Polymeric Additives Effect on Mechanical Properties for Bitumen Based Composites [PDF]
Bitumen binder is a thermoplastic liquid and the elementary analysis of the bitumen manufactured from a variety of crude oils shows that most bitumen contains carbon, hydrogen, sulphur, oxygen, and nitrogen. At high temperature or low loading, it behaves

Study of the zero shear viscosity of SBS copolymer modified bitumens
The paper presents the results of the zero shear viscosity (ZSV) determined by using a dynamic shear rheometer (DSR). The tests were conducted with the use of 50/70 penetration grade bitumen produced from Venezuelan and Russian crude oils (named V50/70 ...

Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.

A novel multiphase composite was developed to prevent premature failure of waterproofing layers in pig houses. The system, comprising polyurethane, asphalt, and calcium carbonate, achieves a 1.35 MPa bonding strength and resists corrosion via a synergistic crosslinking, buffering, and passivation mechanism.

Moisture damage resistance of hot-mix asphalt made with recycled concrete aggregates and crumb rubber [PDF]
[Abstract:] To guarantee sustainable construction, we investigated the reuse of construction and demolition waste (CDW) as recycled concrete aggregate (RCA) for the manufacture of hot-mix asphalt (HMA) in place of natural aggregates.

ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...
