A huge investment of money has been placed in constructing a
high-quality, well-finished highway network in the Kingdom of Saudi Arabia.
Roads are designed for lives of 15-20 years before any major maintenance is
needed. However, the asphaltic concrete layers of
these roads have been experiencing an early rutting distress, beginning a few
months to two years after opening to traffic. Excessive rutting in highway
pavement accelerates other forms of structural deterioration and creates safety
hazards. This problem, because of its extent and importance, has attracted the
attention and concern of highway authorities in Saudi Arabia. Many investigators
have studied this problem and tried to come up with measures to minimize,
correct, or prevent rutting.
In this work, a suitable model that can be generalized for rutting prediction
using local pavement properties, traffic, and environmental conditions is
sought. Two roads in the Eastern Province of Saudi Arabia were used for the
study of pavement rutting prediction.
