What technical requirements define modified bitumen repair for asphalt or bitumen modification?

Modified bitumen repair for asphalt involves specific technical requirements, including the use of polymer-modified bitumen (PMB) to enhance elasticity and durability. The repair process requires proper surface preparation, including cleaning and priming, to ensure adhesion. The application temperature must be monitored, typically between 160-180°C, to achieve optimal bonding. Additionally, the thickness of the modified layer should be consistent, generally ranging from 3 to 5 mm, to ensure effective performance and longevity of the repair.
