Cross-linked polyethylene (XLPE) is an appropriate insulating material for high-voltage cables which has been widely used as electrical cable coating. In this study, Crushed XLPE wastes with different volume percentages (25, 50, and 75%) were used in hot mix asphalt (HMA) as a substitute for fine aggregates remained on sieve no. 8 whose size varies from 1.18 to 2.36 mm. The dynamic stiffness (i...

Resilient modulus of pavement materials is a key property required for the pavement thickness design. This paper describes the results of an experimental study on the effects of temperature and loading frequency on the resilient modulus of a SBS polymer modified asphalt concrete under dry and saturated conditions. Dynamic creep tests were conducted on dry and saturated specimens of the mixture ...

Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...

This paper examines the travel behavior of the Chinese and Korean tourism market following the Japan Earthquake in a bid to identify travelers who are likely to be most and least resilient in the event of a significant disaster. The post disaster travel behavior of travelers from these two countries is analyzed to reveal the circumstances under which travelers would go to Japan despite the eart...

PROBLEM STATEMENT When designing and evaluating asphalt pavements, engineers must have an understanding of how the pavement materials will react to the stresses and strains of vehicle loads at varying temperatures. When a load is applied to asphalt concrete at a certain temperature, to what degree will the pavement "bounce back" to its original height? Pavement designers predict this spring-lik...

BACKGROUND Children of alcoholics (COAs) are at elevated risk for alcohol use disorders (AUD), yet not all COAs will develop AUD. The 2 primary aims of this study were to identify neural activation mechanisms that may mark protection or vulnerability to AUD in COAs and to map the same activation patterns in relation to risk behavior (externalizing or internalizing behavior). METHODS Twenty-tw...
