    Mobilization and demobilization costs can vary greatly depending on the type of work being performed and what level of costs and logistics will be required to get the job rolling.

    Mobilization and demobilization costs can vary greatly depending on the type of work being performed and what level of costs and logistics will be required to get the job rolling. So, there isn’t really one rule of thumb to follow on all projects.

    But, mobilization should represent the actual costs of accumulating and coordinating all the necessary equipment, tools, materials, etc. – it shouldn’t typically be made up independently and without a sound basis. With that being said, mobilization costs tend to be under 10% and even as low as 2%. And as mentioned above, that should be pretty tightly tied to the actual costs of mobilizing and demobilizing the job.

    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.

    Comparison of both is

    Highway pavement

    • Cost is low.
    • Less toughness compare to airfield.
    • Design load is less.
    • Less hardness compare to airfield.
    • Compare to airfield, less construction cost and design cost.
    • Length of Highway payment is very high.

    Airfield pavement

    • Cost is high.
    • High toughness need.
    • Design load is very High
    • Need higher resistant to wear and tear due to aircraft trust.
    • Design cost and material cost is high due to rigid specifications and high level of construction practice.
    • Length of airfield pavement is less compare to Highway pavement.

    GIS is the software used to find capture, store, manipulate, analyze, and present all types of geographical data. The main purpose is to share the geographic location and other details of a specific point on the earth. It has multiple application in our daily lives especially in construction sectors, flood control e.t.c

     

    While GPS is a global navigation satellite system that gives us time, velocity, location, etc,. The main objective is the accuracy in Position on the earth.GPS works through a technique called trilateration, which collects information to output the information.

    Bituminous Macadam is a Binder which is used for the 24-meter & 12-meter roads where the traffic movement is heavy. This can be laid in two or more courses for the better compressive strength. This shall comprise of 5 TO 7 percentage of bitumen.

    Semi Dense Bituminous Macadam is a binder that is laid after the BM course to obtain smoother finish on road surfaces. This is used in small roads of width less than 9 Meters. This course is laid directly on the wet mix macadam in smaller roads with a thickness of 25-30 mm. This shall comprise of 3 to 5 percentage of Bitumen.

    I assume you are talking about flexible (asphalt) pavements. Sacrification is needed when the cuts, potholes and all deformations are such that :

    • The optimum moisture content required for proper binding can no longer be met.
    • The filler material won’t bend properly if just put judging by the condition of the pavement.
    • The peak daily traffic on the road, does not permit it to be safe without reconstruction.

    The entire bituminous layer until the depth of the craters is scraped off, and a new layer with fresh material is then applied to reconstruct the road.

    The coefficient of subgrade reaction is referred as the ratio between the pressure against the footing or mat and the settlement at a given point expressed as the coefficient of subgrade reaction which is defined as the ratio between the pressure against the footing or mat and the settlement at a given point which is expressed as ;
    ks = q/S

    where,
    ks = coefficient of subgrade reaction
    q = pressure on the footing or mat at a given point
    S = settlement of the same point of the footing or mat in the corresponding unit of length

    i. The value of k is independent of the magnitude of pressure.
    ii. The value of s has the same value for every point on the surface of the footing.
