Truck Modeling Along Grade Sections
(Virginia Tech, 2001-05-11)
This research effort first characterizes the trucks traveling along US highways by analyzing data from Interstate 81. It is hypothesized that I-81 is typical of US highways and thus can provide some insight into typical ...
Experiments and Analysis of Water-filled Tubes Used as Temporary Flood Barriers
(Virginia Tech, 2002-04-26)
Geosynthetic tubes filled with water are considered. The tubes can be used in applications to resist rising floodwaters. They can also be used to form breakwaters and protect shores from erosion. This thesis considers ...
STABILIZATION OF SOFT CLAY SUBGRADES IN VIRGINIA â PHASE I LABORATORY STUDY
(Virginia Tech, 2005-05-10)
Many pavement subgrades in Virginia consist of wet, highly plastic clay or other troublesome soils. Such soils can be treated with traditional lime and cement stabilization methods. Alternatives, including lignosulfonates ...
A Conceptual Framework for an Enterprise-Wide Geospatially Enabled Information Management System for Transportation Right-Of-Way Business Processes
(Virginia Tech, 2010-05-13)
Right-of-way business processes have been identified as one of the areas where information bottlenecks occur in transportation agencies, not only because of the amount of information involved, but also because of the ...
Long Term Hydrologic Effects on Stream Health from Residential Development Patterns
(Virginia Tech, 2002-07-08)
In this study eight residential development scenarios are created for the mostly undeveloped Back Creek Watershed outside Roanoke, Virginia. The development scenarios include low, medium (cluster), medium (conventional), ...
