FIGURE 3. DISTRIBUTION OF PRESSURES PRODUCED BY MULTIPLE WHEEL
Tire Pressure: The intensity of stress at a given point in a flexible pavement is directly affected by the
tire contact area and the tire pressure. The major difference is stress intensities caused by variation in
tire pressure. Occurring near the surface, the pavement and upper base course are most seriously
affected by high tire pressure.
