High-Definition Field Texture Measurements for Predicting Pavement Friction

Considering a New Sample Unit Definition for Pavement Condition Index

One of the main components of pavement management system (PMS) is pavement evaluation. Several indices have been defined for the evaluation of existing pavement. The Pavement Condition Index (PCI) is a common index used for pavement evaluation. In order to calculate PCI, a significant volume of condition data -based on distress surveying- is required. The objective of this research is to reduce...

Measuring and Analyzing Pavement Texture Concrete Pavement Surface Characteristics Program

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...

High-Definition Texture Reconstruction for 3D Image-based Modelling

Image-based modeling is becoming increasingly popular as a means to create realistic 3D digital models of realworld objects. Applications range from games and e-commerce to virtual worlds and 3D printing. Most research in computer vision has concentrated on the precise reconstruction of geometry. However, in order to improve realism and enable use in professional production pipelines digital mo...

Evaluation of Pavement Surface Friction Treatments

evaluating the combined effects ofَ friction coefficient and texture depth of asphalt concrete pavement on freeway accidents

many studies have been conducted focusing on the effects of friction coefficient or texture depth on the highway accident risk. however, combined effects of these parameters have not been still addressed. in this research the interaction between friction coefficient, texture depth and accident rate in 30 freeway sections were examined. the accident data were gathered and an apparatus was design...
