A six lane divided highway is to be designed to replace an existing highway. The present AADT (both directions) of 6000 vehicles is expected to grow at 5% per year. Assume SN = 4 and pt = 2.5. The percent of traffic on the design lane is 45%. Determine the design ESAL if the design life is 20 years and the vehicle mix is:Passenger cars (4.44kN/axle) = 60%2-axle single unit trucks (22.2kN/axle) = 30%3-axle single unit trucks (31.11kN/axle) = 10%
An asphalt plant can produce 360 tph. A project requires paving individual 11 ½ ft lanes with a 2-in lift averaging 110 lb/sy-in. What average paver speed will match the plant production? The haul road limits are 15 tons per dump truck. How many trucks will be required if the total hauling cycle time is 55 min?

(a) As an engineer at Jabatan Kerja Raya (JKR) Kuala Lumpur Headquarters, you are given the task to design a flexible road for a highway project at Perak. List FIVE (5) parameters of road thickness design required according to Arahan Teknik Jalan (ATJ) 5/85 Amendment 2013.
A 25 km long, 8.001 km wide, 2-lane highway is to be paved with 6.00cm thick layer of asphalt.A fleet of 4 dump trucks are to be employed each with an empty mass of 22metric tons and a carrying capacity of 26 cubic metres. Asphalt with a density of 2.322g/m^3 will be used. Determine a) The number of dump truck loads required b) If it takes 4 hours for each truck to deliver a load, how long in day and hours will it take the trucks to deliver all the asphalt? C) The gross mass of each truck.
Discuss each of the following topics in 10 sentences only. 1.) The pros and cons of performing periodic pavement maintenance throughout a pavements lifespan. 2.) The pros and cons of performing periodic railway maintenance throughout a railway's lifespan.
An asphalt paving crew is used to pave a road 7,000 feet long. The road is 36 feet wide and the paving machine can pave a 12-foot-wide strip of road during each pass. The machine paves 12 lineal feet of 12-foot-wide road per minute. Two lifts of asphalt are needed to pave the road. After completing a pass, it takes the crew 10 minutes to turn the paving machine around and get ready for the next pass. The crew consists of a foreperson, seven operators, and a laborer. Using a system efficiency of 50 minutes per hour, determine the number of labor hours required to place 1 lineal foot of road 12 feet wide. a. Determine the number of passes. b. Determine travel time. c. Determine productivity rate

12. Soil compaction is important information to be controlled during the execution of geotechnical works. An example of problems caused by poor compaction of materials are permanent deformations such as those observed in the existing pavement between Corumbá and the ports of Santos (SP) and illustrated in Figure 1. In an article published on 02/03/2022 in the newspaper Correio do Estado (https://correiodoestado.com.br/cidades/excesso-de-peso-faz-da-br262-uma-rodovia-de-alto-risco/397089) states that "in this region, the base of the landfill is fragile due to account of the inappropriate material used when building the road in the 1980s. Inadequate compaction also caused erosion problems (Figure 2) on the wall built by the United States on the border with Mexico, as published on the official website of the United States Homeland Security at 01/30/2021 (https://www.dhs.gov/news/2021/04/30/dhs- announces-steps-protect-border-communities-wall-construction).
