How are roads and pavements made? Can you simulate this using chocolate?Featured science project
I wanted to develop a hands-on activity related to my field of interest -- civil engineering with an emphasis in pavement and materials. Asphalt cookies were the perfect solution. Asphalt cookies are chocolate no-bake cookies. The process of making these cookies parallels the procedures used to produce asphalt pavements.
