Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

Abstract This recommendation is based on the results of an inter-laboratory study organised by RILEM technical committee TC 264-RAP "Asphalt Pavement Recycling"—Task Group 3 (TG3) focusing Asphalt Binder for Recycled Mixture. The TG3 aimed to evaluate effect a specific family materials known as asphalt recycling agent (ARA) aged binder under different configurations. Even though ageing irrevers...

This paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. Central composite method was used to design of experiments based on response surface method (RSM). Binder type (Pen 60/70 and Pen 85/100), reclaimed asphalt pavement (RAP) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...

Fatigue characteristics of asphalt binder have an important role in asphalt mix resistance against cracking. Viscoelastic Continuum Damage (VECD) analysis of asphalt binders has been successfully used in highway research works in order to predict fatigue behavior of hot mix asphalt (HMA). In this method an intrinsic property of the material, called damage function is obtained which is independe...

This research aims to utilize glycerin pitch waste as an alternative asphalt binder (extender) in Stone Mastic Asphalt (SMA) mixture. Glycerin (GP) is a by-product from crude glycerol refining process the palm oil oleochemical industry. The method was carried out by testing chemical and physical characteristics of GP comparing it pen 60/70, then based on rheology concrete characteristics. ANOVA...

Hot mix asphalt has various benefits such as good workability and durability. It is one of the most general materials used mixtures in road pavements. Asphalt binders can be improved by modifying them with additives. Gilsonite a natural hydrocarbon which may an additive to hot asphalt. binder modifier (wet process) mixture (dry improve properties mix. provides option rheological properties, sta...

In order to investigate the effect of nano polymer materials on UV aged performance asphalt binder, a PA modifying agent was selected prepare modified asphalt. Under radiation, rheological properties studied. With extension ageing time, microstructure variation characterized by using focused ion beam scanning electron microscope (FIB-SEM). The thermophysical were investigated thermogravimetric ...

Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...

The aim of this study is evaluating the interaction between several base pen grade asphalt binders (35/50, 50/70, 70/100, 160/220) and two different recycled plastics (EVA and HDPE), for a set of new polymer modified binders produced with different amounts of both recycled plastics. After analysing the results obtained for the several polymer modified binders evaluated in this study, including ...
