What should be assessed when testing volcanic aggregates?

When testing volcanic aggregates, it is crucial to assess their specific performance characteristics. This involves examining properties such as durability, strength, and resistance to various environmental factors, which directly impact the performance of concrete or asphalt mixtures in construction applications. Understanding these characteristics ensures that the aggregates will perform reliably under the stresses they will encounter in service, such as weather conditions and load-bearing demands.

While factors like cost-effectiveness, local availability, and aesthetic appeal might be relevant in broader project planning and material selection, they do not directly address the technical and performance-related aspects of the aggregates themselves. The primary focus should always be on how well the volcanic aggregates will perform in the specific context of their intended use, making the assessment of their performance characteristics paramount.
