Preparation and Performance Characterization of Warm-Mix

However, the application of RAP in hot-mix asphalt (HMA) and warm-mix asphalt (WMA) technology may face the problem of secondary aging of asphalt [6, 7], which significantly weakens the performance and service life of the corresponding asphalt-mixture and pavement structure [8, 9].

A novel approach for rational determination of warm mix

Warm Mix Asphalt additives can enhance aggregate coating even when mixing at 115 °C. Stiffness and strength of organic warm mix asphalt significantly correlates with the mixing temperatures. Studied WMA additives improved asphalt compactability more than it enhanced aggregate coating.

HOT-MIX ASPHALT VOLUMETRICS REVISITED: A NEW PARADIGM

HOT-MIX ASPHALT VOLUMETRICS REVISITED: A NEW PARADIGM. As early as 1905, Richardson recognized the importance to performance of the relative proportions, by volume, of the material components of bituminous mixtures. In the 1940s, Marshall explicitly addressed the volumetric percentages of air voids and of the degree of void saturation by asphalt.

Influence of Selected Warm Mix Asphalt Additives on Cracking

Warm mix asphalt technology is continuously gaining bigger share in total production volume of asphalt mixtures. This is due to the fact that it offers considerably advantages over traditional hot mix asphalt, both in terms of technical aspects as well as in environmental issues [1,2,3], which is indispensable in today’s economy.
