Ncat 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 کاملEngineering characterisation of epoxidized natural rubber-modified hot-mix asphalt
Road distress results in high maintenance costs. However, increased understandings of asphalt behaviour and properties coupled with technological developments have allowed paving technologists to examine the benefits of introducing additives and modifiers. As a result, polymers have become extremely popular as modifiers to improve the performance of the asphalt mix. This study investigates the ...
متن کاملUtilization of Recycled Asphalt Concrete with Warm Mix Asphalt and Cost-Benefit Analysis
The asphalt paving industries are faced with two major problems. These two important challenges are generated with an increase in demand for environmentally friendly paving mixtures and the problem of rapidly rising raw materials. Recycling of reclaimed asphalt pavement (RAP) is a critical necessity to save precious aggregates and reduce the use of costly bitumen. Warm Mix Asphalt (WMA) technol...
متن کاملLaboratory 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 کاملRheological Characterization of Bituminous Binder containing Wax based Warm Mix Asphalt Additive
Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits. The mechanism of WMA is to use some additives or technologies to reduce the viscosity of bitumen and to modify the rheological behavior of bituminous binders, and thus improve the workability of the mixture at lower temperature. In this study a paraffin wax based addit...
