As a fair deck pavement material of its kind used in steel bridge, the epoxy asphalt concrete is considered much more superior to ordinary asphalt concrete in terms of road performance, while still greatly subject to the level of design and construction. Starting from a practical case of the epoxy asphalt concrete that has been applied in the deck pavement of Pingsheng Steel Bridge, this paper ...

Historically, research has shown that it is neither physically possible nor economically feasible to construct an asphalt concrete pavement surface that provides skid resistance at an adequate level throughout the pavement's service life. Consequently, engineers utilize a seal coat maintenance technique as one way of improving friction performance on roadways. This maintenance technique consist...

Waste utilization has gained more and more interest. In this study, crumb rubber and diatomite were used to modify asphalt binder and the short-term aging effects on the properties of modified asphalts were evaluated. Three kinds of modified asphalt were prepared; they are diatomite modified asphalt (DA), crumb rubber modified asphalt (RA), and diatomite and crumb rubber compound modified aspha...

Crude oil is one of the most important energetic resources in the world. It is used as raw material in numerous industries, including the refinery-petrochemical industry, where crude oil is refined through various technological processes into consumer products such as gasoline, oils, paraffin oils, lubricants, asphalt, domestic fuel oil, vaseline, and polymers. Oil-derived products are also com...

Fatigue cracking is an essential problem of asphalt concrete that contributes to pavement damage. Although stone matrix asphalt (SMA) has significantly provided resistance to rutting failure, its resistance to fatigue failure is yet to be fully addressed. The aim of this study is to evaluate the effect of crumb rubber modifier (CRM) on stiffness and fatigue properties of SMA mixtures at optimum...

Cohesion properties of the binder matrix within asphalt mixes and adhesion characteristics of the asphalt binder and aggregate particles are the two major mechanisms resisting against cracking in asphalt mixes. This study is focused on estimating crack resistance of asphalt mixes at intermediate temperatures through evaluation of cohesion and adhesion properties of binder-aggregate systems usin...

Fuel oil leaked onto asphalt pavement will damage the layer by dissolving binder, softening mixture and finally resulting in distress such as raveling pitting. In meantime, skid resistance, high temperature stability water deteriorate dramatically. Silicone resin is a fog sealing material for pavement. It forms three-dimensional network structure with -Si-O- chains therefore shows strong hydrop...

The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...

This study aims to quantify and compare the life-cycle environmental, economic and social impacts of two pavement materials: namely 10mm Asphalt Rubber Stone Matrix Asphalt (ARSMA10) and 10mm Polymer Modified Stone Matrix Asphalt (PMSMA10). To achieve this objective, a comparative sustainability framework was developed by: 1) combining the Life Cycle Assessment (LCA) with pavement maintenance p...

The performance of asphalt binders at high and low temperatures has an important role on the rutting and crackingresistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphaltphysical and mechanical properties and helps reducing environmental pollution. In this research, three unmodifiedand six CRM modified binders were teste...
