Probably not. Endocrine disruptors in the environment can result from degradation of certain polymers, releasing chemicals such as bisphenol-A (BPA), phthalates and other compounds. For example, materials made with BPA such as polycarbonates, are associated with endocrine disruption hazards, particularly for children. Generally food and beverage containers are made from polyethylene or polypropylene because these plastics are very inert. They aren't made with compounds associated with endocrine disruption. Since the proposed roadways were going to use recycled polyethylene pop bottles it shouldn't be a problem. However I'm skeptical about the idea on other grounds, I have real doubts about factors like durability and cost.
