Assumption of a linear elastic system under static loading is questionable for structural response analysis of pavement-subgrade systems under dynamic nondestructive testing and moving wheel loads, especially if a deteriorated pavement is under study. Presented are the results of a parametric study using the three-dimensional finite element ABAQUS code; it investigates the effects of pavement d...

Many agencies use the AASHTO Guide for Design of Pavement Structures to design their pavement systems. The limitation inherent in this method is the empirical nature of the decision process, which was derived from a road test conducted almost 45 years ago in Ottawa, Illinois. The newly released Mechanistic-Empirical Pavement Design Guide (MEPDG), based on NCHRP Study 1-37A, has adopted a mechan...

Through the analysis and summary of research status and development trends of deck pavement technology of long-span continuous rigid frame bridge deck pavement at home and abroad, the impact factors of durability of continuous rigid frame bridge deck pavement, such as design flaw, constructional quality and overload are studied. This article will comprehensively analyze the cause of disease foc...

Pavement construction and repair history is necessary for several pavement management functions such as developing pavement condition prediction models and developing maintenance and rehabilitation (M&R) trigger values based on past repair frequencies. It is often difficult to integrate M&R data with condition data since these data are often stored in disparate heterogeneous databases. This art...

Pavement deterioration rate is very difficult to predict because of the complexities in determining the pavement condition rating or difficulty in collecting detailed data, particularly in absence of sophisticated equipment or trained staff etc. A wide variety of Pavement Maintenance Systems (PMS) are used, but unfortunately either these systems do not use a formalized procedure to determine th...

Texas currently has approximately 17,000 miles of load-zoned roads, the majority of which are posted at 58,420 lbs. These roads consist predominantly of thin pavement structures constructed in the 1940s and 1950s, originally designed to carry the lighter loads of those times. In 1989, the 71st Texas Legislature passed House Bill 2060 (HB 2060), which established a $75-per-county permit that all...
