When it comes to asphalt pavement preservation, the magic is in the maltenes.

The goal of these pages is to explain the naturally resilient chemistry Pavement Technology refers to as Maltene Replacement Technology (MRT), and its demonstrative benefits in comparison with alternative methodologies for preserving asphalt pavements. Use the links below to delve more deeply into each concept discussed or use the form on this page to request a comprehensive white paper on this topic.

Check out the Spring 2020 issue of the Pavement Preservation Journal for the more information on MRT.

Sustainable Asphalt Pavements: The Science Behind Maltene Replacement Technology

In recent years, there has been no shortage of confusion (and some intentional misdirection) in the asphalt pavement preservation marketplace regarding the definition and understanding of maltenes and the role they play in rehabilitating and extending the life of asphalt roadways. Let’s clear up the confusion.
