BBD studies were carried out on a highway pavement at a temperature of 40°C. The rebound deflection was found to be 1.41 mm. what would be the corrected rebound deflection?

BBD studies were carried out on a highway pavement at a temperature of 40°C. The rebound deflection was found to be 1.41 mm. what would be the corrected rebound deflection? Correct Answer 1.36 mm

The correction for temperature is to be applied, as in the question the test temperature is 40°C, but the standard is 35°C. So, the correction to be applied is negative and it is taken as 0.01 per degree. Corrected Dc=Dc+(Standard temperature-field temperature)×0.01 Corrected Dc=1.41+(35-40)×0.01=1.36 mm

Five friends went for a trip where each carried a certain number of apples with them. The number of apples carried by C was 1 less than that by D, which was 5 more than the number of apples carried by E. The total number of apples carried by A and B both was equal to the average number of apples carried by C, D and E. If D carried more apples than B and they together carried 14 apples, which of the following is a possible value of the apples carried by A?
