A DOT is responsible for maintaining a large network of roadway mileage. The results of an annual survey are as follows:

Group A: 60% of total mileage with a PCR between 90 and 100

Group B: 10% of total mileage with a PCR between 70 and 79

Group C: 30% of total mileage with a PCR between 80 and 89

Using the matrix above. Determine the condition of the network in (a) 2 years and (b) 3 years.
