Hey there Yusef Mehdizadeh,

When it comes to conducting a life cycle assessment (LCA) of asphalt production using OpenLCA software, having access to a reliable database is crucial. While there are several databases available, finding one that specifically covers bitumen might require a bit of digging.

One database you Yusef Mehdizadeh might want to explore is the ecoinvent database. It's widely used in LCA studies and offers a comprehensive range of materials and processes, including those related to asphalt production. However, the coverage of bitumen might vary depending on the version of the database you're using.

Another option could be the GaBi database, which also provides a wealth of data for LCA studies. While it may not be entirely free, it does offer trial versions or access through academic institutions.

Additionally, you Yusef Mehdizadeh might find relevant data in national or regional databases, depending on your location and the availability of resources in your area.

Lastly, don't forget to check out any research papers or publications in the field of asphalt production and LCA. Sometimes, researchers provide datasets or references that could be valuable for your study.
