HOW TO COMPUTE VERTICAL CURVE DIMENSIONS

VERTICAL CURVE DIMENSIONS:


 C R L D Track Length
30 3' 3' 9 5/8" 3' 1 3/4"
45 3' 4  2 7/8  1' 9 1/8" 4' 8 1/2"
60 3' 5'  2 3/8" 3 6 3 3/8
30 4' 1 7/8  4 2 1/4
45 4' 5 7 7/8  2 4 1/8  6 9 3/8
60 4' 6 11 1/8   
30 5' 1 4 1/8  5 2 7/8
45 5' 7 13/16 2 11 1/8  7 10 1/4
60 5' 8 715/16 10 5 5/8

For an elevation change greater than shown on the above charts, solve for the remainder

Remainder -- Actual Elevation Change (Vertical Drop) -(minus) D (Minimum Drop) See chart

Then use remainder to solve for S and L

Calculation Example

Given - 4 radius, 60 degrees, 9 drop, vertical curve

S=0 (For minimum rise) S = 5 x 1.155 L = 5 x .577 + Minimum L
Total Drop 9  = 5 - 9 5/16   = 2 - 105/8 + 6 - 111/8 
Less Minimum Drop 4   = 9 - 93/4 
Remainder = 5
