Development of a Pavement Evaluation Method for Low-Volume Airfield Pavements
… operations to failure on marginal flexible pavements. Alternate Launch and Recovery Surfaces (ALRS) are being constructed for use only when the mission-essential runways are destroyed during an attack. Since ALRS pavements will only be used in contingency situations, an evaluation procedure …

Characterization of Emulsion Aggregate Mixtures
… are evaluated in the laboratory. In-service EAM pavement evaluation includes distresses, DCP, and non-destructive testing using the Falling Weight Deflectometer. The study concludes that EAM's are adequately characterized as an improved granular material.

Benchmarking Pavement Environmental Performance Using Data-Driven Modeling and Policy
… from the production of materials. However, pavement materials impact emissions throughout the pavement lifecycle, not just during production. This paper addresses how a new pavement evaluation system and policy framework might drive better solutions to reduce carbon emissions, from a climate …

Desempenho de pavimentos de baixo custo no Estado do Paraná
… on the performance of some non conventional pavements in the State of Paraná, Brazil, are presented. Initially, some aspects of the theory and practice of pavement evaluation are discussed. Two main conclusions can be extracted from that analysis: a) it is aparent the necessity for the …

A Pavement Structural Capacity Index for Use in Network-level Evaluation of Asphalt Pavements
… a structural index for use in network-level pavement evaluation, which facilitates the inclusion of the pavements structural condition in many pavement management applications. The primary goal of network-level pavement management is to maintain an acceptable condition of the pavements within …

Evaluation of asphalt stabilized layer equivalency factors for use in airfield flexible pavement design
… method has been used for Air Force airfield pavement design since the late 1920s. The procedures, calculations, and related nomographs have been updated to reflect developments in the pavement design, pavement analysis, and unique landing gear configurations and load levels introduced by new …

Investigation on the mechanisms of block cracking in asphalt pavements
Block cracking in asphalt pavements is a primary form of surface cracking but has been the subject of very few scientific investigations. The extensive nature of this cracking form often leads to significant maintenance costs and reduces the ride quality and service life of the pavement surface. …

Alternatives to PCI and MicroPAVER based maintenance solutions for airport pavements
Airport pavements need to be maintained for adequate health condition by implementing cost effective maintenance solutions. Traditionally, maintenance and repair techniques have been developed based on the minimum acceptable Pavement Condition Index (PCI). However, there are pavements which show …

Analytical study of computer vision-based pavement crack quantification using machine learning techniques
… a promising non-destructive approach for road pavement condition evaluation. The main objective of this study is to extract, quantify and evaluate important surface defects, such as cracks, using an automated computer vision-based system to provide a better understanding of the pavement …

Sensitivity of Distress Rate to Observed Distress Levels
… of Transportation (NMDOT) uses a composite pavement condition index to identify and rank roads for budgeting and scheduling repairs. NMDOT uses an index number called the Pavement Serviceability Index or PSI. A key component of this index number is the Distress Rate (DR) which is comprised …

Mechanistic characterization of thin asphalt overlays for pavement preservation
… a preservation treatment for rigid and flexible pavements to improve ride quality, extend service life, and reduce noise levels on pavements. However, compared to the conventional methods of mechanistic analysis, analyzing thin AC overlay is complicated as these layers are directly exposed to …

Assessing the Mechanical Response of Pavements During and After Flooding
… and a threat to the load carrying capacity of pavements around the world. In the aftermath of flooding, the pavement structure could be inundated and fully saturated. The significant increase of water within pavement layers may cause weakness and induce damage with traffic loading, subsequently …

Verification of Mechanistic-Empirical Pavement Deterioration Models Based on Field Evaluation of In-Service Pavements
… thesis focused on using a detailed structural evaluation of seven (three flexible and four composite) high performance in-service pavements designated as high-priority routes to verify the applicability of the Mechanistic Empirical (M-E) models to high performance pavements in the Commonwealth …
