The conditions of airport movement-area pavements play a primary role on safety and regularity operations; for this reason, the aerodrome operator needs to periodically survey their condition provide maintenance rehabilitation in order ensure required operational characteristics. To meet these efficiently effectively, Airport Pavement-Management System (APMS) has proved be strategic tool suppor...

One of the most important components pavement management systems is predicting deterioration network through performance models. The accuracy prediction model for prioritizing maintenance action. This paper describes how models can have an effect on decision-making process in terms cost and rehabilitation activities. simulating propagation error between actual predicted values indicators. Diffe...

This paper describes the use of data mining tools for predicting the non-linear layer moduli of asphalt road pavement structures based on the deflection profiles obtained from non-destructive deflection testing. The deflected shape of the pavement under vehicular loading is predominantly a function of the thickness of the pavement layers, the moduli of individual layers, and the magnitude of th...

pavement design using mechanistic-empirical methods is often carried out based on the some assumptions for pavement layer's properties (thickness, elastic modulus, poisson's ratio and ….), loading properties(axial weight, tire coordinates, number of repetitions and …) and also the failure mechanism for different materials. fulfillment of these assumptions for evolution of pavement performance d...

The vast amount of data generated by automated surface distress evaluation equipment far exceeds the storage capabilities of current digital data storage systems. A study using fractals is being carried out to alleviate the data storage problem, since fractal image compression offers the largest compression ratio of the available image compression algorithms. This paper discusses the use of fra...

Monitoring the road pavement is a challenging task. Authorities spend time and finances to monitor the state and quality of the road pavement. This paper investigate road surface monitoring with smartphones equipped with GPS and inertial sensors: accelerometer and gyroscope. In this study we describe the conducted experiments with data from the time domain, frequency domain and wavelet transfor...

During 1998 the New Zealand (NZ) RIMS Group (Road Information Management Systems) initiated Phase I of a national project titled “Implementation of Predictive Modelling for Road Management”. This representative group comprises members representing all levels of government in NZ including the funding agency. The project arose from the need to implement a credible system that would be used to pre...

Road pavements have considerable environmental burdens associated with their initial construction, maintenance and usage, which has led the pavement stakeholder community make congregate efforts to better understand and mitigate these negative effects. Life cycle assessment (LCA) is a versatile methodology to quantify the effect of decisions regarding the selection of resources and processes. H...
