After watching a contestant on the Spanish version of the show use a technique known as spherification (the controlled jellification of a liquid to form spheres), Dr Alvaro Garcia, from the Nottingham Transportation Engineering Centre (NTEC), began exploring how the addition of microcapsules of oil to asphalt could be used to create self-repairing road surfaces. The idea is that as cracks appear in the road the capsules break open, releasing the oil within and softening the asphalt […]
