Pavement Design and Construction Game 1

Based on AASHTO 1993, what is the performance period in flexible pavement design.

• The period of years that an initial pavement life will last before it need reconstruction.

• The period of time that an initial pavement structure will last before it need rehabilitation.

• The design of pavement that an initial pavement layers before reconstruction.

• The design of pavement performance that to sustain the traffic loading .

Concrete pavement distribute load over wide , therefore , the pressure given on the subgrade is high.

• True

• False

AASHTO 1993 Pavement Design Guideline was developed using _____________________ method.

• mechanistic empirical

• empirical

• precedent

Standard axle load used in ESAL calculation is:

• 8160 kg

• 816 kg

• 80 kg

What is ESAL

Assumed that there will be 500 000 ESAL for both directions ( 2 lanes per direction). Estimate the design ESAL with 80% lane distribution.

• 250 000

• 300 000

• 200 000

• 400 000
