The effects of baghouse fines and mineral fillers on asphalt mix properties in the Eastern Province of Saudi Arabia

Abstract

The objective of this study is to determine the effects of "Baghouse Fines" in the asphalt mixes. The analysis includes carrying out Marshall tests on mixes having various filler/baghouse fines ratios. Other tests to study the effects include stability loss, viscosity, penetration, shear-modulus, and softening point.

The results of the study indicate that indicate that baghouse fines can greatly affect the properties of the mix, such as the optimum asphalt, stability, and stability loss. Asphalt mortars using different filler/baghouse fines rtio exhibited varied viscosity and penetration. Stability loss, which is a main factor in the design of local mixes, was decreased drastically by the inclusion of baghouse fines on asphalt mixes was the percentage of carbons. It is anticipated that the results of this study will be of great help in the improvement of local mix properties.
