Determine the effect of pavement albedo on urban heat island effect, as well as pavement design and how it changes with time for all pavement types. This will require a combination of analytical modeling, material characterization, and empirical measurements. Provide tools and guidance to apply these relationships to sustainability rating systems and pavement design.
- Quantify the rate and magnitude of albedo change by pavement type and time.
- Develop models to determine the relative impact of albedo on heat collection, storage, and transmission potential associated with the developed albedo rate functions by pavement type and material constituents.
- Determine the level of significance of the pavement albedo relationships on the outcome of at least two pavement sustainability rating tools and one pavement design procedure.
- Provide recommendations for use of the albedo rate function model on choosing appropriate pavement albedo inputs for pavement sustainability rating tools and pavement design tools.
