Aggregates – sand, gravel, crushed stone and quarried rock -- play a vital role as the “building blocks” of the Heavy Construction Industry. They provide the critical skeleton for roadway infrastructure, buildings and other structures.

Tomlinson offers a diverse selection of aggregates from our quarry operations. Among the products we produce are concrete aggregates, clear stones, asphalt aggregates, manufactured sands, railway ballast, armourstone, gabion and rip rap. Determining the suitability of an aggregate for a particular application involves careful consideration of its physical, chemical, mechanical, and mineralogical properties.

Characteristics to be considered when selecting aggregates include:

• Grading
• Durability
• Abrasion and skid resistance
• Resistance to polishing
• Particle shape and surface texture
• Absorption
• Unit weight

Protecting the Environment
R.W. Tomlinson is a leader in developing, utilizing and promoting “green solutions” for the heavy construction industry. In addition to offering a wide array of natural and manufactured aggregates, Tomlinson is committed to the environmental benefits of processing and incorporating inorganic materials — such as crushed glass — from previous construction, demolition and municipal waste. For example, recycled concrete and asphalt products are regularly processed and added to virgin products in proportions as high as 30%.

Tomlinson recognizes that the heavy construction industry relies on the production of quality aggregates for its success. By creating sound “green” solutions for 
the industry Tomlinson is proving that it takes its role 
as steward of the environment seriously.
