Drivers the world at for from in into of over to up may soon have respite at for from in into of over to up potholes and cracks at for from in into of over to up the road. Scientists from the universities of Bath, Cambridge and Cardiff have come at for from in into of over to up with a novel and innovative solution to plugging gaps and holes at for from in into of over to up roads and highways. They have created a bacteria-filled concrete to prevent cracks at for from in into of over to up a road from becoming larger. The concrete is full at for from in into of over to up bacteria that open when water seeps at for from in into of over to up a crack. The bacteria burst open and inject limestone at for from in into of over to up the crack, thus filling and repairing it to avert more serious damage. The scientists believe their discovery could considerably increase the lifespan at for from in into of over to up roads, reduce repairs, and lower roadwork costs by at for from in into of over to up to 50 per cent. The new concrete could be good news at for from in into of over to up the environment. Scientists estimate that over seven per cent at for from in into of over to up the world's CO2 emissions come at for from in into of over to up the production at for from in into of over to up cement. If less cement is needed to repair roads, there will be fewer pollutants entering the atmosphere. Another benefit at for from in into of over to up the new cement is a reduction at for from in into of over to up accidents, injuries and deaths that result at for from in into of over to up potholes. Thousands of motorists and pedestrians worldwide are killed because drivers swerve to avoid holes at for from in into of over to up roads. There is also good news at for from in into of over to up local governments. In Britain alone, at for from in into of over to up least 40,000 drivers a year claim compensation for damages at for from in into of over to up their car caused by potholes. The concrete could be put to use in the next 20 years.
