Voluntary turnover rates among truckload carriers are extremely high, ranging from 50 to more than 100 percent annually. These high turnover rates result in elevated costs for carriers in terms of recruitment and training as well as costs associated with reduced productivity and decreased customer satisfaction...

 

Fluctuation in temperatures significantly affects pavement stability and the selection of asphalt grading to be used in pavements. Ability to accurately predict the asphalt pavement temperature at different depths and horizontal locations based on ambient air temperatures will greatly help pavement engineers...

 

The objective of this report is to develop a profile of the U.S. containerized grain and oilseed export industry, including marketing activities, future expectations, information needs, and business practices. This report forms Phase I in a proposed two-phase analysis of the grain container industry....

 

The feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated in this research. This research was performed in two phases. The first phase consisted of modifying the GLWT to handle 15.2 cm (6 in) cores, developing a laboratory compaction procedure...

 

In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut...

 

The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent...

 

Transit service is playing an increasingly vital role in maintaining and improving mobility and economic well-being of rural populations in the North Central region. At the same time that transit service is increasing in importance, higher operating expenses and reduced federal subsidies are making management...

 

This report describes a study to evaluate the use of subgrade resilient modulus for the design of flexible pavements. The objectives of this initial study were to: a) investigate the relationship between resilient modulus and R-value, and b) develop a predictive equation for resilient modulus based on...
