Aggregates Aggregates and asphalt are some of the most essential raw materials in the construction industry today. Aggregates in particular have an astounding variety of uses. From the roads we drive on to bridges, bricks, concrete, wallboard and roofing tiles – all utilize aggregates. Every town and city and the roads and highways connecting them were built and are maintained with aggregates. Aggregates are increasingly being used to protect our environment too. Soil erosion-control programs, water purification and the reduction of sulfur dioxide emissions from electric power plants are just a few examples of environmental applications of aggregates. Aggregates are produced by quarrying naturally-occurring rock deposits. In the case of Midsouth Aggregates these are granite and limestone. Rock is extracted by carefully controlled blasting, then crushed and graded to produce stones of different sizes which are used for different types of application. For instance, the type of aggregate used in concrete or asphalt will be a different size to the material used in pipe bedding or erosion control. Asphalt Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement binds the material together. Asphalt is an increasingly sophisticated material. Pavements being built today can be engineered to meet a variety of needs – for less noise, greater durability, enhanced skid resistance, reduced splash and spray in rainy weather, and a smoother ride than ever before.

America’s Number One Recycled Product Asphalt pavement is 100 percent recyclable and reusable and according to a recent report by The Environmental Protection Agency and Federal Highway Administration (FHWA/EPA) asphalt is America’s number one recycled product. When an old asphalt road surface is removed from the road it is reclaimed, crushed and graded to produce Reclaimed Asphalt Pavement (known as “RAP
