The development of UV-shielding materials has attracted considerable attention in the field of coatings and sunscreen. This paper reports the UV-shielding mechanism of layered double hydroxide (LDH) materials in terms of chemical composition, structure and morphology, by using (LDH/PAA)n films (n stands for bilayer number) through alternate LBL assembly of LDH nanoparticles and poly(acrylic aci...

In this data article experimental data on the compressive strength, and the durability of styrene and bitumen modified sulfur concrete against acidic water and ignition are presented. The percent of the sulfur cement and the gradation of the aggregates used are according to the ACI 548.2R-93 and ASTM 3515 respectively. For the styrene modified sulfur concrete different percentages of styrene ar...

-In hot countries like India roads laid on agricultural zones and other water prone areas will be affected by severed pot holes created due to the water entry in the pavement. Increase in road traffic in combination with insufficient maintenance due to shortage in funds causes rapid deterioration of the roads. To lighten this process, several measures may be effective, such as, use of better qu...

Road construction takes a heavy toll on the environment. Therefore, innovative strategies to improve environmental performances of this sector are needed, and use recycled materials (e.g., plastic) has been recently pursued achieve goal. The present work aims (i) assess benefits deriving from hard plastics in combination with graphene generate new bitumen modifier related asphalt mixture (AM) f...

modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. this paper present the effect of there novel modifier as precipitated calcium carbonate (pcc) and two type of nanoclay on rheological properties of bitumen binder. various blends of modifier and bitumen were selected and...

Environment conservation and diminishing natural resources caused an increase in popularity of the application of renewable bio-origin resources for the construction of road pavement. Currently, there are known additions of bio-origin materials for bitumen modification. Such material is also used as a flux additive for bitumen or as a rejuvenator once working with reclaimed asphalt pavement (RA...

The increasing environmental concern about waste materials and the necessity of improving the performance of asphalt mixtures prompted the study of incorporating different waste materials in conventional bitumen. The reuse of waste materials can present benefits at an environmental and economic level, and some wastes can be used to improve the pavement performance. Thus, the purpose of this stu...

Aiming to quantitatively evaluate the microstructure of polymer-modified bitumen (PMB) for roads, this paper employs the two-dimensional fast Fourier transform (2DFFT) to process the microscopic and numerical images of four PMBs. The related derivative parameters, including the characteristic frequency and wavelength, are computed from the 2D-FFT power spectrum. The results show that the absenc...

This study aims to investigate the effect and possibility of using waste plastic as a sustainable cost-effective polymer modify bitumen binders. Different types have been used in this modification, including polyethylene terephthalate (PET), high-density (HDPE), low-density (LDPE). The modification targets physical characteristics, rheological properties, binders’ resistance ageing. Both long- ...

In this study, different contents of Nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen to modify the physical, mechanical and rheological properties of warm mix asphalt (WMA). WMA is containing 2 wt.% of Sasobit (mixture of long-chain hydrocarbons). Various quality control tests have been carried out to characterize the modified bitumen and WMA. The rheo...
