Objectives: Apply your gained knowledge on pavement design. Improve your team working skills. . Learn ho w to present your work in a technical and professional methods. Requirements: A 10 km major 4-lane highway is to be constructed. The distribution of axles same as shown in Table1 during 160 days, 3% annual growth rate, and 35% on the design lane, and a design period of 25 years. Table 1: Axle Distribution Data Load (kip) Numbers 40500 23774 12 14 16 18 20 24 26 28 30 32 34 12434 9558 4334 2612 1235 587 243 142 36 The soil material was tested in four locations along the proposed roadway site to characterize its strength. The CBR value of the subgrade was determined to be 45. The availabe materials for the pavement construction are shown in Table 2. Table 2- Available Materials Resilient Modulus Material Hot Mix Asphalt Crushed Agg. Base 45x10 psi 3.0x10 psi Design this pavement using Al and AASHTO methods and compare the designs. Use KENPAVE to determine the better performance design. A full technical report is required to be submitted to the consultant (me).Explanation / Answer
Consider a refrigeration cycle Carnot operating in a closed region in the liquid-vapor using 0.8 kg of Freon 12 as working fluid system saturated mixture. The maximum and minimum temperatures in the cycle are 20 ° C and -10 ° C, respectively. It is known that saturated liquid refrigerant is at the end of process waste heat, and the input net working cycle is 12 kJ. Determine the mass fraction of the refrigerant which evaporates during the process of addiction heat and pressure at the end of process waste heat.
