SIDE SLOPES OF THE HILL ROADS SHOULD BE AS GENTLE AS POSSIBLE AS REQUIRED FOR THE STABILITY OF CUTTING WORK, IN PICK, JUMPER AND THE BLASTING WORKS

In hilly areas it is necessary to verify the suitability of natural soil for road works under construction and in order to determine the suitability of a particular soil it is essential to know the proportions of each material in the soil and also to know whether the particular material possesses the properties required of it. For instance, a road soil that is 95 percent sand will not cohere, and a clay that does not possess the property of cohesion is useless as a road material and will create problems for which it is necessary to protect the required side slopes of the road cutting, so that it may not fall during the rainy season for which the work of excavation of soil in pick work is done in 1:2 ratio of horizontal and vertical components of the cutting profile and in case of hard blasting work it should be done in the ratio of 1:16 that is 1 horizontal and 16 vertical components of the profile of cutting. Similarly in the case of jumper work it should have 1:4 in soft work and 1:8 in hard work but the construction agencies are taking no cognisance of the side slopes required as gentle as possible for which strict compliance of the side slopes of road cutting is necessary under code for consideration failing which it may fall during the rains . Soils formed as a result of disintegration of rocks, carried over a long time and the area of non alluvial soil has usually an uneven topography and hard beds and there is no such problem of land slides however it is necessary to protect the slopes of the required stability and suitability of the soil for cutting and used for the construction of road. Different types of soils are used as per their suitability, stability and cohesive strength of the natural slopes of the soil protected for the permanent existing slopes of the adequate bond with the material like pick work, jumper work and the blasting work or the hard blasting work
