Scientists from the Technical University of Delft began testing a new type of bio-organic concrete and asphalt, which can independently fix of cracks on the surface, as this type of concrete and asphalt contains a special bacteria, that in contact with water produces a limestone, which fills the cracks. According to researchers from the Technical University of Delft in the Netherlands, the new technology will be able to quickly rid the streets of the pits, and the city budget will not need to allocate any funds for road maintenance. Self-healing materials for bio-organic concrete and asphalt, which were created by scientists of Technical University of Delft, contains a specific granules of bacteria of the genus Bacillus spores and calcium lactate, which is a nutrient, which is necessary for the rapid growth of bacteria. Bacteria are dormant in the bio-bio-concrete and asphalt, while a crack into the asphalt or concrete become wet, which dissolves the nutrients and cause of the bacteria to produce a calcite, the main component of limestone, which fills all the cracks and restores the shape of the structures of concrete or asphalt, the bacteria fix as major defects and microcracks about 0.2 millimeters, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... crete.html
