The failure criteria recommended by the AustRoads Pavement Design Guide is given by the following formula and the values of the fatigue constants for a range of candidate pavement materials are given in Table Q2A below:

\[ N = \frac{K}{(\mu \epsilon)^b} \]

Where:
- \( N \) = Allowable Number of Load Repetitions to Failure
- \( K \) = Fatigue Constant
- \( b \) = Exponent
- \( \mu \epsilon \) = Induced Strain (microstrain)

### Pavement Layer Modulus (MPa) Constants

| Pavement Layer | Modulus (MPa) | Constant \( K \) | Exponent \( b \) |
|----------------------|---------------|------------------|------------------|
| Asphalt | 4000 | 3400 | 5 |
| Cemented Material | 3600 | 350 | 12 |
| Subgrade | 40 | 8511 | 7.14 |

**Table Q2A Damage Criterion**

The associated relationships for design traffic have been supplied as follows:
\[ NSA = 1.1 \times NE \]
\[ NSC = 10 \times NE \]
\[ NSS = 1.1 \times NE \]

Where:
- \( NE \) = Design Traffic Loading (ESAs)
- \( NSA \) = Standard axles with equivalent damage in asphalt (SAs)
- \( NSC \) = Standard axles with equivalent damage in cemented materials (SAs)
- \( NSS \) = Standard axles with equivalent damage in subgrade (SAs)

Calculated strains for a range of cemented subbase thicknesses have been completed using CIRCLY as summarized in Table Q2B for a pavement having an asphalt surface 225 mm thick.

### Computed Maximum Strains (με)

| Pavement Layer | Cemented Subbase Thickness | 150 mm | 175 mm | 200 mm | 225 mm |
|---------------------|----------------------------|--------|--------|--------|--------|
| Asphalt | | 27 | 22.9 | 20 | 17.9 |
| Cemented Subbase | | 74.7 | 66.9 | 60 | 54.1 |
| Subgrade | | 198.9 | 178.1 | 160.3 | 144.9 |

**Table Q2B Computed Maximum Strains (με)**

Based on the information supplied, showing all calculations and any assumptions, determine the required pavement composition for a Design Traffic Loading of \( 5.80 \times 10^7 \) ESAs.
