The choice between 1-1/4" crushed unwashed rock and other aggregates depends on the specific requirements of the project, such as cost, stability, drainage, and load-bearing capacity. There are several advantages of 1-1/4" Crushed Unwashed Rock in construction projects:
Cost-Effective: Since it doesn't require washing, it is often less expensive than washed aggregates, making it a budget-friendly option for large-scale projects.
Enhanced Binding: The natural dust and fines present in unwashed rock can improve binding properties, helping the aggregate to compact more effectively and create a stable base.
Good Interlocking: The coarse and irregular texture of the crushed rock provides excellent interlocking properties, which enhances the stability and load-bearing capacity of the foundation.
Versatility: It can be used in a variety of applications, including road bases, driveways, building foundations, and landscaping projects, making it a versatile choice for different construction needs.
Erosion Control: Its stability and resistance to water flow make it effective for controlling erosion in areas prone to runoff.
Durability: The robust nature of the crushed rock ensures long-lasting performance, even under heavy loads and harsh conditions.
 
These advantages make 1-1/4" crushed unwashed rock a valuable material for many construction projects.
