Answer :
Granular sublayers thickness should be within c. 50 mm and 150 mm.
Granular sublayers, which are necessary in civil engineering for road and pavement construction, must comply to precise thickness criteria to maintain structural integrity. These layers typically range in thickness from 50 mm to 150 mm, meeting industry standards to ensure stability and optimal load distribution.
This thickness range accounts for changes in project needs, soil conditions, and projected traffic loads, allowing engineers to customize designs for durability and performance.
Granular sublayers provide strong support by keeping a sufficient thickness, reducing the possibility of settlement, rutting, and other forms of distress under dynamic traffic loads. Thus, adhering to these criteria is crucial for long-term and safe infrastructure.
