Design the flexible pavement using Group index method and California bearing ratio method using the following data and compare the pavements.

Soil portion passing 75 micron sieve = 60%

Liquid limit = 43% and plastic limit = 28%

Area of the plunger = 19.6 cm2

Load at 2.5 mm penetration = 45kg

Load at 5 mm penetration = 68kg

Sub-base CBR = 30%

Base course CBR = 70%

Expected traffic = 900 vehicles per day.

A rectangular channel 2 m wide has a bottom slope of 0.01 and a roughness
coefficient of 0.017. A sluice gate 2 m wide is located in the channel. The sluice
gate has a contraction coefficient of 0.61 and a discharge coefficient of 0.58. The
depth of water just upstream from the gate is 2 m. The depth of water just
downstream from the gate is 0.5 m. Determine how far upstream from the gate
the depth of water will be within 1% of the normal depth.

List and explain at least three assumptionsthat are generally considered when using
vertical photographs to derive geometric information of the object space.

Using the rational method, determine the amount of runoff that would occur for a paved parking lot that is 100m * 50m and is uniformly sloped from one long edge to the other long edge at a rate of 2%. The time of concentration for this parking is 4 minutes. The five-year storm with duration of 4 minutes has an intensity of 10 mm/hr. The runoff coefficient for this parking lot is 0.80.آ [Q=0.166 CIA]
The runoff from part (a) is to be contained in a trapezoidal drainage ditch with the following properties: side slope = 2m horizontal run for every 1 m rise, width of invert = 2m, longitudinal slope = 0.005 m/m, and Manning's number = 0.08. If the maximum permittedآ depth of water is 100 mm, using Manning's equation for open channel flow, determine if the ditch will be able to accommodate the flow in part (a).

You are to carry out a research using the internet and identify at least five different innovative ideas for intersection or road design to improve Road Safety and/or traffic flow. For each idea, provide a description of the idea, a photo or illustration of the design, where has it been used, advantages and disadvantages of the idea, and the source of the information (internet webpage/link will be sufficient).

In practicing their profession, engineers may cause safety and hazards to another party or environment as a result of their unprofessional practices. Explain and assess the legal implications of these professional negligence in the engineering practices.

Describe any laws, regulations or policies that relate to the efforts of ensuring and governing low cabon, plastic free and green environment in Malaysia. Decide whether the existing laws in Malaysia are sufficient to regulate various issues pertaining to low carbon, plastic free and green environment. If yes, please explain why you think so and if not, please suggest any practicable enhancements to the existing laws or national policies in order to better improve the enforcement.

Q.In case of f(F,p,D,V,Mu,g), express F as a function of other physical quantities through Buckingam-pi method.

Sandstone pore of 20 mm in diameter and 100 mm long with porosity of 15% is prepared for
core flood experiment. The sandstone pore is fully (100%) saturated with water by injecting
water with viscosity of 1cp at volumetric flow rate of 20 cubic mm/sec. A pressure drop of 1
atm was recorded across the pore during the injection process.
i. What is the absolute permeability of the sandstone pore sample in mD?
ii. What is the pore volume of sandstone sample?
iii. The sandstone pore sample is flooded by oil with viscosity of 2 cp until
water saturation reaching to 25%. Calculate the oil volume inside the pore
at the end of flood
