What are the best economical pavement design method for road construction?
When is scarification needed for road work?
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 conditioRead more

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 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.

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
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.
(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

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. DeRead more
Comparison of both is
Highway pavement
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.
