Highways and in particular their pavements are the fundamental components of the road network. They require continuous maintenance since they deteriorate due to changing traffic and environmental conditions. Monitoring methods and efficient pavement management systems are needed for optimizing maintenance operations. Pavement performance prediction models are useful tools for determining the op...

The Indiana Department of Transportation (INDOT) is currently utilizing a profilograph and the profile index for measuring smoothness assurance for newly constructed pavements. However, there are benefits to implementing a new International Roughness Index (IRI)–based smoothness specification utilizing road profiles measured using inertial profilers. Technological advancements have improved the...

Due to traffic loading and weathering, highway pavements deteriorate starting immediately after construction. Many rehabilitation methods are available to bring deteriorated pavements back to an appropriate level of service for road users. One of these methods, chip seal, has been widely used in many states, including Kansas. This study evaluated the performance of chip seal treatments in Kansa...

Abstract The pavement crack causes the highway service life to shorten, safety hidden danger increase. low efficiency and high cost of manual inspection makes it difficult detect cracks. This paper proposes a fast efficient deep learning detection system. CRACK2000, an image segmentation dataset with complex interference background multiple types, is constructed based on perspective transformat...

This paper presents a model through which the cost associated with pavement warranty in performance based maintenance contracts are analyzed and quantified. Performance based maintenance contracts are eventually getting popular among the Highway agencies.These are long term pavement warranty contracts where the contractors are responsible for maintaining the pavement condition upto a certain sp...

The Heavy Weight Deflectometer (HWD) test is one of the most widely used tests for assessing the structural integrity of airport pavements in a non-destructive manner. The elastic moduli of the individual pavement layers “backcalculated” from the HWD deflection measurements are effective indicators of layer condition. Most of the backcalculation programs that are currently in use do not account...
