Moisture damage to bituminous pavement occurs via several mechanisms, and appears in diverse forms such as blistering, stripping, and disaggregation. Blistering is a fulminating phenomenon in which the trapped moisture evaporates and upheaves the pavement surface layer within a few hours as a result of so-called blistering heat. In contrast, stripping and disaggregation are types of internal ch...

Developing a responsive pavement-management infrastructure system is of paramount importance, accentuated by the quest for sustainability through adoption Road Traffic Management System. Technological advances have been witnessed in developed countries concerning development smart, sustainable transportation infrastructure. However, same cannot be said developing countries. In this study, pavem...

Pavement crack detection plays an important role in pavement maintaining and management. The threedimensional (3D) pavement crack detection technique based on laser is a recent trend due to its ability of discriminating dark areas, which are not caused by pavement distress such as tire marks, oil spills and shadows. In the field of 3D pavement crack detection, the most important thing is the ac...

After years of use, there’s oil loss on the asphalt pavement. bond strength aggregate decreases. Loose threshing is serious. In order to improve pavement performance, Extend service life pavement, Improve safety aircraft operation. We test AC-20 modified mixture taxiway and runway Chang Sha Airport from many factors, including raw materials, admixtures, gradation design, optimum ratio stone, th...

BACKGROUND Human settlements are of increasing interest to ecologists, a fact demonstrated by the recent cluster of book-length treatments of the topic (Forman 2008, McDonnell et al. 2009, Gaston 2010, Niemelä et al. 2011, Wilson 2011, Forman 2014). The natural world as a fascinating feature of towns and cities has a much longer history (e.g. Fitter 1945), and has also played a strong part in l...

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...
