- 3. You have been asked to design the pavement for an access highway to a major truck terminal. The design daily truck traffic consists of the following: 80 single axles at 22,500 lb each, 570 tandem axles at 25,000 lb each, 50 tandem axles at 39,000 lb each, and 80 triple axles at 48,050 lb each. The highway is to be designed with rigid pavement having a modulus of rupture of 600 lb/in? and a modulus of elasticity of 5 million lb/in. The reliability is to be 95%, the overall standard deviation is 0.4, the drainage coefficient is 0.9, APSI is 1.7 (with a TSI of 2.5). and the load transfer coefficient is 3.2. The modulus of subgrade reaction is 200 lb/in'. If a 20-year design life is to be used, determine the required slab thickness.Q1) If the traffic using the pavement grows at an annual rate of 4 present ,determine the design ESAL for 20 years, if ESAL for one year =78900?You have been asked to design the pavement for an access highway to a major truck terminal. The design daily truck traffic consists of the following: 80 single axles at 22,500 lb each, 570 tandem axles at 25,000 lb each, 50 tandem axles at 39,000 lb each, and 80 triple axles at 48,000 lb each. The highway is to be designed with rigid pavement having a modulus of rupture of 600 lb/in2 and a modulus of elasticity of 5 million lb/in2. The reliability is to be 95%, the overall standard deviation is 0.4, the drainage coefficient is 0.9, ΔPSI is 1.7 (with a TSI of 2.5), and the load transfer coefficient is 3.2. The modulus of subgrade reaction is 200 lb/in3. If a 20-year design life is to be used, determine the required slab thickness.
- From the traffic counting in 2020, the average commercial vehicle per day is 500 (10% commercial vehicle) and the traffic growth rate is estimated at 5%. A pavement needs to be designed for 15 years and is expected to open for the public in 2022. Using ATJ 5/85 method, estimate the total number of vehicles per direction during the first year of service. * 100740 213669 O 1108240 O 2173824Calculate ESAL in the design lane for 20 year design period for asphalt (assume TSI= 2.5) and concrete (assume TSI= 2.5 and D = 9 inch) pavement, respectively, based on the initial traffic of single axle-loads shown below, given that the yearly rate of growth 2%, Direction Distribution Factor -50%, Lane Distribution Factor = 75% Axle Load Number (kip) 18 20 22 24 26 28 30 32 34 per day 61.4 47.2 21.4 12.9 6.1 2.9 1.2 0.7 0.3Design is required for a new pavement to be constructed in 2010. The annual average daily traffic for commercial vehicles on the opening day will be 2000. Growth rate = 4% Design Life = 20 years Solve for the design traffic in msa using 2 decimal places.
- 4.7.6 Design an asphaltic concrete pavement thickness using Arahan Teknik Jalan 5/85, Arahan Teknik Jalan 5/85 (Pindaan 2013) and Road Note 31 methods based on these data: Average commercial vehicle per day per direction (2016) = 1600 (which is 30 %of total traffic per day per direction) Traffic growth rate per year = 6.0% SEX ● ● Design life = 10 years Thickness and CBR value for subgrade layers: 350 mm (12%), 350 mm (8%) and 300 mm (4%) Project is expected to complete and open to traffic in 2019. Compare the thickness obtained and comments.Assume the OPI of non-interstate highways in the district is 70. The total lane-miles of interstate in this district are 500 miles while the total line-miles of non-interstate highways are 3,500 miles. What is the OPI of all pavements in the district?I need all the parts otherwise skip, it's my first question on bartleby if I liked I'll purchase more so pls do it nicely so that I can buy again
- The AADTT of a 2-way (2-lane each way) highway is 10,000. The directional distribution may vary between 45 and 55% depending on season. The lane distribution may vary between 60 and 75%. The driving lane always carries more loads compared to the passing lane. The growth factor for the pavement is 3.5%. Based on the above information, calculate the design AADTT for the driving lane if the pavement service life is 20 years.A highway is projected to carry 16,000 vehicles per day (10% of which will be 3-axle trucks with an axle load equivalency factor of 0.088) upon opening and 4% growth rate over the next 25 years. If an estimated 40% of traffic is to be in the design lane, the number of ESALS to be used in pavement design is: O 1.84 x 106 O 2.57 x 106 O 2.57 x 107 O 8.57 x 105 O 6.42 x 106Take a look at the many techniques available for assessing the quality of bitumen used in flexible pavements. The topic of transportation engineering is covered.
