IT IS NECESSARY TO FOLLOW THE ROAD DESIGN STANDARDS AND ADOPT THE RESEARCH PARAMETERS,AS RELATED TO THE CLASSIFICATION OF ROADS .

Honourable Public Works Minister Govt of Himachal Pradesh Shimla has demanded suggestive measures from the public to improve the work and conduct of the department working for the welfare of common man demanding free and fair justice from the system of governance.As for as the suggestions required for improvement on the captioned subject matter deliberation required to be maintained by the department of Public Works is concerned it is necessary to follow the guidelines and yard sticks of the code and specifications as well as the design & Scope of the nature of duty and work for the safe design loads and concern .In the case of Hilly areas construction of road should be in cutting instead of filling for which necessary design of the curves and formation of sub grade ,sub soil drainage and moisture control is too necessary where required by the soil .The preparation of base and sub base course must be followed with proper camber and the super elevation as per design and scope of the existing crust of the soling , bearing and the pavement with bituminous surfacing as per requirement of the design & scope based on the vehicular traffic density as per the recommendations made by the various Indian Road Congress ,codes and specifications, time to time issued for the improvement of passengers car unit equivalents,as related to the road capacity and design standards of the classification of roads.The thickness of the pavement design is also depends upon the wheel load applied to the pavement,the intensity of stress reduces as the depth increases from the top of the surface, as such the thickness of pavement is increased for heavier loads and a larger total volume of traffic.Hence it is necessary to protect the safety measures by way of necessary follow up and mathematic calculations related to the thickness design of pavement and bearing capacity of the soil on which the road is to be built. It is also necessary to follow computation of traffic required for the CBR .For the design , the sub grade strength must always be assessed at the maximum moisture conditions likely to occur during the entire service life of the pavement and the CBR value determined accordingly, and the CBR values are based on the laboratory tests according to IS :2720 . Geometric road design standards should be followed as required for the acceptable compromise between the road users requirement and the construction costs which depends upon the geographical conditions of the area and for which the hilly area requires more funds as compared to the plains. As for as the road gradients are concerned the maximum longitudinal gradients are taken ,in relation to the design speed and the percentage calculation and the critical length of grade should be avoided as cause for the loaden trucks to reduce speed unduly. The department of public works too responsible to follow the IRC and IS standard of codes and specifications and do the needful accordingly in the interest of better work and durability required to improve the quality of performance related to the Road design standards which must be a research based parameter.
