Dense grade, also known as dense graded aggregate or well-graded aggregate, is a type of construction material that is made up of a mixture of coarse and fine particles. It is typically used as a base material in construction projects, such as roadways, foundations, and buildings.
Dense grade is characterized by its high compaction strength and low air voids. It is made by mixing together various sizes of aggregate, including crushed stone, gravel, and sand, and then compacting the mixture until it becomes dense and sturdy. The particles in dense grade are tightly packed together, making it a strong and stable base material.
Dense grade is commonly used as a base for roads, driveways, and other types of paved surfaces. It is also used as a base for foundations, retaining walls, and other structures. In addition to its strength and stability, dense grade is also known for its durability and ability to withstand heavy loads.
Overall, dense grade is a versatile and essential construction material that is used in a variety of applications.
