Dolomite has several applications in highway construction, primarily due to its durability and versatility. Here are some of its uses:
Aggregate in Asphalt and Concrete Mixes: Dolomite can be used as an aggregate in the production of asphalt and concrete, providing stability and strength to these materials. This ensures the longevity and durability of the roadway.
Base Material: Crushed dolomite is often used as a base material for roads and highways. It provides a stable foundation, distributes load, and enhances the strength of the road structure.
Drainage Layer: Due to its granular characteristics, dolomite can be used in the construction of drainage layers beneath road surfaces. It facilitates proper water drainage, preventing water accumulation and potential damage to the road.
Road Surface: In some cases, dolomite is used as a road surface material itself, particularly in areas where a more cost-effective solution is necessary.
Stabilization and Fill Material: Dolomite can be used to stabilize soil and as a fill material to provide the necessary support and grading for road construction projects.
Dolomite’s high density, hardness, and resistance to weathering make it a valuable resource in the construction and maintenance of highways.
