Silica And Road Construction

Concrete and masonry products, the primary materials used in road construction, contain both silica sand and rock containing silica. Why is silica exposure a health concern? The key health concern to breathing silica is an incurable lung disease called silicosis. Lung damage from silicosis is permanent, making prevention extremely important.
