    What is difference between Asphalt and Bitumen?

    In simple words, bitumen is a liquid that binds together asphalt. Asphalt-It is a mixture prepared by adding aggregates(sand, gravel, slag, crushed rocks) with appropriate binders like bitumen.

    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.

    Traffic Survey

    Precise surveys, studies, and scientific analysis of traffic is necessary for traffic engineering and find wide applications in anticipating future requirements of roads, the advancement of existing facilities, design aspects, pavement design, and traffic guidelines and control.
    Traffic surveys, better-called traffic census, covers all kinds of traffic, size, and weight, traffic flow, traffic volume per hour, and per day, including seasonal variations/annual variations, distribution in different parts of a road network, and distribution in different directions at intersections.

    Traffic volume counts can be obtained by the following methods:

    Manual Method

    Automatic Counters

    • Pneumatic Counters
    • Electrical Counters
    • Photo-Electric Cell Counters

    Moving Observer Method

    Presentation of Traffic Volume Study Data

    The information acquired from traffic volume are introduced in various structures for coming to suitable end results relying upon the reason for examines:

    (a) Hourly, daily, weekly, seasonal, and annual variations of traffic in the form of charts or graphs.

    (b) Annual average daily traffic (AADT) of the total traffic as well as classified traffic is determined.

    • Concept of PCU.
    • If measured for a short period, not for an entire year, is known as Average Daily Traffic (ADT).

    (c) Design hourly volume of traffic

    (d) Traffic flow-lines are drawn through the route with the thickness of lines being proportional to the traffic volumes.

    (e) Traffic flow distribution at road intersections

    The maximum degree of curve or smallest radius for a railroad is 3 degrees on a new main line track with a maximum grade of 1% compensated at 0.04% per degree of curve; therefore a grade in a 3 degree curve would actually be 0.88%.

    The maximum degree of curve or smallest radius for a railroad is 3 degrees on a new main line track with a maximum grade of 1% compensated at 0.04% per degree of curve; therefore a grade in a 3 degree curve would actually be 0.88%. For a highway it depends on what kind, where, typical traffic, speed limits, etc.  Degree of curve is the angle between the radii of a curve of a 100 foot chord which is chord definition. Highway departments usually use Degree of Curve as the angle between the radii of a curve of an arc of 100 feet. For curves 3 degrees or under, the difference between the definitions staked on the ground is inconsequential.

    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.

    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.
