Highway trial sections: Performance evaluation of warm mix asphalt and recycled warm mix asphalt

Construction and Building Materials, 2020
Abstract The present article presents the construction and evaluation of an experimental stretch of highway with environmentally sustainable mixes; warm mixes asphalt and recycled warm mixes asphalt. Six trial sections of an urban highway were constructed with different structural characteristics. Each section was 15 cm thick and 90 m long.

Warm mix asphalt: an overview

Journal of Cleaner Production, 2012
One of the causes of pollution associated with the construction of transportation infrastructures is the emission of greenhouse gases into the atmosphere. Even though the use of Warm Mix Asphalt technology has many advantages that are not related to the reduction of gas emissions, WMA technology is also good for the environment because it produces ...

Long term performance of warm mix asphalt versus hot mix asphalt

Journal of Central South University, 2013
The fatigue behavior, indirect tensile strength (ITS) and resilient modulus test results for warm mix asphalt (WMA) as well as hot mix asphalt (HMA) at different ageing levels were evaluated. Laboratory-prepared samples were aged artificially in the oven to simulate short-term and long term ageing in accordance with AASHTO R30 and then compared with ...

Shanghai Experience with Warm Mix Asphalt

Paving Materials and Pavement Analysis, 2010
Warm mix asphalt (WMA) technologies have been developed to mix, transport, pave, and compact asphalt mixture at temperatures up to 40°C lower than the conventional hot-mix asphalt (HMA). The benefits of WMA include energy savings, lower CO2 emissions, and reduced workers’ exposure to fumes, reduced binder ageing, and faster release of pavement to ...

Warm Mix Asphalt

2014
Warm Mix Asphalt (WMA) technologies have potential to reduce the application temperature of Hot Mix Asphalt (HMA) and improve workability without compromising the performance of asphalt pavement. This promises various benefits, e.g. a reduction in greenhouse gas emissions, decreased energy consumption and costs, improved working conditions, better ...

Moisture susceptibility of Warm-Mix Asphalt

2014
ABSTRACT: Economic, environmental, and engineering benefits led to the rapid implementation of Warm-Mix Asphalt (WMA) during the past decade. While WMA technologies are generally performing well to date, development of standard mix design protocols continues and performance questions remain.

Evaluation of warm mix asphalt containing recycled asphalt shingles

Construction and Building Materials, 2014
Abstract Advances in asphalt materials have led to the incorporation of higher amounts of recycled asphalt materials in mixtures that can be produced at reduced temperatures. Two demonstration projects were constructed to assess the performance of mixtures that use warm mix asphalt (WMA) and recycled asphalt shingles (RAS) at reduced temperatures ...

Empirical Study of Warm Mix Asphalt Incorporating Recycled Asphalt Pavement

2021
The depletion of natural resources along with the progressive change of climate due to high heat and harmful gas emission into the atmosphere are the concerns engineers, scientists and politicians have been addressing and cooperating toward finding efficient solutions to palliate to this global issue.

Research on the Performances of Warm Asphalt and Warm Mix Asphalt with Sasobit

ICCTP 2010, 2010
This paper studied the impact of Sasobit on the performance of asphalt and asphalt mixtures. The normal performance tests on asphalt indicate that when the quantity of Sasobit increases, the penetration index (PI) and the softening point increases; but the penetration and the ductility in the low temperature range reduces.

High temperature characteristics of warm mix asphalt mixtures with nanoclay and chemical warm mix asphalt modified binders

Journal of Cleaner Production, 2016
Abstract With the rising price of energy and the effects of global warming, the demands for the use of warm mix asphalt (WMA) in the construction of pavements have been steadily increasing throughout the world. Due to this, many agencies have been looking forward to implementing WMA technology as a way to promote green culture in every aspect of the ...
