  1. Example 3: Determination of Mr = 3/8

  2. Example 4: Pavement Thickness Given 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)

  3. Calculate the minimum HMA thickness = 3 inch Calculate the thickness of emulsified asphalt base = 10.5 -3 = 7.5 inch Cont. Example 4: Pavement Thickness 3 in Surface base 7.5 in Subgrade Minimum Thickness of Asphalt Concrete Over Emulsified Asphalt Bases

  4. Considered as a cold mix asphalt = Fine aggregate + Emulsion

  5. Marshall Method- Numerical Example
