Feasibility of Substituting #78 for #8 Aggregate in S-5 Mixes
Report No: 80-R13
Published in 1979
About the report:
The study investigated the feasibility of using a coarse aggregate in the S-5 asphalt mixes. Virginia Department of Highways and Transportation specifications were adhered to with the exception of incorporating into the mix a small percentage of +1/2" material. A #78 aggregate was selected from three quarries in Virginia and substituted for the #8 aggregate in the S-5 mixes. In the design of the mixes, consideration was given to the gradation of material from each quarry, and tests were performed on the mixes using the Marshall method to determine the density, flow, stability, voids, and asphalt content. The results of tests on the mixes were compared graphically with Department specifications and the acceptability of each mix was determined.
