The assessment of the anti-skid properties airfield pavements is one elements in process determining their current technical condition, which important terms safety air operations. condition pavement should be qualified on basis specified and required values (criteria), this case, coefficient friction depth texture. Unfortunately, practice, texture new raises some doubts with regard to existing...

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 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 ...

We present a novel deep learning framework named the Iteratively Optimized Patch Label Inference Network (IOPLIN) for automatically detecting various pavement distresses that are not solely limited to specific ones, such as cracks and potholes. IOPLIN can be iteratively trained with only image label via Expectation-Maximization Inspired Distillation (EMIPLD) strategy, accomplish this task well ...

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...

Smart cities can be controlled in all aspects and it is desired to have a structure that planned controllable feedback. Asphalt generally used as pavement material on roads provide transportation of vehicles such cars buses the highway. deformed due weather conditions, heavy vehicle passage. In smart city structure, similar deformations should reported relevant unit. this article, was tried det...

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...
