Chapter
Published equations for approximations of soil compression index in terms of in situ void ratio are varied and confusing. Many published expressions yield a positive compression index even for soils with zero void ratios. Furthermore, published expressions are normally based on a high correlation coefficient and limited test data. Significant measu...
Chapter
The list of published empirical models for approximating the compression index of fine-grained soils in terms of its liquid limit continues to grow. Many such expressions are justified based on high correlation coefficients using limited test data sets. Significant measures such as standard errors are often omitted. Some published models are applic...
Chapter
The settlement of organic soils is dependent on the relative proportions of organic and mineral fractions and the degree of organic solids decomposition. The characteristics of the organic and mineral fractions significantly impact organic soils behavior. Experimental compression data for peat moss and mixtures of organic fibers with kaolinite or f...
Chapter
The consolidation process in fine-grained soils involves changes in excess pore water pressure (EPWP) and void ratio with time. An analytical solution for this problem was presented by Terzaghi (1943). Their solutions included several simplifying assumptions and applied to a constant initial EPWP distributions with depth. The solution is widely use...
Chapter
Stormwater runoff directly correlates to the amount of impervious surfaces on a property. Impervious surfaces allow the water to fill up pipes and streams faster, increasing the potential for street and/or storm system flooding during heavy rains and increasing maintenance and repair requirements of the storm sewer system. In late 2005, The United...
Chapter
In late 2005, the United States Environmental Protection Agency (USEPA) performed a “wet-weather inspection” in Peoria, Illinois. They determined that the City needed to make improvements to the combined sewer system (CSO). Further, in 2006, USEPA and the Department of Justice (DOJ) found the city of Peoria in violation of the Clean Water Act (CWA)...

The majority of the money spent on infrastructure in the USA go directly to fund transportation systems and projects. The Departments Of transportation (DOT) in each of the fifty States set performance targets for each program within each State. The US Department of Transportation’s 30-year framework for the future, identified trends and choices fo...
