Application of Epoxy-Asphalt Composite in Asphalt Paving Industry: A Review with Emphasis on Physicochemical Properties and Pavement Performances

The asphalt paving process

Language: English The Challenge At the outset the asphalt paving process seems to be simple. Trucks deliver hot mix asphalt from plants to the construction site. There the asphalt is loaded on asphalt pavers that evenly spread the asphalt. Finally, compactors compact the asphalt to its required density. Despite this relatively structured process our research shows that there are significant dis...

Investigation of Clay Balls in Asphalt Pavement

Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is 8 mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate 9 contamination of clay or soil, high aggregate moisture, and low production temperature at the 10 asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being 11 liquefied an...

Study on Performance of Epoxy Asphalt Concrete Applied in the Deck Pavement of Pingsheng Steel Bridge

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 ...

Patch Distress Detection in Asphalt Pavement Images

Pavement condition assessment is an indispensable constituent in maintaining roadway infrastructure. Current practices for pavement condition assessment are labor intensive which introduce subjectivity in pavement rating and are time consuming. Automated methods rely on full 3D reconstruction of the pavement surface which introduces high equipment and computation costs. This paper presents a me...
