Waste plastic pollution is a serious issue. In order to adhere the concept of green development and rationally dispose polyethylene waste products, (PE)-modified asphalt was prepared using recycled (RPE) low-density (LDPE) as raw materials. The chemical structures RPE- LDPE-modified were studied Fourier transform infrared spectrometer (FTIR), dispersion RPE fluorescence microscope (FM). Subsequ...

Additives are widely used to enhance the rheological and performance properties of asphalt binder satisfy demands extreme loading climatic conditions. Meanwhile, adding complexity behaviour that requires more time, effort, material resources during laboratory work. The purpose this research was use Artificial Neural Networks (ANNs) predict recovery (R) nonrecoverable compliance (Jnr) based on m...

Crumble rubber (CR) can be used to prepare CR and styrene-butadiene-styrene (SBS) composite modified asphalt with a good high-and low-temperature performance, meanwhile the addition of could work as substitute for SBS help reduce content SBS. This study contains three main parts: effect preparation material composition well rheological performance characterization. Factors during preparation, i...

In the road construction sector, CO2 emissions that affect global warming are, in most cases, from asphalt mixtures production activities are carried out at high temperature (above 160 °C). The research here presented aims to investigate physical-mechanical properties of mastics made up using jet grouting waste (JW) as a filler produced through both cold (40–50 °C) and hot mixing process. first...

This research study aims to investigate the feasibility of incorporating high-density polyethylene waste (HDPEW) into bitumen applications. Two conventional conditions bitumen, namely, aged (AB) and virgin (VB), are rejuvenated modified, respectively, using post-consumer HDPEW sourced out bottle crates. The outcome (Pyro oil, PO-HDPEW) pyrolysis thermochemical process is used by 10, 20, 30% rej...

The effect of aluminum oxide nanoparticles (Al2O3) on the 60/70 penetration asphalt cement (AC) was investigated in terms physical and rheological characteristics by using Superpave testing procedures. Al2O3 at 3, 5, 7% concentrations were blended with grade AC. Conventional procedures adopted regarding characteristics, while dynamic shear rheometer (DSR) conducted to evaluate high low temperat...

Conventional asphalt concrete pavements have deteriorated rapidly due to the current increased traffic and extreme climate impacts. In addition upgrading in construction quality, there is an urgent need expand utilization of modified binders improve road capacity safety. The proposed research aims combine epoxy resin (ER) crumb rubber powder (CRP) contents into conventional Styrene-butadiene-st...

Styrene-butadiene-styrene (SBS) is currently the most widely used asphalt modifier. However, high-SBS-concentration high-viscosity modified asphalts (HVMA) are characterized by poor flow and storage instability. To make up for lack of performance traditional SBS-HVMA, a nano-based composite with excellent was developed. Since carbon nanotubes (CNTs) nanomaterials, they prone to agglomeration wh...

A personal history of the development of molten-salt reactors in the United States is presented. The initial goal was an aircraft propulsion reactor, and a molten fluoride-fueled Aircraft Reactor Experiment was operated at Oak Ridge National Laboratory in 1954. In 1956, the objective shifted to civilian nuclear power, and reactor concepts were developed using a circulating UF4-ThF4 fuel, graphi...
