How does texture in aggregates influence performance?

Texture in aggregates plays a significant role in performance, particularly in how the aggregates interact with one another and with binding materials. The texture of an aggregate refers to the surface characteristics and physical shape, which can include factors like roughness, angularity, and the presence of fines.

When aggregates have a rough texture and are more angular, they generally provide better interlock and increased friction when compacted. This enhances the friction angle, which is crucial for ensuring stability and strength in applications such as pavement and base layers. A higher friction angle means that the aggregate will resist sliding and shifting under load more effectively, contributing to the stability of the entire structure.

Moreover, the bonding capacity of the aggregates is heavily influenced by their texture. A rough, textured surface allows for better adherence between the aggregate particles themselves and between the aggregates and any applied binders or stabilizers. Enhanced bonding leads to improved overall strength and longevity of the material under stress.

In contrast, the other choices provided do not accurately reflect the importance of texture in aggregate performance. For example, while the color of the aggregate or its weight might have some relevance in certain contexts, they do not directly impact the inherent frictional properties and bonding capabilities that texture does.
