The objective of this study is to compare the long-term aging performance dry-processed rubber-modified asphalt mixture with styrene–butadiene–styrene polymer-modified on heavy traffic volume roads in wet-freeze environment Michigan. rutting was evaluated using Hamburg wheel track device. disc-shaped compact tension test used assess fracture energy. dynamic modulus experiment estimate load and ...

Moisture damage and low-temperature cracking are common distresses experienced by road pavement. Different types of modifiers, such as fibers, can be used to improve the quality asphalt pavements. In this paper, lignin glass fiber were selected additives enhance water- stability mixtures. The main objective study was evaluate composite effects adding a bituminous mix using experimental methods....

In the present study, effects of adding fibers and Reclaimed Asphalt Pavement (RAP) on low temperature performances open graded asphalt mixtures for surface layer dense surface, binder, base layers were investigated. Two different kinds used: a combination aramid polyolefins utilized preparing fiber reinforced porous mixtures, while polyacrylonitrile employed producing conventional layers. Refe...

Abstract The use of recycled plastic in asphalt pavements represents a sustainable and economic choice which, if correctly designed, could significantly improve the resistance against typical distresses flexible pavements. For this reason, paper aims at evaluating mechanical properties two mixtures modified with plastomeric compounds through dry method, by comparing their results those obtained...

Traditionally, statistical techniques such as multivariate discriminant analysis and logistic regression analysis have been applied for predicting financial distresses by analyzing financial ratios. In addition to statistical methods, recent studies suggest that backpropagation neural networks (BPNs) and support vector machines (SVMs) can be alternative approaches for classification tasks. Henc...

Rutting, thermal cracking, and stripping are among the most severe distress types in asphalt pavement. In this study, a specified type of styrene-butadiene-styrene (SBS) was used as modifier for low viscosity binder G80/100 (PG 58-22) to overcome issues distresses mixture. The mixing process had been evaluated by using fluorescent microscopy. control- SBS-modified binders were subjected all con...

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...

The optimization of a pavement management system necessitates the knowledge on the actual values of pavement condition parameters, actual pavement condition improvement as related to the use of various rehabilitation strategies, and scope of pavement deterioration before and after rehabilitation. The data for six pavement condition parameters (bearing capacity, unevenness, rut depth, macro text...

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...
