    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, speedRead more

    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.

What is the mobilization & demobilization cost of any project, in percentage?

    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 costsRead more

    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.

    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. Then it is laid down on-site to a decided level or thickness by a paving machine. Bitumen- This is the heaRead more

    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.

    Meridian lines, in addition to marking lanes, provide necessary guidelines, instructions, and restrictions on roads. Yellow and white are the most common ones. There is no difference in the roads marked by yellow or white lines as such, but only the instructions given by them are different. Their relative occurrence varies from country to country.

    Soild white line: a solid white line along the curb or between two lanes means that switching lanes and overtaking is disallowed until the line changes.

    Broken white line: a broken white line is found between two lanes or in the middle of the road. It means that switching lanes or overtaking is allowed and safe.

    Solid yellow line: a solid yellow line between two lanes means essentially the same thing as a solid white line. A solid yellow line along the curb means that parking at the side of the road is disallowed.

    Double solid yellow line: a double solid yellow line down the middle or between two lanes means that overtaking or switching lanes is dangerous and is not advisable although not disallowed. A double solid yellow line along the curb means that a specific waiting time by the side of the road is allowed, but parking and leaving is not allowed.

    Double yellow solid and broken line: This is a kind of double meridian line found in the middle between two lanes with one line solid and one broken. It means that drivers on the side of the solid line are disallowed from changing lanes or overtaking, but drivers on the side of the broken line are allowed switching lanes and overtaking.
