Often, a traditional design procedure is used wherein a designer sketches results which are based on computer applications and transmits this information via hard copy to a drafter, who re-enters it into a CAD system. The inefficiencies are clear and an obvious opportunity exists for productive gain....

 

The finite strip method was used to develop an automated procedure for determining the distribution of load on highway bridges subjected to both standard truck loads and overload permit vehicle loads. The distribution factors obtained by this procedure are used in the design and load rating of highway...

 

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 reviews the state-of-the-practice in low-volume road pavement design. The factors which dictate pavement design are discussed in terms of construction materials, environment, and traffic. Eight different design procedures are presented and discussed. These include the 1972 and 1986 AASHTO...

 

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...
