There is a growing need for the production of a certain types of asphaltic materials having a good rheological properties compared with the non-modified a asphaltic materials can be using as a paving materials.In this re...

Introduction. The fractional composition of the stone filler in asphalt concrete mixtures and the preparation modes of the binder in the "bitumen – mineral powder" system have a significant impact on the performance ...

Chemical modification of asphalt had been used to modify the rheological properties by treatment with sulphur at different experimental conditions. The modification achieved by using application of microwaves (microwave ...

This study investigated the potential of polyvinylpyrrolidone-grafted graphene (PGR) for secondary reinforcement of SBS and microwave-activated crumb rubber (ACR) modified asphalt, aiming to clarify the underlying mechan...

Improving road transportation accessibility is essential for enhancing local social and economic activity in a country. One way to maintain the accessibility of the road network and ensure that users feel safe and comfor...

Polymer-modified asphalts (PMA) are known to improvepavement performance, but they have limitations, such as poor storagestability, oxidation susceptibility, low compatibility, and weak adhesion tomineral aggregates. To ...

ABSTRACT Polymers are being increasingly used for modification of Asphalt to enhance highway pavement performance. This paper describes the polymer modification of two penetration grade Asphalt with ethylene vinyl acetat...

As one of composition materials (asphalt, aggregate, mineral powder) for hydraulic asphalt concrete, the mineral powder has a messy process of manufacture. Comparatively, the cement is easily processed and available for ...

Abstract The research aimed to study the effect of Diols on modification of an asphaltic materials which could be used as a binder for paving material obtained from Qaiyarah asphalt. 0.5-5 wt.% of Diols (ethylene glycol ...

There is a growing need for the production of certain types of asphaltic materials having good rheological properties compared with the unmodified asphaltic materials, thus many experiments were performed to prepare a mo...

The research work was aimed to prepar different types of asphalt.  Beji asphalt was mixed with polymers such as polystyrene, melamine-formaldehyde resins and poly methyl methacrylate. The amount of polymer added varied ...

There is a growing need to produce asphalt materials with high economic feasibility, that is the production of asphalt materials with rheological properties that differ from the base asphalt (unmodified asphalt), can be ...

The performance of asphalt mixtures modified with 7% and 10% waste tire and solid natural rubber is assessed in this study, along with the effects of replacing fine aggregate with these materials. According to binder tes...

ABSTRACT The study included the use of  two path in the process of preparation.The first pathway included preparation of the AC from Baiji asphalt by an oxidation process done at 350 °C using 2% FeCl3 for 3hours, after...

Warm Mix Asphalts (WMAs) have been developed with the objective of minimizing the CO 2 emissions in the production and placement process of Hot Mix Asphalts (HMAs) by reducing temperatures at which these are mixed and co...

In this study, a mixture of two polymers consisting of commercial adhesive [ethylene vinyl acetate (EVA)] and melamine (M) Which were used in this study. Different weights of both polymers were used with total weights eq...

This study has included a modulation of the rheological properties of asphalt by a catalyst chemical treatment with polycarbonate, and the microwave technique was used at a power of (360) watt at time intervals. Furtherm...

In this study, we modify the rheolgical prioperties of asphaltic materials by addative and air blowing. For this process, asphaltic materials have been oxidized by air blowing in the presence of anhydrous aluminum chlori...

The permanent deformation performance of asphalt concrete is strongly dependent on the rheological properties of the asphalt binder. It has been recognized that the asphalt’s low shear viscosity (LSV) characterizes the...

This study was included treatment of the Dura asphalt with lignin as a natural polymeric additive and air blowing with three paths. The first path: the rheological properties of the asphalt were modified by adding the l...

The research was aimed to use the residual asphaltic materials taken from northern refinery in the preparation of activated carbon by oxidation with V O5 in the presence of a stream of air for 3hrs at 350°C temp, .The r...

Abstract This study aims to develop a performance grade (PG) zoning map for asphalt pavements along the Kabul–Salang Highway in Afghanistan, considering local climatic conditions and traffic factors, to support optimiz...
