O Figure Q2b shows a solid and homogeneous section, where (31.25 mm, 41.54 mm) are its centroid coordinates (X , ỹ) relative to the axes origin, 0. The dimensions for the section in Figure Q2b are b1 = 15.75 mm , b2 = 15.75 mm, b3 = 62.50 mm, d1 = 75.85 mm and d2 = 20.25 mm. Calculate the second moment of area for the solid and homogeneous section shown in Figure Q2b about its centroidal x-axis. Give your answer to two decimal places. %3D %3D y b1 b2 di d2 b3

Drainage of Pavements

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 surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.
