Figure 6.
The image presents a flowchart outlining the process of determining optimal binder and fibre content in Stone Mastic Asphalt, S M A, aggregate mixture gradation. The flow begins with S M A aggregate mixture gradation, leading to the Marshall test. There are two pathways, one for S M A without fibres, which presents three values, 5.9, 6.2, and 6.5, and a second path for S M A with fibres, branching into the same three values but further detailing binder and fibre content percentages. The flowchart concludes with a focus on finding optimal binder and fibre content, leading to Duriez - G S C - Rutting wheel. Arrows indicate the flow and relationships between elements clearly, with values enclosed in boxes representing a structured decision-making process.Experimental programme flowchart
