Drivers the world may soon have respite potholes and cracks the road. Scientists from the universities of Bath, Cambridge and Cardiff have come with a novel and innovative solution to plugging gaps and holes roads and highways. They have created a bacteria-filled concrete to prevent cracks a road from becoming larger. The concrete is full bacteria that open when water seeps a crack. The bacteria burst open and inject limestone the crack, thus filling and repairing it to avert more serious damage. The scientists believe their discovery could considerably increase the lifespan roads, reduce repairs, and lower roadwork costs by to 50 per cent.

The new concrete could be good news the environment. Scientists estimate that over seven per cent the world's CO2 emissions come the production cement. If less cement is needed to repair roads, there will be fewer pollutants entering the atmosphere. Another benefit the new cement is a reduction accidents, injuries and deaths that result potholes. Thousands of motorists and pedestrians worldwide are killed because drivers swerve to avoid holes roads. There is also good news local governments. In Britain alone, least 40,000 drivers a year claim compensation for damages their car caused by potholes. The concrete could be put to use in the next 20 years.
