Solution
Answer:-
PSI may be considered to be longitudinal roughness. No direct device is use for calculation of PSI.
Name of devices for calculation of roughness of pavement :-
(i)rod and level survey
(ii) Dipstick profiler
(iii) Profilographs
(iv) Response type road roughness meters.
PSI can be measured by help of roughness of road.
No direct formula is for calculation of pavement serviceability index of road. Only correlate with riding quality survey. Most important weightage to the parameters must be decided.
