Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which
Dec 21, 2009· Bridge planning, design, and construction is an important function of civil engineering. The bridge design will be basically determined by the type of bridge, such as the beam bridge or the suspension bridge.

availability of materials, their cost, and road use (weight and amount of traffic). Native soil is the least expensive, and often poorest material. Crushed aggregate is the most common improved surfacing material. Asphalt concrete is the best, smoothest, and most expensive surface. Dust palliatives may be used to reduce dust.

Careful consideration of the soil-type specific to your building site will help to ensure the stability of your foundation and integrity of your house for years to come. Unstable soil will need to be stabilized, most likely through mechanical compaction, and at a potentially high price.
Building material is any material used for construction purpose such as materials for house building. Wood, cement, aggregates, metals, bricks, concrete, clay are the most common type of building material used in construction. The choice of these are based on their cost effectiveness for building projects.
