Pavement Design:
New pavement design is to be constructed in 2026. The new
average daily traffic for commercial vehicles on the opening day
will be 1700. Use:
Growth rate = 6%
Subgrade CBR = 3%
Design life = 20 years

Using the AASHTO 1993 Flexible Pavement Design Procedure, design
a pavement cross section that will provide 10 years service. The
initial PSI is 4.2 and the final PSI is determined to be 2.5. The
subgrade has a soil resilient modulus of 18,000 psi. Reliability is
95% with an overall standard deviation of 0.4. For design, the
daily truck traffic consists of 400 passes of trucks with two
single axles and 350 passes of semitrailer truck with tandem axles.
The axle...

Pavement requires aggregate of specific size. Aggregates for a
highway pavement are extracted from a gravel pit. Based on
experience with this area, it is known that the probability of
good-quality aggregate is only 80%. In order to weed out
poor-quality aggregate, engineers on site use a quick test, which
is not entirely reliable. The probability that a good-quality
aggregate passes is 90%, whereas the probability that a
poor-quality aggregate will pass is 20%.
⦁ What is the probability that...

For the column and beam layout, find the required slab thickness
and spacing of #4 reinforcing bars, if the loading in addition to
self-weight, is 2 point loads of 2 kips at the third points of each
span (4 point loads total) f'c =4000psi fy = 60ksi d = hSLAB -
1in,
weight of reinforced concrete is 150pcf, width of beams - 12in,
space between borders of beams - 7ft.

Pavement performance is an important factor in pavement design
because it provides a framework upon which a judgement on the road
is either success or failure, which is associated with the ability
of the pavement to carry out the design loading. Based on these
statements, briefly discuss a distinction between the two different
types of failures.
