Several types of fillers, such as crushed fines, portland cement, lime, fly ash, and carbon black, can be added to asphalt concrete. Fillers are used to satisfy gradation requirements of materials passing the 0.075 mm sieve, increase stability, improve bond between aggregates and asphalt, or fill the voids and thus reduce the asphalt required.
