Distinguish between hot mix asphalt patching and crack seal used for the maintenance treatment for flexible pavements.

A small catchment has an area of 680 ha and consist of Type-C soil. The land cover is 40% open space_good condition, 15% commercial and business area, 30% residential and 15% roads/paved area. Assuming normal moisture conditions, determine the volume of direct runoff from a design storm of total rainfall of 200 mm from this catchment. What would be value of runoff volumes if the past 5 day total rainfall were 10 mm and 70 mm, respectively, assuming growing season in catchment?

You are the city manager of a medium sized city in a rural area, around a population of 20,000. Your city applied for and received a grant from an organization that will allow you to develop a system of systems approach to the regional solid waste issues. What would be your approach? Look at how you could improve recycling, gain energy from the collected resources, reduce the amount of material sequestered into a landfill, and what would you do with items such as tires and e-waste. Your goal is to be creative yet efficient and maybe even break even on costs.

So, this week we are looking at how to govern the fragmented metropolis. The metropolitan battleground is fragmented along the space, race and ethnicity lines in both the cities and suburbs. How relevant is the State's input in metropolitan governance? Along the same line, walling off the suburbs by creating gated communities leads to spatial inequity in development. What are some ways central cities can gain some back some of this urban economic power?

, and spread of violence affected the situation of blacks in the New South.

Breyer 4.32. Determine the ASD reference and adjusted design values for the following members and loading conditions. All members are Select Structural Southern Pine and are fully braced to prevent lateral-torsional buckling. Bending occurs about the strong axis.

Roof joists are 2x6 at 24 in. o.c. which directly support the roof sheathing. Loads are (D + S)

Floor beams are 4 x10 at 4 ft o.c. Loads are (D + 0.75(L + 0.6W)).

Design a RC wall of 4.6m height to support a factored load of 650 KN/m and factored moment of 30 KNm at right angles to the length of wall. The distance between cross wall is 4m. Sketch the reinforcement details.

Let's say you bought a plywood 2.5 m wide and 2 m long and placed it on the roof of your car.
The boundary layer formed when driving the car towards the house is laminar along the plate and the air flow of the plate
It is assumed that it is aligned in parallel. The boundary layer thickness at the end of the plate (escape edge) is 12.5 mm
by;
a) Local speed at the point of the plate (x, y) = (0.5 m, 2.5 mm), u
b) Local shear stress of the plate at the point (x, y) = (0,5 m, 2,5 mm), τx (Pa)
c) Find the total drag force on the plate, D (ρ air = 1.2 kg / m3, ν = 1.510-5 m2 / s).
