What is Aggregate?
Merriam – Webster defines rock aggregate as: Formed by the collection of units or particles into a body, mass, or amount.
COLLECTIVE: composed of mineral crystals of one or more kinds or of mineral rock fragments
Aggregates refer to all types of quarry materials such as sand, gravel and rock. They are used to build and maintain our roads, construct bridges and buildings, provide solid bases for playing fields, water lines and sewer systems. It is the main component in both concrete and asphalt, which all modern heavy construction relies on as their key building ingredients.
When we look at aggregates what we see is just a loose collection of rock, sand and gravel but when those materials are sorted into sizes, rough or smooth edges, and material type they become crucial elements in the things we build. We use these sorted aggregates for play sand, drain rock, road base, pathways, landscaping, septic fields and many other applications in building, mining and manufacturing industries. When they are combined with other substances we can produce asphalt for roads, concrete for all manner of construction, soil blends for grass, sports fields and gardens, patio slabs and pre-fab building panels to name a few.
Believe it or not, without aggregates our lives would be significantly different; no power as the transmission lines would have no support or anchor for the steel towers, no phones as poles and microwave repeaters would have no bases to build them on. Even the homes we live in and the businesses we frequent would be unlike anything we see today. Aggregates are a crucial element to our modern way of life. Fortunately, British Columbia has some of the best and most plentiful aggregates in the world.
