Nowadays, the increasing amount of wastes is a concerning reality and the environmental aspects has become a major priority. Following this worry, the purpose of this experimental study was to investigate the possibility of using pulp and paper inorganic wastes, named dregs and grits, in bituminous mixtures as aggregate replacement to reduce environmental effects of these wastes disposal. First...
Three hundred and five coal samples were taken from the main coal mines of twenty-six provinces, autonomous regions, and municipalities of China. The method of pyrohydrolysis was applied to measure the fluorine content in the samples, which exhibit logarithmic normal frequency distributions. The range of fluorine content in dry coal varies from 25 to 1230 mg/ kg with a geometric mean of 136 mg/...
This paper addresses scenarios of integrated satellite-terrestrial Future Internet networks based on the Information-Centric Networking (ICN) communication paradigm. Focus is given on three integration scenarios: i) Hybrid Broadcast IPTV, paving the way for SatCom integration within the Future Media Internet; ii) Smart M2M Transport, paving the way for SatCom integration within a future Interne...
blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...
• Concurrent use of RA, Stabilized Bottom Ashes and Waste Engine Oil is investigated. Compaction Energy Index was successfully used to assess compaction characteristics. High contents RA were for bituminous wearing courses. can be as a fluxing agent, reducing aged binder viscosity. artificial aggregates. Reduce, recycle reuse materials are the three crucial procedures that affect economy curren...
We prove some new equivalences of the paving conjecture and obtain some estimates on the paving constants. In addition we give a new family of counterexamples to one of the Akemann-Anderson conjectures.
The construction sector is one of the most demanding sectors for materials that exist today. Therefore, in order to avoid extraction new raw materials, it necessary use waste. This waste must present a series physical and chemical characteristics make suitable its employment. this investigation, ladle furnace slag characterized as filler bituminous mixtures. These slags are produced by metallur...
Background and Objective: COVID-19 was first seen in Wuhan-China in December 2019, and became a widely- spreadepidemic and caused a terrifying life-threatening problem in most societies of the world. In Iran, a declaration was made on January 20, 2020, and all health systems were alerted of the disease threats. Materials and Methods: We collected all chest CT scans of 200 cases diagnosed as C...
