Laboratory investigation on volume proportioning scheme of mineral fillers in asphalt mixture
Highlights Five types of fillers in asphalt mix are studied. These fillers are brick dust, fly ash, lime, recycled concrete aggregate and stone dust. For adding filler to the mix, volumetric proportioning scheme is adopted. Seven tests are conducted on fillers and three tests are conducted on asphalt mix. Correspondence between the test results are studied.
Abstract A number of industrial and domestic wastes are being used as replacement of conventional fillers in asphalt mix. Since different fillers have different densities, conventional weight proportioning may give rise to excess or inadequate quantity of filler in the mix. Hence, volume proportioning for fillers is suggested in the present work. Fillers made up of brick dust, fly-ash, lime dust, recycled concrete waste aggregates dust and conventional stone dusts are studied. The fillers are characterized through uncompacted bulk density, particle size distribution, methylene blue, Blaine’s air permeability, scanning electron microscopy, X-ray diffraction and loss on ignition tests. Creep, indirect tensile strength and moisture sensitivity tests are performed on the asphalt mixes and the results are compared.
