Laboratory Evaluation and Pavement Design for Warm Mix Asphalt
For many years, the asphalt industry has been aware of the energy savings and environmental benefits inherent in cold mix or warm mix asphalt technologies. Environmental awareness and the need for improved energy efficiency has increased rapidly over the past few years and extensive measures such as the air pollution reduction targets set by the European Union under the Kyoto Protocol have enco...
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...
متن کاملEffects 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 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 کاملInvestigation of Warm-Mix Asphalt Using Iowa Aggregates
The implementation of WMA is becoming more widespread with a growing number of contractors using various WMA technologies. Early research suggests WMA may be more susceptible to moisture damage than traditional HMA mixes. Asphalt performance tests can be a good way of measuring material responses that can be correlated with pavement performance. It is important for owner/agencies to know that t...
