Abstract
As quality aggregate sources are depleted, there is a growing importance given to incorporating recycled co-products and waste materials (RCWMs) in new and rehabilitated pavements. An ideal goal would be using recycled materials to create long-lived, well-performing pavement and then being able to use those materials again at the end of their life to create new pavement, thereby effectively achieving a zero-waste highway construction stream. This would not only produce distinct cost advantages, but it would also significantly reduce energy consumption and greenhouse gas (GHG) emissions and eliminate the need for landfill disposal. Drawing from ISO standards and practices, this article reviews the recycling methods and definitions associated with the End-of-Life (EOL) phase and present various EOL considerations for asphalt pavements and the associated challenges to quantify EOL contribution in the pavement life cycle.

A shared goal of the Federal Highway Administration (FHWA) and the National Asphalt Pavement Association (NAPA) is to support and promote sustainable practices, such as pavement recycling and warm-mix asphalt (WMA). The use of recycled materials, primarily reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS), in asphalt pavements reduces the amount of new materials required to produce asphalt mixes, as well as the stream of material going to landfills. This is vital to the missi...

Certainly, one of the most cost effective and comprehensive infrastructure assets of the build environment is road infrastructure. The environmental impacts of this asset during its life-cycle drive researchers to create a foundational framework to quantify these effects. Life cycle assessment (LCA), a method for the assessment of all modules in a life cycle, has been examined to evaluate all the environmental modules and components of road projects due to constraints of environmental assessment...

Abstract With the pavement industry adopting sustainable practices to align itself with the global notion of habitable environments, there has been growing use of life-cycle assessment (LCA). A hybrid LCA was used to analyze the environmental footprint of using a reclaimed asphalt pavement (RAP) content in asphalt binder mixtures. The analysis took into consideration the material, construction, and maintenance and rehabilitation phases of the pavement life cycle. The results showed significant r...

Today's sustainability-driven systems require a product or process to be environmentally beneficial as well as cost-effective. This study used life-cycle cost analysis (LCCA) and life-cycle assessment (LCA) to consider the economic and environmental feasibility of using a high content of reclaimed asphalt pavement (RAP) in asphalt mixtures. The LCCA conducted in the study incorporated agency cost as well as the costs incurred by the user in the construction work zone. Initial construction as wel...

In-place recycling and reclamation of asphalt pavements provides agencies with the ability to optimize the value of in-place materials, minimize construction time and traffic flow disruptions, and reduce the number of construction vehicles moving in and out of the construction area. This report discusses the use of hot in-place recycling, cold in-place recycling, and full-depth reclamation. Information for this report was gathered by literature review, a survey of state departments of transporta...

Abstract This paper systematically studies the effects of asphalt foam characteristics and pulverized asphalt pavement (PAP) material attributes on foamed asphalt mix strength. A fracture face image analysis procedure was employed to quantify asphalt dispersion, which was key to establishing the relationships between material microstructural features and measured strengths. Foamability of asphalts was found to be one of the primary factors determining foamed asphalt mix quality. Foams with highe...

This pavement preservation topic has gained significant attention from pavement practitioners in the United States along with important support from the Federal Highway Administration, which has enabled several programs in pavement preservation. In the current SAFETY-LU and the upcoming Transportation Bill, the emphasis is on transportation infrastructure issues such as pavement preservation and faster rehabilitation/re-construction with the significant topic of the renewal of infrastructure. Pr...

Full-depth reclamation/recycling (FDR), or deep in-situ, recycling of damaged hot-mix asphalt (HMA) pavement with foamed asphalt (FA) and an active filler such as portland cement or lime can provide a stabilized base for a new hot-mix asphalt wearing course. Unlike other states and countries using FDR-FA, most California Department of Transportation (Caltrans) FDR-FA projects are on pavements with thick, cracked HMA layers over a relatively thin, weak natural aggregate base. Research was conduct...

Recycled Asphalt Pavement (RAP) usage has increased a lot from the last two decades. World highway agencies are attempting to use higher quantities of RAP to cope up with not only economic and green environment but also to save natural resource and comparable or even better performing hot mix asphalt (HMA) mixtures. Continuous damages of flexible pavements like rutting, moisture damage and thermal cracking reduces the pavement performance as well as riding quality. Studies have shown that high a...

The purpose of this study is to mitigate the carbon dioxide (CO2) emission from bitumen tank combustion unit in hot mix asphalt (HMA) plant. This study has been conducted by introducing the catalytic methanation method to reduce the CO2 emission which majorly contributed to the greenhouse gases emissions in atmosphere. The benefit of using the method is that a high amount of CO2 can be reduced without effecting the asphalt mixture properties which are very crucial to ensure high-quality asphalt ...
