Optimum use of pavement condition indicators in pavement management: Optimum use of pavement condition indicators in pavement management systems

Despite the significant progress made in the past three decades towards a comprehensive understanding of the processes and phenomena related to pavement deterioration and performance, it is freely admitted that a considerable gap in engineering knowledge will continue to persist well into the 21st century. Understanding pavement performance is a complex mission because pavement performance is controlled by many factors. Many studies have been conducted to answer a simple twofold question; how pavement performs and why it performs in this manner? This big question took the road agencies tens of years of research and investigations to answer and still no remedy answers have been found yet. This situation is true due to the fact that pavement is not a homogenous system or material that behaves in the same way at different locations. This book tries to answer some of these questions.
