Assume that the overall pavement evaluation of Interstate highways in a district consists of four categories: Surface distress index = 75, drainage index = 80, roughness index = 85, and structural index = 90. For all indices, 100 represents the best condition. Calculate the overall pavement index (OPI) of the interstate highways in this district, if the relative weights of different indices are 0.20, 0.25, 0.28, and 0.27, respectively.

Question
Assume that the overall pavement evaluation of Interstate highways in a district consists of four categories: Surface distress index = 75, drainage index = 80, roughness index = 85, and structural index = 90. For all indices, 100 represents the best condition. Calculate the overall pavement index (OPI) of the interstate highways in this district, if the relative weights of different indices are 0.20, 0.25, 0.28, and 0.27, respectively.
