Bitumen is used in road construction due to various properties and advantages. The bitumen as a raw material in flexible road construction and bitumen as a mix (composing other materials i.e. aggregates etc.) serves certain advantages, that prompt to use bitumen widely in road construction.
Aggregates are inert granular ingredients, such as sand, gravel, or crushed stone, which, along with water and Portland cement, are an important component in concrete. Which is classified into two distinct categories, Fine and Coarse.
Fine aggregates normally consist of natural sand or crushed stone with most participles passing through a 3/8inch sieve.
Coarse aggregates are any particles larger than 0.19 inches but usually range between 3/8 and 1.5 inches in diameter.
Aggregates must be pure, hard, and strong particles that are free of absorbed contaminants, clay coatings, and other fine materials that could cause concrete to deteriorate.
Laira Group will deliver high-quality aggregate in a range of sizes to our valued clients, based on their needs.
