This document discusses self-repairing roads that can heal their own cracks. It proposes using high-strength concrete with fibers coated in a hydrophilic material that attracts water. When cracks form, water acts as a healing agent. A 90km road built in India in 2015 uses this technique. The self-repairing mechanism makes the roads safer, longer-lasting, more sustainable and cost-effective than traditional roads. However, it is limited to concrete roads and requires skilled labor.
