Evaluation of the Albedo-induced Radiative Forcing and CO2 Equivalence Savings: A Case Study on Reflective Pavements in Four Selected U.S. Urban Areas
(2017-08-01)
There is a growing interest in developing cool pavement strategies to mitigate pavement’s impact on the global warming in recent years. One of the mitigation strategies is by increasing the solar reflectance (or albedo) ...
Research Brief: Quantifying the impact of pavement reflectivity on radiative forcing and building energy demand in neighborhoods
(2017-03-13)
Albedo is the measure of the fraction of solar energy reflected by the Earth’s surface. High-albedo surfaces, which are lighter in color, absorb less sunlight energy and reflect more shortwave radiation. The change in ...
Accounting for Rehabilitation Activity Uncertainty in a Pavement Life Cycle Assessment using Probability and Decision Tree Analysis
(National Ready Mixed Concrete Association, 2015-08-12)
In any life cycle assessment (LCA) for pavements, the designer must decide on which rehabilitation activities will be used to maintain the pavement over the analysis period. While this sounds simple, the fact is that there ...
The impact of surface albedo on climate and building energy consumption: review and comparative analysis
(Transportation Review Board, 2015-08)
This paper presents a state-of-the-art review of the existing research on the climate impacts of albedo. Different analytical approaches and modeling works are synthesized and discussed.
Supplementary Information for Comparative Pavement Life Cycle Assessment and Life Cycle Cost Analysis
(MIT Concrete Sustainability Hub, 2014-07)
The MIT Concrete Sustainability Hub (CSHub) is conducting life cycle environmental and cost analyses of pavements under a wide range of contexts. The analyses involve the comparison of new asphalt concrete (AC) and portland ...
