The structural layer coefficients sand sub-base, crush stone base and hot-mix asphalt are 0.10, 0.15, and 0.41. The drainage coefficients for sub-base and base are 0.9 and 1.0, respectively. Based on AASHTO 1993 Pavement Design Guide, for the hot-mix asphalt to provide a structural number of 2.6 to protect the base course (stone), what is minimum thickness needed for hot-mix asphalt layer (inches)?
