- 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 0.3An asphalt plant can produce 306 tons per hour.

- 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 106Please solve fastRoad engineering
- A pavement has a design life of 20 years and design traffic of 75 msa for a newly developing National Highway. Number of commercial vehicles after construction of pavement is 4200 vehicles per day. If vehicle damage factor is taken as 1.05 and annual rate of traffic growth is taken as 8%, then the value of lane distribution factor adopted is. (Round off to two decimal places).A northbound direction on an interstate highway consists of three lanes of flexible pavement. The subgrade CBR is 4.5, the overall standard deviation is 0.38, and the reliability is 95%. The initial PSI is 4.5 and the final PSI is 2.5. Daily total northbound road traffic consists of 39,500 cars (each with two 2kip single axles), 775 buses ((each with two 19 kip single axles) and 1100 heavy trucks (each with two 10kip single axle and two 34kip tandem axles). If the pavement is designed to last for 20 years, what should be its structural number?Round your answer to 1 decimal place.

A project requires paving individual 10-ft lanes with a 12 in. lift averaging 115 lb/sy-in. What average paver speed will match the plant production? How many 20-ton dump trucks will be required if the total hauling cycle time is 40 min?The traffic projection for a new pavement of a two-lane rural dual carriageway is as follows: Design period = 25 years AADT in current year = 5000 vehicles per day Direction factor = 0.5 Percent of heavy vehicles = 6% Annual traffic growth = 6% Damage index: ESA/HVAG = 0.75; SAR5/HVAG = 0.95; SAR7/HVAG = 1.65; SAR12/HVAG = 19.65. %3D %3D Table 2 Traffic load distribution Load (kN) SAST SADT TAST TADT TRDT 70 0.21 0.12 0.31 0.18 0.21 80 0.34 0.29 0.21 0.48 0.41 90 0.45 0.59 0.48 0.34 0.38 Proportion of each axle group 0.136 0.294 0.315 0.103 0.152 a) Calculate the average number of axle groups per heavy vehicle NHvaG Using the data in the Table. b) Calculate the design traffic in HVAG (NDT). c) Calculate the design traffic in ESA, SAR5, SAR7 and SAR12.
