Waterproofing roads using nano-modified emulsion could reduce potholes, expert says

University of Pretoria (UP) Department of Civil Engineering Professor Gerrit Jordaan has said the key to solving South Africa’s pothole problem is using modified emulsion and nano-materials, which he noted was inexpensive and already being manufactured in South Africa. During a session of the Southern African Transport Conference, which is being held from July 10 to 13, in Pretoria, he explained that the main problem with pavement structure was water infiltration and resultant cracking, stressing the need for preventing potholes by resurfacing roads with the correct materials instead of having to keep fixing potholes that reappear.
