Seasoning of stone :

Generally, the action of having various changes in different seasons on the stone which are drying and wetting of stone which gradually forms the crack in stones which leads to the action of weathering action and forms inorganic small size materials is called seasoning of stone.

Seasoning refers to both drying and wetting cycles on one hand, and airing of stone, on the other hand. Dehydration during seasoning is more or less an irreversible process. Thus seasoning applied mainly to soft limestone; hard limestone seems to less affected by it. Stones have natural moisture, known as quarry sap. This quarry sap renders the stone blocks comparatively soft and makes them easy for working. Immediately after quarrying, a stone is soft and is easy to work with it so sized and primarily dressed, but polishing requires a fully seasoned and hardened stone.

Cable stayed bridges may look similar to suspension bridges. They both have roadways that hang from cables and both have towers. But the two bridges support the load of the roadways in very different ways. The difference lies in how the cables are connected to the towers . In suspension bridges, the cable ride freely across the towers, transmitting the load to the anchorages at either end. In cable stayed bridges, the cables are attached to the towers, which alone bear the load.

The cable can be attached to the roadway in a variety of ways. In a radial pattern cables extend from several points on the road to a single point at the top of the tower. In a parallel pattern, cables are attached at different heights along tower running parallel to one another.
