Effects of Warm-mix Asphalt Additives on Asphalt Mixture Characteristics and Pavement Performance
The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...
متن کاملEffect of Reclaimed rubber Modification on the Rheological Properties and Rutting Resistance of Asphalt Binders
In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves ...
متن کاملNcat Evaluates Warm Mix Asphalt
In addition to lower emissions warm mix asphalt has several advantages over hot mix asphalt such as fuel energy savings, decreased binder aging and an extended paving season (Photo courtesy: Matthew Corrigan, FHWA) The National Center for Asphalt Technology (NCAT) is evaluating warm mix asphalt (WMA) technologies. WMA technology allows the mixing, lay down, and compaction of asphalt mixes at si...
متن کاملThe Effects of Different Binders on Mechanical Properties of Hot Mix Asphalt
To determine the behavior of hot mix asphalt including different penetration grade bitumen has been a major subject of paving engineering. In this study the effects of different penetration grade binders on the mechanical properties of hot mix asphalt were investigated with four different tests. The specimens prepared with AC-5, AC-10, AC-20 and SBS modified AC-10. The stiffness modulus, creep ...
متن کاملStudy of Surfactant Additives for the Manufacture of Warm Mix Asphalt: From Laboratory Design to Asphalt Plant Manufacture
Warm Mix Asphalt (WMA), manufactured at a lower temperature than the traditional Hot Mix Asphalt (HMA), allows for important economic and environmental benefits when considered for application in roads. Nonetheless, despite the benefits, its application in pavement for roads is not as widespread as desired from an environmental point of view; more in-depth studies to investigate its development...
