Comparative Analysis of Performance Prediction Models for Flexible Pavements
(American Society of Civil Engineers, 2019)In the case of flexible pavements, efficient and realistic prediction models for the long-term process of their degradation are essential. The failure of flexible pavements due to cracking, surface deformation, disintegration, ... -
Effects of Rejuvenation and Aging on Binder Homogeneity of Recycled Asphalt Mixtures
(American Society of Civil Engineers, 2019)Despite the well-recognized benefits of recycling milled asphalt pavement material, some remaining challenges limit the reclaimed asphalt pavement (RAP) content in asphalt mixtures. Rejuvenators are frequently used to ... -
International Roughness Index Prediction of Flexible Pavements Using Neural Networks
(American Society of Civil Engineers, 2019)International roughness index (IRI) is a widely-accepted parameter that indicates pavement performance and ride quality. This study develops a prediction model for IRI using artificial neural networks (ANN) for flexible ... -
Comparison of Field Performance of Crack Treatment Methods in Asphalt Pavement of Texas
(American Society of Civil Engineers, 2019)Crack sealing and crack filling treatments have always been an important consideration to prolong the life of pavement among all pavement maintenance programs. Crack sealing uses a router to cut the crack to provide a ... -
Performance Comparison of Hot-Mix and Warm-Mix Asphalts with Cashew Nut Shell Liquid
(American Society of Civil Engineers, 2019)Hot-mix asphalt (HMA) is the paving material conventionally used all over the world, but the production of HMA at high temperatures of 150–180°C emits large amounts of particulate matter and harmful gases. Warm-mix asphalt ... -

Evaluation of the Anisotropy of Asphalt Mixtures
(American Society of Civil Engineers, 2018)A proper understanding of the anisotropic behavior of asphalt mixtures is required for an accurate multiaxial characterization of asphalt mixtures under different loading conditions. Asphalt mixtures are subjected to various ... -
Effects of Asphalt Mixture Type on Asphalt Pavement Interlayer Shear Properties
(American Society of Civil Engineers, 2018)This study compares the interlayer shear properties of pavement layers composed of different asphalt mixture types. Two dense asphalt mixtures (one surface mixture with Tennessee designation of D mix and another binder ... -
Forensic Investigation of Ten Asphalt Interstate Pavements with Varying Performance in Arkansas
(American Society of Civil Engineers, 2018)After 9–12 years of service, multiple sections of various interstates within Arkansas prematurely deteriorated. Four of these “poor” performing sections were compared to two “medium” and four “good” performing sections ... -
Sustainability Assessment of Recycled Asphalt Mixtures Based on Performance in Full-Scale Testing
(American Society of Civil Engineers, 2018)Public perception is that the cost and environmental impacts of pavement projects decrease when recycled materials are used in asphalt mixtures; most research studies support it. However, these studies usually analyzed ... -
