Compute and tabulate the values for the ∆, T, E, M, LC, Station
of the PC and Station of the PT for the following highway curves:
3. Radius of 1650’ and a length of 635.44’, PI = STA 16+20.00’
For the following, compute and tabulate R or D, T, L, LC, E, M,
PC, PT, deflection angles, and incremental chords to lay out he
circular curves at full stations (100’). Develop and tabulate the
curve data, deflection angles, and incremental chords needed to lay
out the circular curves at full- station increments using a total
station instrument set up at the PC. (Essentially, develop a table
similar to Table 24.2.)
