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...

This paper presents a fuzzy-based system that is used for maintenance planning of road pavements. The system has been developed based on knowledge elicitation from experienced maintenance engineers using fuzzy logic. The system includes functions for pavement condition and deterioration prediction, feasible treatment assessment in each pavement section, and maintenance planning in a road networ...

This paper proposes the use of neural network(NN-) based pavement structural analysis tools as surrogates for the flexible pavement response analysis in the new mechanistic empirical pavement design guide (MEPDG) developed for the American State Highway and Transportation Officials (AASHTO). Some of the recent successful applications of NN-based structural analysis models for predicting critica...

A critical issue concerning the deterioration of ageing road infrastructure all around the world is the need to rapidly and cost-effectively evaluate the present condition of pavement infrastructure. Non-Destructive Test (NDT) and evaluation methods are well-suited for characterizing materials and determining structural integrity of pavement systems. The Falling Weight Deflectometer (FWD) is a ...

In-service pavement requires maintenance, it may be routine in nature, or major reconstruction. A is designed for an assumed period, after the expiry of design likely to fail structurally and therefore, would require a renewal extend life further. Even within service pavement, top wearing course subjected considerable distress due movement vehicles on it. Thus needs some Maintenance smooth move...

This study aims to improve the accuracy of AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance predictions for Iowa pavement systems through local calibration of MEPDG prediction models. A total of 130 representative pavement sites across Iowa were selected. The selected pavement sites represent flexible, rigid, and composite pavement systems throughout Iowa. The req...

Road pavement maintenance today relies mainly on manual pavement condition inspection and distress rating; however, this manual method is costly, labour-intensive, time-consuming, and dangerous to inspectors and may affect traffic flows. Moreover, such method is very subjective and may have a high degree of variability, being unable to provide meaningful information. Additionally, since using t...

Pavement conditions could be degraded throughout its service life. Hence, a pavement management system is needed to ensure performance according design To support reliable pavement, condition survey needs conducted most effective and practical way. One of the technologies used in surveys Unmanned Aerial Vehicle (UAV) or known as drone. The use UAVs for road maintenance will reduce cost time wit...

Conventional flexible pavements built on lime stabilized soils (CFP-LSS) were studied for the backcalculation of pavement layer moduli from nondestructive Falling Weight Deflectometer (FWD) testing. The validated ILLI-PAVE finite element program was used in pavement structural analyses by taking into account the effects of nonlinear layer modulus behavior, i.e., stress hardening for granular ma...
