Using the layered AASHTO pavement design method, determine which one of two pavement section options results in a lower cost. For both pavement sections, assume a MR-7500 psi for the existing ground . Assume a reliability of 95%, Standard Deviation (So) of 0.35, ESAL of 9.0x106 and serviceability loss to be 1.0 for both options. 5. Option 1: A two-layer pavement section with HMA and an granular base course. Option 2: A three layer pavement section with HMA, granular base,...

A new highway is to be constructed. Design A calls for a concrete pavement costing $80 per foot with a 16-year life;three paved ditches costing $4 per foot each; and two box culverts every mile, each costing $7,000 and having a 16-year life. Annual maintenance will cost $1,900 per mile; the culverts must be cleaned every four years at a cost of $450 each per mile.Design B calls for a bituminous pavement costing $50 per foot with a 8-year life;...
