A combination inlet consists of a 3-m long curb inlet and a 0.6 m by 1.2 m reticuline grate inlet adjacent to the downstream 1.2 m of the curb opening. The gutter section has a width of 0.6 m, a longitudinal slope of 1.5%, a cross slope of 3.5%, and a gutter depression of 30 mm. The roadway pavement consists of rough asphalt. For a flow rate of 0.0.9 m³/s in the gutter, calculate the interception capacity of the inlet.

11.3. A roadway has a flow depth at the curb of 9 cm and a corresponding flow rate in the gutter of 0.1 m³/s. If the gutter flow is to be removed in a vertical sag by a 15-cm- high curb inlet, determine the minimum required length of the inlet. Consider the cases where: (a) the width of the inlet depression is 0.3 m, and (b) there is no inlet depression.
On a railroad, a -0.8% grade meets a +0.4% grade at Sta. 2 + 700 whose elevation is 30 m. The maximum allowable change in grade per station having a length of 20 m is 0.15 %. It is desired to place a culvert to draw the waters during heavy downpour. Where must this culvert be located? At what elevation must the invert of the culvert be set if the pipe has a diameter of 0.9 m and the backfill is 0.3 m high. Neglect the thickness of the pipe. Please show the detailed solution. Thank you

Water flows in a 20000-m long smooth-asphalt trapezoidal channel at 55 m³/s with side slope of 2.5(H):1(V). Elevations at the beginning and end of channel are 400 m and 376 m, respectively. Analyse its efficient-channel section. (d)
Question- At an industrial area an access road to an industrial facility is paved with a 3 Sand-mix asphaltic concrete wearing layer, a 5 Hot-mix asphaltic concrete base layer, a crushed stone subbase layer and has a structural number of 4. Assume that the drainage coefficient for the base layer is 1 and the drainage coefficient for the subbase layer is 0.94. The access road is designed for a maximum traffic load of 9x106 ESAL for 25-years design period. Find the thickness of its subbase layer of crushed stones used in this pavement.
A flexible pavement has the following class of loads during a particular hour of the day. i. 80 buses with 2-axles (each axle load of 40 KN); ii. 160 trucks with 2-axles (front and rear axle loads of 40 kN and 80 kN, respectively) The equivalent standard axle load repetitions for this vehicle combination as per IRC: 37-2012 would be
