Pavement crack is the main form of early diseases of pavement. The use of digital photography to record pavement images and subsequent crack detection and classification has undergone continuous improvements over the past decade. Digital image processing has been applied to detect the pavement crack for its advantages of large amount of information and auto detection. The application of digital...

Pavement condition evaluation is a significant part of a good pavement management system for effective maintenance, rehabilitation, and reconstruction decision-making. One of the key components of pavement condition evaluation is the quantification of pavement distresses data. Cracking is the main form of early pavement distresses. Cracking of pavement affects road condition, driving comfort, t...

Pavement distresses (damages) are important information for evaluating the road condition and conducting the necessary road maintenance activities. Conventional human visual pavement distress detection method is time consuming, very expensive, labour-intensive and dangerous due to exposure to traffic. Numbers of methods have been introduced for road damage detection in the context of fine struc...

Many agencies use the AASHTO Guide for Design of Pavement Structures to design their pavement systems. The limitation inherent in this method is the empirical nature of the decision process, which was derived from a road test conducted almost 45 years ago in Ottawa, Illinois. The newly released Mechanistic-Empirical Pavement Design Guide (MEPDG), based on NCHRP Study 1-37A, has adopted a mechan...

With the advancement of 3D line laser imaging technology (“3D technology”, hereafter for the sake of brevity), high-resolution 3D transverse profile data (“3D data”, hereafter for the sake of brevity), has gained widespread interest from researchers, industry and highway agencies and has been used for collecting pavement surface distresses. However, the study of data characteristics, e.g. data ...

this paper identifies eleven types of asphalt pavement distress types, commonly occuring in tehran metropolitan area. of these, five distresses namely: corrugation; utility cut depression ;pot holes; alligator cracking; and loss of bridge deck surfacing are rather common. however, others namely: shear failure; shrinkage cracks; lane joint cracks; bleeding; and shoulder distress are less prevail...

Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement, exposing themselves to hazardous conditio...

As one type of pavement distresses, potholes are important clues indicating structural defects of the asphalt road, and accurately detecting these potholes is one of important tasks for determining proper strategies of asphalt-surfaced pavement maintenance and rehabilitation. However, manually detecting and evaluating methods are expensive and timeconsuming. Thus, several efforts have been made...

A pavement structure consists of several layers for the primary purpose of transmitting and distributing traffic loads to the subgrade. Rutting is one form of pavement distresses that may influence the performance of road pavements. Geosynthetics is one type of synthetic materials utilized for improving the performance of pavements against rutting. Various studies have been conducted on using d...
