What is the difference between Highway and Airfield pavement?
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 giRead more
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.

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.
