    Disturbed soil sample is one in which the structure of the soil has been changed sufficiently that tests of the structural properties of the soil will not be representatives of in-situ conditions, and only properties of soil grains can be accurately determined.

    Undisturbed soil sample is one where the condition of the soil in the sample is close enough to the conditions of the soil in in-situ to allow tests of structural properties of the soil to be used to approximate the properties of the soil in-situ.

    Bitumen;

    BITUMEN is a petroleum product formed by the process of distillation of crude petroleum. It is available both in solid and liquid form. It is providing a good grip to the tyres as compared to the coal tar. Bitumen is available in three types that is; Rapid Setting, Slow Setting and Medium setting. In the modern era, we used bitumen instead of Coal Tar because Coal Tar is Carcinogenic.

    COAL TAR; Coal tar is derived from the coal.It is a black viscous liquid used as a sealing agent in old roads making all over the world. It is not used in the current era, due to the carcinogenic product. It is produced through the process of destructive distillation in the absence of air. Coal Tar not provide enough grip to the tyres of the vehicle and heat up quickly causes wearing out of tyres.

    Surface excavation involves the removal of the exposed layer of the earth surface, including any vegetation or decaying matter which could make the soil compressible and therefore unsuitable for bearing structural loads. Hence the depth will be vary from site to site, usually range of 150-300 mm.
