OBJECTIVES To determine the prevalence of drug resistance and to analyze the subtyping in HIV-1 samples from Cuba. METHODS From an estimated total number of 1,950 HIV-1-infected persons in Cuba, a sample of 103 patients were studied, 76 of whom had received drug treatment for HIV and 27 who had not. The RNA plasma viral load was measured, and automated sequencing was used to assess resistance...

The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance models and the associated AASHTOWare® Pavement ME Design software are nationally calibrated using design inputs and distress data largely from the national Long-Term Pavement Performance (LTPP). Further calibration and validation studies are necessary for local highway agencies’ implementation by taking into acc...

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...

Reclaimed asphalt pavement is used as an aggregate in the cold recycling of asphalt paving mixtures. The more common method involves a process in which the asphalt pavement is recycled in-place (cold in-place recycling), CIPR. Where the Journal of Engineering Research (University of Tripoli) Issue (20) September 2014 67 reclaimed asphalt pavement is combined without heat with foamed bitumen and...

Cracking is one of the primary distresses for asphalt pavements. There are many types laboratory tests developed to evaluate cracking performance material, however, relatively little attention has been dedicated evaluating and correlating measured properties with actual pavement performance. The main objective this study investigate relationships between various binder/mixture (including both f...

A racionalidade limitada dos indivíduos pode influenciar à eficiência de títulos, conforme Hipótese Mercados Adaptativos (HMA). Esta pesquisa tem como objetivo verificar quais aspectos culturais/comportamentais influenciam o nível ineficiência mercados capitais internacionais. foi mensurada pelo Expoente Hurst, baseado nos indicadores médios desempenho acionários 44 economias. Os foram obtidos ...

Scrap tire rubber and nylon fiber are waste materials that could potentially be recycled used to improve the mechanical properties of asphalt pavement. The objective this research was investigate scrap (R-F) modified warm mix mixture (WMA). high-temperature performance estimated by Hamburg wheel-tracking testing (HWTT) device. low-temperature cracking evaluated disk-shaped compact tension (DCT)...

Fatigue characteristics of asphalt binder have an important role in asphalt mix resistance against cracking. Viscoelastic Continuum Damage (VECD) analysis of asphalt binders has been successfully used in highway research works in order to predict fatigue behavior of hot mix asphalt (HMA). In this method an intrinsic property of the material, called damage function is obtained which is independe...

Recycled aggregate pavement in bituminous can be repercussion to mitigation the exhaustion of rudimentary and asphalt, orientation alleviation quantities tailings organized into garbage dumps. This research aimed investigate performance Hot Mix Asphalt (HMA) surface with recycled concrete (RCA) as a replacement natural aggregates (NA) four substitution rates (0, 20, 40, 60) % from coarse aggreg...
