What is the extended width for the application of prime coat on each side of the road?

Explanation:
The extended width for the application of a prime coat on each side of the road is 300mm. This measurement is important as it allows for adequate coverage of the substrate, ensuring proper bonding between the underlying material and the asphalt. A prime coat enhances the adhesion of the subsequent layers and mitigates the risk of moisture infiltration, which can compromise road durability. The specified width helps in achieving an even application, reduces the likelihood of weak points at the edges, and contributes to the overall integrity of the pavement structure.
