Recently, the use of fibers has become an attractive option to be implemented as reinforcement in Asphalt Concrete (AC) mixtures. Nonetheless, few studies have been carried out evaluate recyclability potential AC mixtures incorporating fibers. In this study, reinforcing effect polyacrylonitrile (PAN) is investigated. Air voids, Marshall stability, indirect tensile strength (ITS), moisture sensi...

One option that has the potential to be applied road roughness is reuse of Reclaimed Asphalt Pavement (RAP) material. RAP material can reused by adding new asphalt and aggregate in accordance with composition mixture so it expected obtain quality as planned. efforts made improve use modified additional form styrofoam. The styrofoam technical properties a mixture. This research was conducted var...

This study analyses the possibilities of using up to 30% reclaimed asphalt pavement as a substitute material for natural aggregate, along with fly ash replacing 20% or 40% Portland cement in stabilizations 4% and 6% binder. The Proctor test was used determine maximum dry density optimal moisture content cement-based stabilizations. compressive strength tested after 7, 28, 90 days. Parameters in...

Asphalt additives, in general, aim to improve the performance of asphalt mixtures by enhancing their durability and resistance cracking other forms damage. additives can be natural or synthetic, some are biodegradable. Natural such as reclaimed pavement, much more environmentally friendly than synthetic ones. Using help reduce environmental impact mix while its performance. This study aims eval...

Committed to converting the Port of Balboa into a major transshipment hub, Panama Ports Company (PPC) launched in 2006 a $300-million expansion program to increase berthing and stacking space that would almost triple the port capacity. The site’s history of marine-related activities, deteriorating facilities, buried structures, and poor soils mandated significant investment in clearing and prep...

Basic oxygen furnace slag (BOF) is widely used in road construction, but there is a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA), containing stone mastic asphalt (SMA), porous asphalt (PA), and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag co...

In the present study, effects of adding fibers and Reclaimed Asphalt Pavement (RAP) on low temperature performances open graded asphalt mixtures for surface layer dense surface, binder, base layers were investigated. Two different kinds used: a combination aramid polyolefins utilized preparing fiber reinforced porous mixtures, while polyacrylonitrile employed producing conventional layers. Refe...
