What percentage of the total mineral aggregate by weight is required for an asphalt mix?

The correct percentage of the total mineral aggregate by weight required for an asphalt mix is in the range of 93-96%. This percentage is crucial because it ensures that the asphalt mixture has sufficient stability, durability, and strength to withstand traffic loads and environmental conditions.

The mineral aggregate serves as the backbone of the asphalt mix, providing necessary properties such as resistance to deformation, wear, and cracking. When the aggregate content is within this range, it achieves an optimal balance between performance and workability. It also contributes to proper bonding with the asphalt binder, which is essential for the overall performance of the pavement.

Using an aggregate percentage lower than this range may lead to insufficient structural integrity, while a higher percentage can make the mix too stiff and difficult to work with, affecting compaction and adhesion. Therefore, maintaining the mineral aggregate content within 93-96% is fundamental in achieving a quality asphalt mix that meets performance specifications.
