Investigation of Bituminous Mixes With Different Types of Aggregates

This book studies the investigation of strength properties of bituminous mixes with different types of aggregates, viz, granite, marble, and locally available stone. The granite and marble aggregates were used in partial replacement of locally available stone aggregates, and laboratory tests were conducted to know various parameters like strength, durability, moisture susceptibility, etc. Marshall test was conducted to evaluate the volumetric parameters, which indicated that the stability value of the mix. Mixes having granite as fine aggregates and fillers show higher stability value, making a stronger mix. When granite is used as fine aggregates, the stability value increased by 18.6 % compared to stone aggregates and 22.4 % compared to marble aggregates. Also, when granite is used as both fine aggregates and filler, the stability value increased by 35.3 % compared to stone aggregates and 38.4 % compared to marble aggregates. The compressive strength for mixes with granite aggregates was found to be maximum in comparision to marble and local aggregate mixes. Hence, marble and granite are justified to be used as a material for road construction.
