The properties of nanosilica-modified asphalt cement
Petroleum Science and Technology, 2016ABSTRACTThis study aimed to investigate some engineering properties of asphalt cement modified with different percentages of nanosilica. 60/70 Penetration grade asphalt cement was modified with different percentages of nanosilica (i.e. 1, 3, and 5 wt%) and their properties were evaluated.

Physical and rheological properties of acrylate–styrene–acrylonitrile modified asphalt cement
Construction and Building Materials, 2015Abstract Polymer-modified asphalt cement (PMAC) has been used in the last few decades to mitigate several root causes of asphalt-cement failures. Furthermore, it has been proved that polymers used as asphalt-cement modifiers had significant influence on the properties of asphalt at low and high temperatures. The primary objective of this study was to

Predicting a Model for Modified Asphalt Cement Rutting Parameters
Key Engineering Materials, 2021This paper aims to investigate the relationship between the Superpave rutting parameter of asphalt (G﹡/sin δ) by conducting Dynamic Shear Rheometer (DSR) tests with the rut depth values obtained by the wheel track device. The twenty asphalt mixtures have

Behavior of Reclaimed Polyethylene Modified Asphalt Cement for Paving Purposes
Journal of Materials in Civil Engineering, 2011The present paper deals with the procedure for modification of 80/100-paving grade asphalt cement using reclaimed polyethylene (PE) derived from low-density polyethylene carry bags collected from domestic waste. The details of the preparation of the PE-modified binder and the results on variation of binder properties with blending temperature and ...

Properties of Portland cement-modified asphalt binder using Superpave tests
Construction and Building Materials, 2011Abstract This study investigates the effect of cement additive on some properties of asphalt binder using Superpave testing methods. Six cement-to-asphalt (C/A) ratios were considered in the study: 0.05, 0.10, 0.15, 0.20, 0.25 and 0.30 by volume of asphalt binder.

Laboratory Investigation of Recycling for Aged SBS Modified Asphalt Cement
Pavements and Materials, 2011This research focused on the recycling of aged styrene-butadiene-styrene (SBS) modified asphalt cement. The physical properties and rheological properties of aged SBS modified asphalt cement were evaluated based on force-ductility test and Strategic Highway Research Program (SHRP) binder tests.

Physical Properties of Tall Oil Pitch Modified Asphalt Cement Binders
, 1995In recent years, significant advances in asphalt modifications have been achieved, particularly in the field of polymer modified asphalt cement binders. Concurrently, environmental concerns and recycling processes are becoming a part of our everyday life. Tall oil pitch (TOP) is a by-product of the kraft process in the pulp and paper industry.
