By: M.S.Yatnatti: Editor and Video Journalist Bengaluru : It is pertinent to note that potholes are not formed by BBMP or BDA as they happen every were in the world during rainy season in asphalt roads . A pothole is a type of failure in an asphalt pavement, caused by the presence of water in the underlying soil structure and the presence of traffic passing over the affected area .Despite hundreds of crores being spent annually and promises being made by the government, there is no noticeable difference in the state of Bangalore's roads. With tens of thousands of potholes and regular accidents, public complaints and media coverage have continued to rise.
Create STF to fix potholes problem : Let BBMP create a Pothole special task force (STF) with a chief engineer heading it with necessary equipments and trained staff to fix the potholes on war footing as and when they are formed .:Instead of spending money every time and every year in a unplanned manner BBMP can minimize the expenditure with special task force . With money once again being earmarked the need for this campaign to hold the BBMP accountable is more important than ever. Even after the countless deadlines given by leaders and various promises being made my BBMP officials, the state of Bangalore's roads is pathetic.We must take responsibilities into our own hands and ensure proper spending of the money to fix the potholes. Every year, the problem of potholes arises and every year crores of rupees is spent. There is public outrage and media coverage around it and the problem of potholes are temporarily fixed. A part of the money allocated is used to actually fix potholes while the rest of it remains stagnant or just disappears. Cheap incompetent engineers and contractors who get the work every year are contracted to fill the roads, and they do so with gravel and dirt, and sometimes pour a layer of asphalt over the potholes . The shoddy job results in potholes coming back, and the entire cycle repeats itself resulting in public money being misused. The BBMP needs to ensure that all potholes identified are properly fixed with the help of experienced contractors and engineers for a long-term solution to this problem.
PotholeWikipedia definition: A pothole is a type of failure in an asphalt pavement, caused by the presence of water in the underlying soil structure and the presence of traffic passing over the affected area. Introduction of water to the underlying soil structure first weakens the supporting soil. Traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement.
How Do Potholes Form? : Potholes are holes in the roadway that vary in size and shape. They are caused by the expansion and contraction of ground water after the water has entered into the ground under the pavement. When water freezes, it expands. Think of when ice cubes are made. A tray full of water is put into the freezer, and when you remove the tray from the freezer, you will notice the water has expanded. This same effect happens when water gets into the ground under the pavement. If it has a chance to freeze, it will take up more space under the pavement, and the pavement will expand, bend, and crack, which weakens the material pavement. Then when ice melts, the pavement contracts and leaves gaps or voids in the surface under the pavement, where water can get in and be trapped. If the water freezes and thaws over and over, the pavement will weaken and continue cracking.As the weight of cars and trucks pass over the weak spot in the road, pieces of the roadway material weaken, which will cause the material to be displaced or broken down from the weight, creating the pothole.What happens when salt is brought into the picture? Water will freeze at 32 degrees Fahrenheit. When salt is used, it lowers the temperature that water will freeze. This creates an artificial freeze-thaw cycle that permits more occurrences of the damaging cycle to occur. This happens more often in the spring because of the melting that takes place and because the temperatures fluctuating above and below the freezing point very frequently.
