摘要
We have today load lengths in thousands of kilometers WE' cannot think of anv other types of long roads other than tar loads, in spite of road construction done in most correct presents considered technical manner, tat/asphalt toads require repairs very often as they develop pot holes and it can he called a global phenomena The efforts required in terms of time, money and labor arc rather tremendous. Since the roads get damaged irrespective of the agency (owners, builders, repairers), one cannot attribute am other reason, other than technical for the significant deterioration of road condition in a very small lime span. While studying the problem technically, a comparison of road and rail track designs was made and two points came to surface. (1) Unlike railways, there is no means of converting point loads to general loading in case of present road design. In rail design this occurs due to the rails themselves. (2) Unlike railways, again, there is no means of stopping material dislodging in case a small pot-hole gets created. In railway design the soil underneath the sleepers only gets pressed down due to load and traffic. Further, in older railway track designs they had employed hemispherical bowls to ensure that soil docs not get eroded. Keeping above points in mind and considering present road design to be inadequate, method or design of "Permanent Type Tar/Asphalt Road Construction and Repair In the use of steel grid below the road surface" is put forth as a novel idea that will significantly reduce road deterioration and save cost and inconvenience to the public.
