RISEvaluation of FWD Data for Determination of Layer Moduli of Pavements
Publisher: American Society of Civil Engineers
Abstract: Falling weight deflectometer (FWD) testing has been done extensively in the past to assess structural condition and determine the moduli of pavement layers. The set of modulus values for pavement layers obtained from the ...
Assessing the Life-Cycle Costs of Pavement Rehabilitation Strategies Used in Long-Term Pavement Performance Program
Publisher: ASCE
Abstract: The purpose of this study was to evaluate the life-cycle costs of asphalt pavement rehabilitation strategies using the Long-Term Pavement Performance (LTPP) program. For this study, 649 pavement sections and their respective ...
Field Assessment of Cold In-Place Recycled Asphalt Mixtures Using Accelerated Pavement Testing
Publisher: ASCE
Abstract: The objective of this study was to assess the performance of full-scale cold in-place recycled (CIR) asphalt sections using accelerated pavement testing (APT). A balanced mix design approach was followed to optimize the ...
Investigation of Thermally and Mechanically Balanced Structural Design of Insulated Pavements for Cold Region Applications
Publisher: ASCE
Abstract: Adding an insulation layer above the frost-susceptible layer in regular pavement structures was proved to be an efficient way to mitigate the influence of climates, such as frost heave and thaw weakening, on pavements in ...
Economic and Environmental Cost Analysis of Cold In-Place Recycling
Publisher: ASCE
Abstract: The purpose of this study is to evaluate and quantify the construction costs, energy costs, and environmental benefits of using cold in-place recycling (CIR) as a pavement rehabilitation technique. For this study, the costs ...
Storage Stability and Performance Assessment of Styrene-Butadiene-Styrene: Waste Polyethylene–Modified Binder Using Waste Cooking Oil
Publisher: ASCE
Abstract: This study investigated the compatibility of waste plastic, a serious environmental and recycling concern, with styrene-butadiene-styrene (SBS) in asphalt binders. An extensive storage stability analysis of binders modified ...
Understanding the Storage Stability of Polyethylene Modified Binders: A Laboratory Case Study Using Waste Plastics
Publisher: ASCE
Abstract: The aim of the study is to understand and achieve storage stable, compatible plastic-modified asphalt binders. In view of global plastic accumulation, the potentiality of polymeric waste plastics is evaluated as an asphalt ...
Compactability and Performance of Warm-Mix Additives at Lower Than Traditional Compaction Temperatures
Publisher: ASCE
Abstract: This study involves using warm-mix additives (WMA) to produce binders that can aid compaction at low temperatures during cold weather paving. For this purpose, a performance grade (PG) 58-28 asphalt binder was chosen as a ...
Evaluation of Impact of Mixing Method on Laboratory- and Plant-Produced Fiber-Reinforced Asphalt Mixture
Publisher: ASCE
Abstract: The addition of fibers to asphalt mixtures has the potential to improve the resistance of asphalt mixtures to cracking and permanent deformation (rutting). However, the state (distribution) of fibers in the asphalt mix is ...
