Research road map

摘要

The Portland Cement Association (PCA) has published a research and development report that provides a critical review of existing literature and modeling tools related to life-cycle assessment (LCA) applied to pavements. The report, titled "Life Cycle Assessment of Pavements: A Critical Review of Existing Literature and Research," covers 12 published LCA studies and three LCA models. It finds that the existing body of work is flawed, preventing the widespread use of LCA by pavement engineers and policymakers.
