Quality Assurance for Chip Seals Using Mean Profile Depth
… through various parameters, including texture depth, skid resistance, and visual evaluation. Current practice reveals that transportation agencies conduct quality assurance after construction, while contractors are typically responsible for chip seal placement and quality control. However, …

Evaluation of the Repeatability and Reproducibility of Network-Level Pavement Macrotexture Measuring Devices
… and validated the reproducibility of the mean profile depth (MPD) measurements with reference CT Meter measurements. The various data sets were then compared with each other. The objective was to determine whether the two systems are collecting repeatable and reproducible data. The …

Enhancement of Network Level Macrotexture Measurement Practices through Deterioration Modeling and Comparison of Measurement Devices for Integration into Pavement Management Systems
… that, on average, the macrotexture's root mean square (RMS) decreased 0.14 mm per million equivalent single axle load applied. A comparison of RMS and mean profile depth (MPD) outputs indicated that RMS was more sensitive to changes in macrotexture due to bleeding. In comparing devices, …

Comparison of Macrotexture Measuring Devices Used in Virginia
… laser-based devices: MGPS system, ICC laser profiler, and Circular Texture Meter (CTMeter). The study used data from three sources: two controlled experiments conducted at the Virginia Smart Road, field data collected on eight newly constructed hot-mix-asphalt (HMA) roadway surfaces, and data …

Quantifying the Impact of Pavement Surface Properties on Road Safety: A Data-Driven Approach
… Number at 40 mph (SFN40), Macrotexture via Mean Profile Depth (MPD), and pavement age and classification, there incremental value within SPFs remain under quantified. This gap leaves agencies uncertain about surface measures materially improving prediction and how large their effects are in …

Enhancing Pavement Surface Macrotexture Characterization
… coefficients (without outliers) to obtain the Mean Profile Depth (MPD) from the measurements with the spikes removed. The method was validated by comparing the results with MPD measurements obtained with a Circular Texture Meter (CTMeter) that was chosen as the control device. Although this …
