Abstract

"The objective of this investigation was to determine if naturally occurring gap-graded gravel can produce asphaltic mixtures meeting minimum requirements for satisfactory pavement behavior.

Ten gap-graded mixes were blended by eliminating certain intermediate sized fractions or combination of fractions from the gradation of a control mix. The weight of the fractions eliminated was distributed to either the coarser or finer aggregate fractions.

All specimens were prepared and tested in strict accordance with procedures set forth in ASTM Designation D1559, "Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus."

The physical properties compared and analyzed were (1) unit weight, (2) stability, (3) flow, (4) percent air, (5) percent voids filled with bitumen, and (6) voids in the mineral aggregate. Test results reveal that some of the mixtures can meet minimum criteria for a satisfactory mix with the principle problem being one of deficient air-voids relationships "--Abstract, page ii.
