Two tangents that intersect at an angle of 44°36' are to be connected by a compound curve. The tangent at the beginning of the curve at the PC. is 125.70 m. long and that at the P.T. is 155.6 m. long. The degree of curve of the first curve on the P.C. is 4°. Using arc basis. (a) Compute for the radius of the 2nd curve in m. (b) Compute the central angle of the 2nd curve in deg-min-sec. (c) Compute the central angle of the first curve in deg-min-sec.

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surf…
