Abstract: Pavement performance can be represented either in load domain or time domain plots. The shape characteristics of pavement performance curves in the two types of plot are not the same. Plotting pavement performance in time ...

Abstract: In a highway asset maintenance management system involving more than one highway asset type, identifying an equitable optimal allocation of available budget to individual asset systems is a major challenge. This is because ...

Abstract: Traditionally, it has been a common practice to apply priority weights to selected parameters in the process of optimal programming of pavement maintenance. However, there are several issues associated with this approach ...

Abstract: A problem commonly encountered in airport pavement management is how to deal with pavement condition and performance databases with various extents of missing data. While robust imputation techniques are now available to ...

Abstract: Missing data in pavement condition and performance records of pavement management systems (PMS) are commonly encountered in practice. Imputation of missing data is often required in the analysis of pavement performance and ...

Abstract: For structural analysis of pavement design and pavement evaluation, there is often a need to compute critical-lane traffic loading from directional traffic-volume input. The accurate estimation of the lane distribution of ...

Abstract: Computer algorithms and graphical solutions for deflection-based closed-form back-calculation of rigid pavement properties are available. However, a solution in the form of regression equations would have useful practical ...

Abstract: Studies have shown that there exists a need to include agency and user values for pavement performance in engineering economic analysis of pavement strategies. Very little is known about the magnitudes and characteristics ...

Abstract: The geometry of invidivual humps and the spacing layout of humps are two key elements in the design of speed-control road humps. This study addresses the geometric design of individual humps. The paper examines the ...
