The non-segregated area texture depth can be predicted using various properties of the original job-mix formula.Two models for predicting non-segregated area texture depth were developed.The models are verified by the results of field and laboratory tests,indicating that the models are inadequate for the wide range of mix types.A new model is developed to relate fine modulus,the nominal maximum aggregate size,percentage passing the 4.75 mm sieve and asphalt content.The model yields a good estimate of the mixes including SMA-16 and AC-20 mixes.
