Subject: Transportation Engineering  An asphalt pavement carries a static wheel load of 125 kN. The circular contact radius of the tire is 180 mm and the transmitted load is distributed across a wide area of subgrade at an angle of 47°. The subgrade bearing value is 0.30 MPa while that of the base is 0.60 MPa. Design the thickness of the pavement and that of the base ?  Please give me right solution.. urgenttttttttt help me  Thank you
Design a pavement for a rural interstate highway. The expected design ESAL is 13x106. The pavement structure is to consist of asphalt concrete with an elastic modulus of 400000psi, a granular base with an elastic modulus of 26000psi, and a granular subbase with an elastic modulus of 12000psi. The elastic modulus of the subgrade is 8000psi. It is estimated that it will take a week for water to drain from the pavement and that the pavement will be saturated about 15% of the time. Assume that a reliability level o about 90% is required and that the initial serviceability index is 4.2 and the final serviceability index is 2.5.
Please kindly answer both.. please give me both answers
