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/...

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...

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...

This paper deals with the fundamental differences between industrial and paving-grade bituminous binders. The is presented in two main sections: 1) a review of materials’ colloidal structure required properties for paving applications; 2) wide range experimental tests which binders were studied compared. In this research, 160/220 bitumen was compared to same penetration lower penetration, 70/10...

Materials recycled with foam bitumen are promising materials for pavements economically and environmentally. However, there different opinions in the literature about how these positioned pavement. It is clear that their performances will not be suitable wearing course, but they used plant mixture base course because contain bitumen, neglected evaluation of materials. In study, 4 bituminous mix...

The incorporation of additives into bituminous mixes is a very important technique for improving the mechanical and electrical properties pavement body. purpose this work to present interpret different results tests carried out in laboratory; such as FENIX direct tensile test resistivity test. In work, we will comparative studies between characteristics based on conductive (steel fibers graphit...
