Based on topography and climate of the location which factor is estimated?
The thickness is the most important factor that is designed as per requirement, pavement quality and pavement method are indirectly dependent on pavement design.
The warping stress is dependent on
The warping stress is due to the variation in the temperature of the pavement depends on length and width.
The first thickness assumed in pavement is called
The first thickness is assumed as a trail thickness, it may be later revised after design.
The factor of safety is the stress caused at
The stress caused is measured at the mid day due to wheel load and temperature stress.
The minimum factor of safety for rigid pavement is
The minimum factor of safety is 1.1 and if it doesn’t satisfy then the pavement thickness is revised.
The Westergaard equation was modified by
The Westergaard analysis gave low stress results so it was modified by Teller and Sutherland at edge.
If the flexural strength of a pavement is 45 and it’s stress is 40 then factor of safety is
The ratio of the flexural strength to total flexural stress is called as factor of safety.
The pavement thickness is usually assumed in rigid pavement as
The trail thickness usually assumed in rigid pavement is 25 cm , if it doesn’t satisfy then the pavement thickness is revised.
The temperature differential in coastal regions in India for a thickness of 25 cm is
The temperature differential in coastal regions in India is assumed as 16.2 degrees centigrade as recommended by IRC.
The minimum quality of thickness in the low volume roads is
The minimum grade required is M 40 but for low volume roads M 30 roads can be used.
