a) As a pavement inspector, you are assigned to assess a pavement condition. Following photographs were taken during a survey from 2 locations of the pavement.

1. During the AASHO road test, ONLY flexible pavements were constructed and tested.a. Trueb. False2. The AASHO present serviceability rating (PSR) was considered an objective quantity used to establish the performance of highway pavement in terms of applied traffic.a. Trueb. False3. The AASHTO present serviceability index (PSI) correlates the PSR to actual pavement performance in terms of applied traffic, and select distresses.a. Trueb. False4. There is only one AASHTO PSI equation that applies to both flexible and rigid pavements.a. Trueb. False5. The AASHTO PSI scale ranges from:a. 0-5b. 0-10c. 0-100d. None of the above

Discuss the pros and cons of JPCP versus JRCP. What is meant by the mechanistic-empirical method of pavement design? Is it possible to develop a wholly mechanistic method of pavement design? Why?
