Based on the analysis of several asphalt mixtures in Indonesia, generally, asphalt mixture has stiffness modulus (E<SUB>1</SUB>) varies from 2000 MPa to 5000 MPa. At the subgrade layer, soil has CBR value at 3% to 6% which is equivalent to modulus (E<SUB>3</SUB>) at 30 MPa to 60 MPa. The second layer would be a base layer with thickness considered to be a constant value at 200 mm and stiffness modulus (E<SUB>2</SUB>) at 100 MPa. The other characteristic is Poisson's Ratio (ν). Poisson's Ratio for surface (ν<SUB>1</SUB>), base (ν<SUB>2</SUB>) and subgrade (ν<SUB>3</SUB>) was taken as 0.35; 0.40; and 0.45 respectively. Considering the material characteristic above then design nomograph were developed. The nomographs were inspired by Nothingham and there are then 4 types of nomographs related to a subgrade modulus. Pavement thickness result designed using mechanistic procedure was thicker than empirical method.
