<br />RATING 30
<br />FAIR —
<br />Structural improvement required
<br />Roads show first signs of needing
<br />strengthening by overlay. They have
<br />very severe surface raveling which
<br />should no longer be sealed. First
<br />longitudinal cracking in wheel path.
<br />Many transverse cracks and some
<br />may be raveling slightly. Over 50% of
<br />the surface may have block cracking.
<br />Patches are in fair condition. They
<br />may have rutting less than �fz" deep
<br />or slight distortion.
<br />� Longitudinal cracking;
<br />early load-related
<br />distress in wheel path.
<br />Strengthening needed.
<br />♦ Slight rutting; patch
<br />in good condition.
