2. For a highway curve the following are given: I62°30″, Ra 220 m and the station of Pl 25+10.552. Spirals, with length 100 m, will be used at each end of the circular arc. a. Calculate the stations for TS, SC, CS and ST points on the spiraled curve; b. The curve will be laid out with a total station, by deflection angles and total chord lengths. Stationing is 25 m. c. Draw the curve to an appropriate scale and indicate the location of the stations. Note: The spiral from TS to SC will be laid out from a setup on TS, the circular part will be laid out from a setup on SC and the spiral from CS to ST from a setup on ST
