The definition of term pavement management and the three strategies to develop restoration and rehabilitation programs used by public agencies.

Explanation of Solution
Pavement management is a systematic method for maintaining, upgrading, and in operation physical pavement assets during a cost- efficient manner. The method combines applications of established engineering principles with theory of economic and sound business practices, therefore reassuring an organized and approach of scientific to decision making.
The term pavement management refers to the different kinds of strategies that may be used to choose a restoration of pavement and rehabilitation policy. At one end, there's the "squeaky wheel" approach, whereby projects are selected because they have created the highest attention.
At the other end, there is a system whereby roads of all are repaired on a regular schedule, for which there is no object of money.
The three strategies to develop restoration and rehabilitation programs used by public agencies are given below.
- Pavement rehabilitation or rehabilitation programsare plans that includes minimum standards for pavement acceptable condition and required to establish the type treatment which is required to maintain a minimum level of serviceability and the time frame for the completion of project.
- Rehabilitation program strategies include consideration of items such as condition of pavements, first cost, maintenance of annual, user costs, physical, safety, environmental, and economic factors which are external.
- Life-cycle cost analysis is the basis for management of pavement and having the total cost of the project, including construction at the initial stage, regular maintenance, and important rehabilitation activities over the pavement lifetime.

- Part 3: Problem-Solving. Solve the following problems. Show all calculations. 1. A retaining wall 5.80m high supports soil that has the following properties: Unit weight = 17.3 kN/m³ Angle of internal friction = 26 deg. Cohesion = 14.5 kPa a) Calculate the normal pressure acting at the back of the wall assuming no tensile crack occurs in the soil. b) Find the location of the tensile crack measured from the surface of horizontal backfill. c) Determine the active pressure acting on the wall in tensile crack occurs in the soil. 2. The soil material is supported by a retaining wall to a height of 6m. The unit weight of the soil is 16 kN/m³ and the angle of internal friction is 29 deg. Assume the soil is cohesionless. a) Determine the earth pressure on the wall. b) Find the total active pressure if surcharge of 14 kPa is applied on the surface of horizontal backfill. c) Locate the position of the total pressure from the bottom.arrow_forwardQuestion 3 (20 points): The traffic volume on a 2-lane highway is 1600 veh/hr in each direction Page 3 of 6 with a density of 20 veh/mi. A large dump truck enters the traffic stream from an adjacent construction site at 20 mph and carries on this way for 2 miles before turning off to the dump site. Because flow is so high in the opposite direction, no one can pass the truck. As a result, traffic back up behind the truck at four times the density (i.e., 4x20 = 80 veh/mi) at a volume of 1000 veh/hr. How many vehicles get caught in the traffic congestion before the truck exits the highway?arrow_forwardHow can construction project managers find a balance between speeding up schedules and the risks of making more mistakes and needing rework, especially when using methods like fast tracking?arrow_forward
- What are the total earned work hours at completion for the column forms?arrow_forward6000 units have been installed to date with 9,000 units to install. Labor costs are $23,300.00 to date. What is the unit cost for labor to date?arrow_forwardThe base rate for labor is $15/hr. The labor burden is 35% and 3% for small tools for the labor. There are 1000 units to install. Records indicate that trade workers can install 10 units per hour, per trade worker. The owners need 15% overhead and profit to pay bills, pay interest on loan and provide some profit to the partners. What is the minimum bid assuming no risk avoidance factor?arrow_forward
