SOUND WAVES SAVE ROADS! By Antonio Nogalo
Roads European roads are built and repaired for billions of euros. All over the world people are developing better methods for design and quality control of materials. A problem today with roads is checking how sturdy and safely roads were built. Therefore more money is wasted for construction!
Sound Waves • A young scientist has developed a system that uses sound waves to display what a road looks like underground and whether it is being built properly. Sound waves will be utilized to build high quality roadways with great cost savings.
Damage • Sound waves can detect damage in bridges, tunnels, dams, and nuclear plants which will prevent dangerous and toxic accidents.
Materials • There are many materials in roads such as gravel, bitumen, air and water. It is unsure how roads will respond to future traffic and environmental loads. This is because roads are built in to the ground so it is hard to inspect them visually.
Nils Ryden • Nils Ryden is a researcher in engineering geology at the Faculty of Engineering, Lund University who developed the technology. He said that some roads only hold up for a few years because of weaknesses in the road that were overlooked.
THE END I HOPE YOU ENJOYED IT!
