When DOT 89 is utilized as an aggregate material for construction projects and paving, it functions as a specialized type of roadbase engineered to meet specific standards set by the Department of Transportation (DOT). Here are four common uses for DOT 89:
Commonly used in road construction projects as a base material for highways, streets, and other transportation infrastructure. Its precise gradation and durability make it suitable for creating a stable foundation that can withstand heavy traffic loads and adverse weather conditions.
DOT 89 is often used in pavement rehabilitation projects to strengthen and stabilize existing road surfaces. It can be incorporated into pavement overlays or reconstruction projects to improve the structural integrity and performance of aging pavements, extending their service life and reducing maintenance needs.
Normally employed for subgrade stabilization to enhance the load-bearing capacity and resilience of the underlying soil. By incorporating DOT 89 into the subgrade layer, engineers can mitigate the effects of soil settlement, moisture fluctuations, and other factors that may compromise the integrity of the roadbase and pavement layers..
This mateial helps prevent erosion along road shoulders, embankments, and drainage channels by providing a stable and erosion-resistant surface. Its compacted form helps maintain soil stability and prevent sediment runoff, protecting adjacent areas from erosion and maintaining the integrity of the roadway infrastructure.
