👉 The Blvd fluid, also known as Bitumen Fluid or Bitumen Base Fluid, is a thick, black asphalt-based product used primarily in road construction and maintenance. It's a key component in the creation of flexible pavements, providing essential durability, waterproofing, and resistance to deformation. Blvd fluid is pumped onto prepared road surfaces during construction or rehabilitation, where it hardens over time to form a stable, long-lasting surface layer. Its high viscosity allows it to fill road irregularities and create a smooth, even finish, while its adhesive properties bind aggregate particles together, enhancing the pavement's structural integrity and lifespan.
