color: #000000;\">The research presents the development of a <strong>Laser MPD: DRR prototype device<\/strong> for measuring <strong>Mean Profile Depth (MPD)<\/strong>, a characteristic of pavement macro-texture that is related to pavement friction.<\/span><\/p><p><span style=\"font-size: 12pt; color: #000000;\">The prototype was developed based on <strong>ASTM E1845<\/strong>, and the study examined the relationship between MPD and the coefficient of pavement friction. The results indicated that <strong>when MPD was higher than 1.5 millimeters, the coefficients of pavement friction of the investigated pavement samples were higher than the investigative level of 0.35<\/strong>.<\/span><\/p><p><span style=\"font-size: 12pt; color: #000000;\">The study therefore proposed using MPD as a <strong>screening threshold for road sections<\/strong> to reduce the need for direct friction measurements across all pavement sections, particularly at the investigative level. This can help reduce the time and cost of data collection for pavement friction management and road safety
