LAYING OF A REVERSED CURVE. Sketch it after
LAYING OF A REVERSE CURVE USING TRANSIT AND TAPE OBJECTIVE: 1. To be able to lay a reverse curve by incremental chords and deflection angle method. 2. To master the skill in leveling, orienting and using the transit/theodolite effectively 3. To work cooperatively with one's groupmates and efficiently perform the required task. Instruments: GIVEN: 1. 2 range poles ict CURVE No Curve 2. chalk (for pavements) 3. 2 sets of marking pins (for soft ground) by 9.34 D 7.211 4. 50 meter tape 5. theodolite or transit di 2.73 di- 2.12 PROCEDURE: da 6.60' dz. 0.23 1.
