In the pursuit of a sustainable environment, and facing threat continuous growth solid waste in Iraq, this study investigated impact using blowdown, carbon-sulfur byproduct material sulfur purification, as mineral filler on durability rutting resistance dense-graded asphalt mixtures Styrene-Butadiene-Styrene (SBS)-modified asphalt. Three different blowdown rates (4%, 5%, 6% by weight aggregate)...

With the strengthened regulation on the mandatory use of recycled aggregate, development of construction materials using recycled aggregate has recently increased. This study aimed to secure the performance of asphalt concrete mixture by developing recycled-modified asphalt using recycled basalt aggregate from the Jeju area. The strength of the basalt aggregate from the Jeju area used in this s...

Marshall-Olkin exponential distribution has been studied by Salah, et al. [11,12]. In this paper, we consider the analysis of the hybrid censored data when the life time distribution of the individuals item is a two-parameter Marshall-Olkin exponential distribution. We study the estimations of the shape (α) and scale (λ ) parameters of Marshall-Olkin exponential distribution based on Type-II hy...

The feasibility of using large rubber chunks from shredded tires as aggregates in coldmixes for road construction was investigated in this study. The research was directed toward development of a chunk rubber asphalt concrete mix design for low volume road construction using local aggregate, shredded tire rubber chunks and a cationic emulsion. A set of mixes using different combinations of chun...

The flexible pavement layers are very susceptible to damage due moisture or water. Excess on any of can cause before the designed lifetime. To improve quality layers, modifications asphalt mixtures required. This study aims compare performance asphaltic mixture that was constructed by using two different additives, which Wetbond-SP and Retona Blend natural aggregates. There were three tests con...

The activity of crystalline trypsin and the trypsin-like amidase activity and the activity of trypsin inhibitors in serum were measured fluorometically, with a-benzoyl--L-arginine--na phthylamide (BANA) as substrate. The method is simpler and more sensitive than the colorimetric method based on the Bratton-Marshall reaction. Serum of pancreatectomized dogs hydrolyzed BANA at a significant rate,...

The monopole creation operator proposed recently by Frohlich and Marchetti is investigated in the Abelian Higgs model with compact gauge field. We show numerically that the creation operator detects the condensation of monopoles in the presence of the dynamical matter field.

INTRODUCTION The euryhaline killifish Fundulus heteroclitus lives in estuaries and salt marshes on the eastern coast of North America. Killifish must dynamically regulate their ion balance because of routine fluctuations in salinity in their natural environment. This species can tolerate changes in salinity from freshwater to nearly four times seawater (Griffith, 1974), and have therefore been ...

Stone mastic asphalt (SMA) mix amended with sugarcane bagasse fibers (SBFs) as a stabilizer was investigated experimentally in the present study. The SBF content combination varied (0, 0.15%, 0.30%, 0.45% and 0.60%) to produce different mixtures. prepared mixtures were then assessed for properties, such Marshall stability, tensile strength, draindown, which are crucial performance of flexible/b...
