a) 3 m
b) 2.7 m
c) 8.7 m
d) 9 m
BBD studies were conducted on a pavement at three points and the following data were recorded:
a) 0.28 mm, 0.63 mm and 1.96 mm
b) 0.82 mm, 0.36 mm and 1.69 mm
c) 1.82 mm, 1.36 mm and 0.69 mm
d) 1.28 mm, 1.63 mm and 0.96 mm
______ deflection is obtained as the sum of mean rebound deflection and standard deviation.
Find the standard deviation for a highway with heavy traffic if the rebound deflection values obtained atpoints are 220.127.116.11.18.104.22.168.1.and 1.38.
What is the standard temperature taken for the rebound deflection calculation?
It is not necessary to apply a correction for temperature if the testing temperature is lower than 35°C.
BBD studies were carried out on a highway pavement at a temperature of 40°C. The rebound deflection was found to be 1.mm. what would be the corrected rebound deflection?
a) 1.33 mm
b) 1.35 mm
c) 1.40 mm
d) 1.36 mm

a) 1.50 mm
b) 1.56 mm
c) 1.48 mm
d) 1.46 mm
What would be the corrected rebound deflection if the rebound deflection obtained from BBD studies is 1.mm? The test was conducted at 30°C on a clayey soil having a plasticity ofand a moisture content of 4.5%. The annual rainfall of the area is obtained asmm.
a) 2.57 mm
b) 1.57 mm
c) 2.75 mm
d) 1.75 mm
