What is reason for spreading prime coat over wet mix macadam

The primary reason for spreading a prime coat over wet mix macadam during road construction is to enhance the adhesion between the underlying base layer (wet mix macadam) and the subsequent layers, such as the bituminous surface course. The prime coat acts as a bonding agent, improving the bond strength and promoting a strong and durable road structure.
Here are a few key reasons for applying a prime coat:
Waterproofing: The prime coat helps to waterproof the base layer, preventing the penetration of moisture from the subgrade. This is crucial as excessive moisture can weaken the base layer and compromise the overall stability of the road.
Dust Control: By applying a prime coat, the fine particles and dust present on the surface of the wet mix macadam are effectively bound together. This minimizes the generation of dust during subsequent construction stages and provides a cleaner working environment.
Adhesion Promotion: The prime coat creates a tacky surface on the wet mix macadam, ensuring better adhesion between the base layer and the subsequent layers, such as the asphalt or bituminous surface course. This improves the overall structural integrity of the road and helps to prevent delamination.
Surface Stabilization: The prime coat helps to stabilize the surface of the wet mix macadam, reducing the movement of aggregates and preventing their displacement during subsequent construction activities. This results in a more stable and compact base layer.
Overall, the application of a prime coat is essential for ensuring the long-term performance and durability of the road by improving adhesion, waterproofing, dust control, and surface stabilization.
