This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

lDOT Mechanistic Based Design Procedure was used to evaluate the performance of concrete pavements being tested in Mn/ROAD. To accurately evaluate the probably performance of the pavements, fatigue characteristics of concrete used in Mn/ROAD had to be determined. Fatigue tests were run on simply supported beams, fully supported beams and fully supported slabs to evaluate the fatigue behavior of concrete using the different types of specimens. Results show that when interpreted in the conventional manner using Whaler diagram, the fatigue responses were the same with all three specimen types. However, the strength of the concrete at first crack was about 30 percent higher in the fully supported slabs than for the simply supported beams. The slab specimens also showed a much longer performance life between first crack and full cracking than the beam specimens. These results indicate a significantly longer fatigue life for the slabs than predicted using the strength data from simple beams. When the findings were applied to the concrete pavements in Mn/ROAD, using the lDOT Mechanistic Based Design Algorithms, the conclusion was that the pavements should not have failed. Results from Mn/ROAD show no evidence of structural distress at this time, thus partially validating the lDOT Mechanistic Based Design Procedure.
