Results showed that the optimal mix was the mix that had basalt coarse aggregate and limestone fine aggregate. In order to overcome the stripping potential of the optimal mix, 20% of the filler portion of the aggregate, material smaller than 0.075 mm, was replaced by lime. The optimal mix showed superiority, over the tested mixes, in all the ...

اقرأ أكثرFor asphalt concrete mixes, hard aggregates, such as basalt, are desirable because they tend to contain elongated particles which increase the fine aggregate angularity (FAA) and the mix voids in mineral aggregate (VMA). One hundred percent crushed and cubical limestone sands produce FAA values in the low forties.
