The number of factors considered for flexible pavement is
The design factors that are considered are wheel load, soil, climate, pavement layer, drainage.
The contact pressure is given by
The contact pressure is given by P/A, where P is wheel load and A is area of contact.
The distribution of circular load was obtained by
The stress distribution for the circular load was obtained by Boussinesq, in which he assumed homegenous and elastic material.
The last step in the design of flexible pavement is
The last step in the design of the pavement is design of pavement thickness, after design of mix, design of sub grade, sub base and base.
If one or more wheels act as a single load then it is called as
If one or more wheels act as a single load then it is called as a equivalent single wheel load.
The pressure in pneumatic tyres should not exceed
The maximum tyre pressure in pneumatic tyre is 9.5kg/cm2.
The revised legal load of HCV in India in tonnes is
The maximum legal load in India is considered after revision as 10.2 tonnes, before it was 8.17 tonnes only.
The legal load considered in the benklemen beam method is
The maximum legal load in benklemen beam method is considered as 8.17 tonnes or 8170 kg.
The load dispersion is assumed at an angle of
The angle of the dispersion is assumed as 45° in the ESWL for the ease of construction and calculation.
The equivalent wheel load factors are calculated by using
The load factor follow the fourth power law for the calculation of VDF and load factor.
