In addition to lower emissions warm mix asphalt has several advantages over hot mix asphalt such as fuel energy savings, decreased binder aging and an extended paving season (Photo courtesy: Matthew Corrigan, FHWA) The National Center for Asphalt Technology (NCAT) is evaluating warm mix asphalt (WMA) technologies. WMA technology allows the mixing, lay down, and compaction of asphalt mixes at si...

Despite the emergence of a number of new classification systems, the diagnosis of cerebrovascular dementia remains controversial. Also controversial is the significance of periventricular and deep white matter alterations (WMA) as seen on magnetic resonance imaging (MRI). To further clarify this issue, MRI scans were used to regroup patients clinically diagnosed with Alzheimer's disease (AD) or...

In this paper, the effect of combined use re-recycled Reclaimed Asphalt Pavement (RAP) on performance properties Warm Mix (WMA) was experimentally investigated at both binder and mixture scales. First, a virgin 50/70 Pen Grade fresh Gabbro aggregates were used to prepare conventional Hot (HMA) for surface layers as reference mixture. Then, same mix type produce designed with 40% RAP, 160/220 bi...

in this study, different contents of nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen tomodify the physical, mechanical and rheological properties of warm mix asphalt (wma). wma iscontaining 2 wt.% of sasobit (mixture of long-chain hydrocarbons). various quality control tests have beencarried out to characterize the modified bitumen and wma. the rheological investigations show...

Recently cell phones and personal digital assistants (PDAs) have become a popular medium for browsing the web. Entering a search term in these mediums, however, is significantly more difficult than typing at a full computer because of small keyboard and stylus interfaces. Also some individuals find it difficult to type due to injury or disability. For these reasons many search engines and brows...

Background Patients with ischemic cardiomyopathy (CMP) often develop regional wall motion abnormalities (WMA) due to myocardial scarring, stunning or hibernation. Abnormal functioning myocardial segments without evidence of fibrosis on late gadolinium-enhancement cardiac magnetic resonance (LGE-CMR) are felt to represent stunned or hibernating myocardium, presumably with significant coronary ar...

The medical crimes of the Hitler regime are commonly perceived to have been committed by a few demonic physicians working in isolation from the mainstream of the German medicine. The success of this myth has imperiled the value system of medicine today. The World Medical Association (WMA), established to address the ethical challenges arising from the German tragedy, has itself been compromised...

The objective of this study is to test the hypothesis that titanium dioxide (TiO2) can function as a photocatalytic compound when used in the preparation of warm-mix asphalt (WMA). The proposed asphalt mixture would combine the benefits of WMA such as reduced energy consumption and emission during production with the photocatalytic properties of TiO2 to trap and degrade organic and inorganic pa...

As a member of the Japan Medical Association Junior Doctors Network (JMA-JDN), I had the honor of participating in the World Medical Association (WMA) Council Session and JDN meeting held in Oslo, Norway, from April 16 through 18, 2015. I am grateful for the opportunity to report on these meetings. The WMA is an organization of 111 national medical associations (NMAs) representing physicians th...

For many years, the asphalt industry has been aware of the energy savings and environmental benefits inherent in cold mix or warm mix asphalt technologies. Environmental awareness and the need for improved energy efficiency has increased rapidly over the past few years and extensive measures such as the air pollution reduction targets set by the European Union under the Kyoto Protocol have enco...
