The article examines the impact differences between producing concrete and asphalt. Both materials are widely used in the construction industry. Construction activities account for a large portion of greenhouse gases. Therefore, it is important to consider the Life Cycle Analysis (LCA)to reduce environmental impacts. In this study, the material processes were inputted into an LCA program called SimaPro. The database usedfor the study was Ecoinvent as it is one of the major databases within SimaPro. The materials were compared against impacts per kg of materialproduced as the functional unit. Each process was created using the materials, energy and transportation required to produce the materials. Waste streams were also included in the process to determine the impacts after the product was done with its useful life. Using the ReCiPemethod, an LCA was conducted. Midpoint and endpoint categories were examined for both the productions. The processes had similar resultsfor the human health and ecosystems categories; however asphalt was marginally higher for both. Asphalt had exceeded concrete in the resourceimpact category by 100 mPt. The results indicate that concrete is the more sustainable building material. Determination of various impactsof the materials is important for material selection.
