CHAPTER 3 CURVES Section I. SIMPLE HORIZONTAL CURVES TYPES OF CURVE POINTS By studying TM 5-232, the surveyor learns tolocate points using angles and distances. Inconstruction surveying, the surveyor mustoften establish the line of a CURVE for roadlayout or some other surveyor can establish CURVES of shortradius, usually less than one tape length, byholding one end of the tape at the center of thecircle and swinging the tape in an arc, marking as many points as the radius and length of CURVE increases,the tape becomes impractical, and thesurveyor must use other methods. Measuredangles and straight line distances are usuallypicked to locate selected points, known asstations, on the circumference of the CURVES A CURVE may be SIMPLE , compound, reverse, orspiral (figure 3-l).
