Prepare an engineering report for the following abstract
Abstract
This report is based on the four tests which were carried out on the laboratory to help gain concepts in Highway Engineering. Highway Engineering being a broad area of study involves the study of both foundation of the subbase and the design of the pavement surfaces. These two areas of study were involved in the laboratory experiments which were carried out.
The experimental work involved tests on bitumen and tests involving the California Bearing Ratio. The test on bitumen are carried out prior the design of the pavements so as to know the important parameters affecting the pavement. Pavement are always exposed to adverse environmental condition among them being temperature. In the experiments carried out on bitumen; softening point, the needle penetration test and the viscosity of cutback bitumen test, it was observed that temperature and affected the softening point and also the fluidity of bitumen.
On the soil test, various experiment were carried out on the sample soil among them being the compaction test, the % moisture content test, the swelling and the CBR test. The maximum dry density of the soil and its corresponding optimum moisture content were achieved. Through computations, the recorded penetrations and their corresponding forces in the CBR test helped in getting the CBR at 2,5 and 5.0 mm where the highest value were considered. The experiments carried out were compared to the expected results where no much discripancy were observed.
Suppose that the probabilities are , respectively , 0.6, 0.2, 0.1 and 0.1 that an income tax form will be filled out correctly , that it will contain an error favoring a taxpayer , that it will contain an error favoring the government
Describe the equation for charging a water tank. Use: H= 2m, A_s = 1m^2, density water = 1000kg/m^3, K = 2000kg hr^-1 Mass flow in = K t. Calculate how long will it take to charge completely the tank
Measurements indicate that to cause this flow the force acting on the contents of the control volume is 40i lb. Determine the net rate of flow of linear momentum through the control surface.
Consider an asset that costs $712,000 and is depreciated straight-line to zero over its eight-year tax life. The asset is to be used in a five-year project; at the end of the project, the asset can be sold for $184,000. If the relevant tax rate is 35..
Define flow at a hydraulic jump (upstream and downstream) in terms of the types of flow and corresponding Froude number. What is the depth of water at each section (upstream and downstream) compared to critical depth
A differential leveling loop began and closed on BM bridge (elevation 103.895m). The plus sight and minus sight distances were kept approximately equal
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
Hurricane Flintstone has knocked out the power to your home. Your neighbor has the Bonda generator in the next problem and they have graciously extended a 100 foot extension cord to your home, which has a resistance of 0.0075 ohms per foot of wire (p..
