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...
A concrete mix was designed for a concrete road pavement (i.e.
heavy mass concrete). A 28-day strength of 26 MPa is required. The
exposure classification for durability purposes is C. One hundred
laboratory test results on the controlling mix show a standard
deviation of 5.3 MPa (k=1.65). The density of crushed coarse
aggregate is 2850 kg/m3 and its dry rodded density is
1600 kg/m3 and the maximum size to be used is 10 mm. The
specific gravity of fine aggregate...
