This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

Asphalt pavement distress, the various defects such as holes and cracks, represent a significant engineering and economic concern. It is estimated that pavement defects cause damage costing $10 billion each year in the United States alone [10]. One important step in managing this problem is accurately assessing the pavement condition and its change over time. In this paper we compare three meth...

In this paper, annoyance ratings from traffic noise recorded on cobblestones, dense asphalt, and open asphalt rubber pavements are assessed with regard to car speeds and traffic densities. It was found that cobblestones pavements are the most annoying; also while open asphalt rubber pavement imposes less annoyance than dense asphalt it is not significantly different. Higher car speeds always le...

This report summarizes a detailed report presenting the first and second year of field and laboratory measurements and statistical analyses and performance estimates for tire/pavement noise, permeability, ride quality, distress development, and friction properties of four types of asphalt pavement surface types used by the California Department of Transportation: open-graded asphalt concrete (O...

This brief provides findings on the observed effect of initial pavement smoothness (also known as initial roughness, or as-constructed roughness) on the long-term pavement roughness progression of asphalt overlays. The relationship can be used as a measure for estimating the long-term effect of pavement smoothness and for consideration when developing smoothness specifications and/or payment ad...

Rutting of flexible pavement is considered one of the major pavement distresses noted around the world and in Egypt. Many investigators showed at about 55 to 80% of rutting occurred in the surface layer. Rutting of asphalt surface layer may be due to many causes happened during construction phase and service phase. The main objectives of this research are to evaluate the impact of aggregate gra...

Pavement recycling is an appropriate technology for constructing and restoring road pavement structures due to the limited supply high cost of materials. This study aims improve recycled mix's performance by replacing fine aggregate in mix with Buton Granular Asphalt (BGA). The percentage material (Reclaimed Pavement/RAP) mixture was 20% 30% weight total mixture. BGA added 3%, 6%, 9% each RAP v...
