Topic Summary: Context Dependent Pavement Life Cycle Analysis
July 17, 2019

While it is commonly believed that the environmental footprint of pavements derives only from their construction and materials, a large proportion of that footprint actually comes from their use...

Research Brief: Modeling the Freeze-Thaw Damage Mechanism in Cement
January 30, 2019

In this research brief we propose a new way to understand the cause of freeze-thaw damage in cement. While conventional thinking attributes the damage to pressure generated by expansion of water...

Research Brief: The Influence of Incorporating Uncertainties and Treatment Path Dependence in Performance-based Planning Analyses
November 9, 2018

With low funding and high backlogs for repair, state agencies must effectively allocate budgets for the maintenance, rehabilitation and reconstruction of highways. To assist this mission, CSHub...

Research Brief: Climate Change Mitigation Potential of Pavement Albedo
January 16, 2018

Albedo is the measure of how much solar energy is reflected by the Earth’s surface. Low albedo, or darker color, surfaces absorb more heat and reflect less shortwave radiation than high albedo, or...

Research Brief: The influence of analysis period on pavement network performance
November 15, 2017

Existing pavement management systems mainly explain and evaluate current conditions. Performance-based planning combines data about current conditions with models that estimate likely future...


Supplementary Information for Comparative Pavement Life Cycle Assessment and Life Cycle Cost Analysis

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...

Pavement Roughness and Fuel Consumption
August 23, 2013

How does pavement roughness affect a vehicle's fuel consumption? This report explores how roughness is measured, how different pavement materials deteriorate over time in terms of roughness, and...

Materials price forecasting
Back to the Future: Using Historic Prices to Improve Pavement Material Price Projects
August 23, 2013

The future price of infrastructure materials is challenging to predict. This report descibes a method developed by CSHub to predict future prices of concrete and asphalt by using the historic...
