Example 3: Determination of Mr
= 3/8
Example 4: Pavement ThicknessGiven Mr = 10,000 psi (69 MPa) and ESAL = 106, design the thickness of a pavement with a HMA surface over a type-II emulsifies asphalt base
Combined thickness = 10.5 inch (267 mm)Combined thickness = 10.5 inch (267 mm)
Cont. Example 4: Pavement ThicknessCalculate the minimum HMA thickness = 3 inchCalculate the thickness of emulsified asphalt base = 10.5 -3 = 7.5 inch
