Effect of filler nature and content on the bituminous mastic behaviour under cyclic loads [PDF]
, 2017 The role of the filler in asphalt mixtures is particularly important because of its influence on mastic behaviour. The filler improves the resistance properties of bitumen against the action of traffic loads and temperature.

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, EarlyView.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Improvement of compatibility and stability on polyethylene-modified bitumen by use of an aromatic extra as compatibilizer. [PDF]
, 2012 Bitumen modification by polyethylene addition usually improves the mechanical properties of the binder and, therefore, the behavior in service of the bituminous mix: thermal susceptibility and rutting can be diminished, whilst the resistance to low ...

Moisture damage resistance of hot-mix asphalt made with recycled concrete aggregates and crumb rubber [PDF]
, 2017 [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.

Study of the zero shear viscosity of SBS copolymer modified bitumens
Budownictwo i Architektura, 2014 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 ...
