Geotechnical Aspects of Pavement Engineering

Familiarity with geotechnical aspects of pavement engineering is essential for the practicing pavement engineer. When designing pavements accurate characterization of the existing subgrade condition becomes a crucial task. In the past traditional geotechnical exploration and testing methods have been used to characterize existing subgrade conditions. However with the introduction of the Mechanistic-Empirical (ME) pavement design there is a need for improved and more appropriate methods of subgrade characterization for prediction of future pavement conditions with better accuracy. Hence this handbook will present a useful tool for practicing pavement engineers.
