3-In order to design the thickness of JPCP concrete pavement based on AASHTO design using dowel bar in transvers joints seams with concrete comb of a suburban freeway with initial serviceability index (Pi) of 4.5, a report of geotechnical studies related to determining the effective modulus of subgrade reaction was conducted. The pavement design consists of subgrade soil and a cement treated base (CTB) layer with thickness of 15 cm with an elastic modulus of 1X00000 and assuming the thickness of concrete surface design is 25.4 cm. (10 inch) According to the borehole, the average distance between subgrade depth to rigid foundation (DSG) is about 1.5 meters (5 ft). The relative damage of other months from May to March was 0.6, 0.7, 0.55, 0.6, 0.7, 0.65, 0.5, 0.45, 0.75, 0.6, 0.55, respectively. Note: (To determine the elastic modulus instead of (x) place the digit on the right side of the student number. For example, if the student number is 39912340486002, the coefficient is 1200,000.) A: Is it desirable to complete the table with a conservative approach for April? B: Determining the effective modulus of subgrade reaction(K) design? (3 scores). Relative damage K value due to DSG Composite k value Elastic modulus of base 1X00000 Roadbed resilient modulus (Mr) Month 5000 April C: It is desirable to determine the flexural strength of the design if there is no workshop documentation of concrete resistance tests, but is the characteristic compressive strength equal to the minimum permissible bylaws? (1 score) D: Determining the thickness of the required concrete surface if the drainage coefficient is 1, the design traffic is 10 million ESAL. In addition, if the values are determined from the related tables, the maximum value should be selected? (2 score) E: If this type of pavement is designed based on JRCP, it is desirable to design only ribbed mesh network design for 4-lane highway (2 lanes in each direction) with a lane width of 3.65 meters (12 feet) and the length of 12 meters (40 feet) and the assumption of the thickness of the concrete pavement 25.4 cm (10 inches). for students with odd student numbers only design the first lane and for students with even student numbers only design Second lane, as shown below? (Draw in figure) (3 scores) Good luck -p. hayati Median Lane 1 Lane 2
