A 10-in. concrete pavement without concrete shoulders is placed on an untreated subbas ehaving the k value 150 pci. Estimate the allowable corner deflection by the PCA erosio ncriterion if the pavement is subjected to 2 million applications of a given axle load .[Answer: 0 .0468 in . ]

A flexible pavement at an access road to a sportsstadium parking lot is designed with a 4-inch sand-mixasphaltic concrete surface, 5-inch aggregate bituminousemulsion base, and a 10-inch crushed stone subbase.There are 95 scheduled baseball and football games atthe stadium per year. The access road to the parking lotis three lanes in each direction (conservativelydesigned). The pavement was designed for recreationalvehicles with one 20K single axle and one 20K tandemaxle. There are 9,000 recreational vehicles estimated ateach event. Given that drainage coefficients are 1.0, theoverall standard deviation of traffic is 0.45, reliability is90%, and the soil's resilient modulus is 15,000 lb/in2,how many years will the access road last if the initialPSI is 4.0 and the terminal serviceability index is 2.5?

A flexible pavement was designed to have a 6-inch sand-mix asphaltic surface, 8-inch soil-cement baseand a 21-inch crushed-stone subbase (all drainagecoefficients are 1.0). The pavement was designed for800 12-kip single axles and 1600 34-kip tandem axlesper day in the design direction. The reliability used was90%, the overall standard deviation was 0.35, initial PSIwas 4.7, the TSI was 2.5 and the soil resilient moduluswas 2582 lb/in2. If the road has three lanes in the designdirection (and was conservatively designed), for howmany years was the pavement designed to last?

Take rotation of pavement by inner edge.

What does PG76-28 mean in pavement construction?

H.W: Design the pavement for an expressway consisting of an asphalt concrete surface, a crushed-stone base, and a granular subbase using the 1993 AASHTO design chart. The cumulative ESAL in the design lane for a design period of 15 years is 7* 10°. The area has good quality drainage with 10% of the time the moisture level is approaching saturation. The effective roadbed soil resilient modulus is 7 ksi, the subbase has a CBR value of 80, the resilient modulus of the base is 40 Ib, and the resilient modulus of asphalt concrete is 4.5 * 10$ psi. Assume a reliability level of 95% and So of 0.45.

The slab cracking is an unplanned longitudinal or diagonal structural crack(s) that extend through the depth of the slab. 10.
