Interests: characterization of asphalt concrete materials; pavement fatigue and fracture; recycled materials; aging of asphalt materials; impact of climate change and sea level rise on pavement structures and infrastructure systems; and adaptation alternatives for resilient infrastructure
There is an increasing societal demand and need for sustainable practices to be incorporated into our daily lives and surroundings. Built infrastructure is a large part of our society and a key to the prosperity of individuals and regions. There is a significant opportunity to incorporate sustainability into the planning, construction, and maintenance of built infrastructure. Surface transportation facilities, e.g., pavements, provide a substantial opportunity as they require a significant volume of material that must be quarried or recycled, processed, transported, and constructed. There have been considerable advances in technology related to the design and construction of pavements as well as the materials that are used. The incorporation of recycled materials—from recycled pavements and aggregates to construction and demolition waste, roofing shingles, rubber tires, plastics, and glass—has become increasingly common. In addition, technologies such as warm-mix asphalt (WMA) have been used to decrease emissions and energy requirements and/or to enhance construction quality under a range of conditions. Fracture-resistant concrete, built with coarse reclaimed asphalt pavement (RAP), has been used to create multi-layered, functionally graded pavement systems with enhanced sustainability. If designed and executed properly, these modern approaches to pavement materials and design provide economic, environmental, and, often, duty-cycle extension benefits.
Approaches to evaluate the impact of various pavement materials on the environment, e.g., life cycle assessment (LCA) methods and tools, have been developed and refined in recent years as well. The improved understanding of the contribution of pavement construction, maintenance, and operation to climate change has led to industry-wide changes in practices. Recent research has begun to explore the impact of climate change on pavement assets. Accordingly, approaches have been developed to assess vulnerabilities and to evaluate adaptation alternatives towards more resilient infrastructure in response to climate change.
The sustainability of pavements is clearly a hot topic of interest to researchers, practitioners, and agencies/owners of these assets. This Special Issue will include some of the exciting cutting-edge work that is being done by leading researchers around the world on sustainability issues related to pavement materials and technologies as well as on the assessment and evaluation of sustainability in regard to the impacts of pavements on and resulting from a changing climate.

A Sustainability perspective for unbound Reclaimed Asphalt Pavement (RAP) as a pavement base material”
By Christina Plati and Brad Cliatt
Abstract: The proposed paper aims to investigate Reclaimed Asphalt Pavement (RAP) materials for utilization as a pavement base/subbase material with the goal towards the increasing the reutilization of materials and the movement towards increased pavement sustainability. Reduced cost for materials and transportation of materials, overall environmental benefits and many other advantages have led to increased interests in utilizing RAP in pavements including as base materials for highway/roadway construction projects. The potential advantages of utilizing RAP as base materials are known; however, its overall application is still limited partially due to the lack of systematic evaluation studies for the parameterization of RAPs mechanical behavior in pavement design. With this in mind the current investigation focuses on the resilient modulus properties of RAP materials in terms of the material’s elastic response. Experimental data from tri-axial stress tests on specimens consisting of RAP, aggregates and a mixture of both materials are investigated. Varying concepts of constitutive modeling for the mechanical behavior of RAP materials are presented. Particular attention is paid to the required procedure for determining the constitutive constants of the constitutive models investigated for the aforementioned materials. A comparative analysis is applied and based on the related results, it is concluded that RAP can be utilized as base/subbase material in the framework of pavement sustainability, as its behavior under loading conditions can be simulated by using appropriate constitutive models in pavement design.
Title: Life Cycle Assessment Informed Maintenance and Rehabilitation Planning: Interstate 495 Case Study
Authors: Katie Haslett, Eshan Dave and Weiwei Mo
Abstract: As construction costs continue to rise and adequate amounts of funding continues to be a challenge, the allocation of resources is of critical importance when it comes to the maintenance and rehabilitation of highway infrastructure. A Life Cycle Assessment (LCA) methodology was used to compare maintenance and rehabilitation scenarios over the design life of a 26-km stretch of Interstate-495. Pavement International Roughness Index were determined using AASHTO’s PavementME System. Meanwhile, vehicle fuel consumption and emission factors were calculated using a combination of Google Maps, the U.S. EPA’s Motor Vehicle Emission Simulator, the SHRP2 Naturalistic Driving Study, and MassDOT’s Transportation Data Management System. The evaluation of pavement performance with realistic traffic conditions, varying maintenance strategies and material characteristics was quantified in terms of life cycle cost, Global Warming Potential (GWP) and Cumulative Energy Demand (CED) for both agencies and users. The inclusion of realistic traffic conditions into the use phase of the LCA resulted in a 6.4% increase in CED and GWP when compared to baseline conditions simulated over a week. Results from this study show that optimization of maintenance type, material selection and timing may lead to a 56% difference in operations cost and 68% difference in construction/maintenance cost.
