Q7: The attached worksheet was obtained in a laboratory design of asphalt concrete mixture for medium traffic. Carry out the required analysis and hence complete the table. Using the average results for each asphalt content, plot the necessary graphs and determine the optimum asphalt content based on air voids content requirement. Verify whether the optimum asphalt content determined will meet the GHA dense-graded specifications for medium traffic given in the table below. Use the following specific gravity values for your analysis: Bulk specific gravity of aggregates, Ga=2.65, Specific gravity of bitumen (asphalt), Gs=1.02 You should show sample computations involved in your analysis. Marks will be awarded forclarity of DEssentation.

Q13:D Question 5 1 pts The diameter of reinforcing bars in inch for No. 3 to No. 8 bars O is marked on the bar itself is not measurable as the bar may not be perfectly round can only be known after a measurement because it dependents on who manufactured the barSee Answer
Q14:D Question 6 5 pts As you may remember from the CE 533/CE 534 Mechanics of Materials class, the tensile strength of steel is measured by pulling the steel bar as shown below (Fig. 1) and recording the stress at different loading stages. As discussed in Lesson 2-Material Properties. for the concrete, however, the tensile strength is measured using either a flexural test (Fig. 2) or a split cylinder test (Fig. 3). Why the tensile strength of concrete is not tested similar to that for the steel?See Answer

Q16:Group B - Design of a retaining wall [10 marks] Consider the retaining wall shown in Fig. 2 built in Melbourne. The wall must hold a 4.5 m high uncontrolled backfill of crushed gravel (d = 30°. 7= 20 kN/m³). A vertical live-load of 7.5 kPa is applied on the soil surface ( = 0.7.= 0.4). The soil below the footing is the same as the backfill. The allowable bearing pressure is 150 kN/m², the concrete cover is 35 mm in the wall and 50 mm in the footing, the characteristic strength of concrete is 32 MPa, and its weight density is 25 kN/m³. The reinforcement is D500N20.
