Overview Superpave has become the hot-mix asphalt mixture design method of choice of most state highway agencies across the United States. Early performance tests showed very rapid rutting failures. In order to determine the causes of the rapid rutting failures, Learn More>>
Various aspects of geosynthetic durability are addressed in this (one-hour) course in order to develop procedures that could be used to predict long-term strength losses of geosynthetics used in highway applications. This information is essential to... Learn More>>
This is an introduction to rigid pavement design. It is a basic treatment that will introduce designers to some important principles and terminology. In simple applications on real projects the information provided will give designers a good start in addressing... Learn More>>
The prime factor influencing the structural design of a pavement is the load-carrying capacity required. From an engineering design perspective, the thickness of pavement necessary to provide the desired load-carrying capacity is a function of five principal... Learn More>>
Overview The Strategic Highway Research Program (SHRP) developed a Long-Term Pavement Performance (LTPP) program to provide a consistent, uniform basis for collecting distress data for pavement performance. This course provides guidance to improve communications Learn More>>
Overview The use of recycled materials in pavement applications is on the rise. Factors contributing to the increased usage include the reduction of wear and tear on equipment required to haul new materials long distances; development and improvement of the... Learn More>>
