Remarks:
• The PSD provides a unique characteristic that can be used in multiple tire-pavement contact models and in estimating pavement skid resistance.
• Although MPD can provide general insights into the pavement texture, the non-uniqueness of the MPD value can lead to the same measurements on different surfaces with different texture and physical characteristics.
• Texture models need more development to reach practical solutions.
