A Portland Cement Concrete (rigid) pavement is to be designed using AASHTO empirical design method. The pavement should have an 8" granular sub-base having elastic modulus (Esb) of 50x103 psi. The resilient modulus of the subgrade is 5000 psi, and lying just 5 feet above rock strata (bed rock). (a) Determine the design k value, assuming loss of support factor (LSF) of 2. (b) Use the k value obtained from (a) to determine the thickness of the rigid pavement. Assume...

A new highway is to be constructed. Design A calls for a concrete pavement costing$90 per foot with a 20-year life;four paved ditches costing $5 per foot each; and four box culverts every mile, each costing $9,000 and having a 20-year life. Annual maintenance will cost $1,700 per mile; the culverts must be cleaned every five years at a cost of$350 each per mile. Design B calls for a bituminous pavement costing $45 per foot with a 10-year life;four sodded ditches...

A concrete mix design is needed for a residential street paving project in Detroit, Michigan. Pavement thickness is 8”, unreinforced, subjected to freezing and thawing and deicing agents are anticipated. The specified compressive strength is 4000 psi. Assume both Fine Aggregate (FA) and Coarse Aggregate (CA) are in saturated surface dry condition. Specific Gravity of Fine Aggregate (FA) = 2.71 Fineness Modulus (FM) of Fine Aggregate (FA) = 2.70 Specific Gravity of Coarse Aggregate (CA) = 2.65 Bulk Density of...

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...
