent) ranges. Mineral filler increased the desirable properties of a bituminous mix up to a certain asphalt content and then the desirable properties diminished rapidly"--Abstract, page ii.
