    Which type of pavement distress is characterized by a series of interconnected cracks forming a pattern resembling alligator scales?

    a) Block cracking

    b) Rutting

    c) Longitudinal cracking

    d) Fatigue cracking

    Answer: d

    Flexible Pavement Design:

    Calculate the required thickness of a flexible pavement using the AASHTO empirical design method for a given design traffic of 1,500,000 ESALs (equivalent single axle loads) and a CBR of 8.

    Convert the speed to m/s and substitute the values to calculate the stopping distance.

    Answer: Stopping Distance = 400 meters

    Pavement Life Cycle Cost Analysis:

    Perform a life cycle cost analysis for a pavement design with an initial construction cost of $1,000,000, a service life of 20 years, and annual maintenance costs of $50,000.

    Solution:

    Using the formula for life cycle cost:

    Life Cycle Cost

    =

    Initial Cost

    +

    (

    Annual Maintenance Cost

    ×

    Service Life

    )

    Life Cycle Cost=Initial Cost+(Annual Maintenance Cost×Service Life)

    Given: Initial Cost = $1,000,000, Annual Maintenance Cost = $50,000, Service Life = 20 years.

    Calculate the life cycle cost.

    Answer: Life Cycle Cost = $2,000,000
