How To Give Slope In Road By Auto Level

SLOPE PROVIDE IN ROAD

First off all we have an formula to for provide slope in road that is = Carriageway width X slope / 100

Now,

I will tell you how to provide slope in road. To provide slope on road follow the steps:

SETPS

Step 1 : We have to check what is the width of road in which we have to provide slope.

Step 2 : Then we see what % age of slope we have to provided in road that is given in drawing.

Step 3 : Now put the values in the formula we have 

Step 4 : Suppose that the width of carriageway or width of road is 7 meter. We have to provide slope                 2.5% in road.

Step 5 : Now put the all values in formulas 

        

                                            7x2.5/100 = .175mm

  Suppose that if the R.L value of upper edge of road is 210.635. then the lower edge of road we should substract  .175 mm from the 210.635. 

 

    210.635 - 0.175 = 210.460 the value should be 210.460 of lower edge.

Like that we can provide the slope of any road.

This formula is called Slope formula.

One thing to be remeber  : Like we take the width of carriageway 7 meter . actually we should take the reading in every 1.5 meter because to maintain the proper slope on road.
