Use of inverse method for bonding quality assessment between bitumen and aggregates under asphalt mixes manufacturing conditions [PDF]

, 2012
In roads building, classical asphalt mix manufacturing commonly requires the heating (at 160°C) and the complete drying of aggregates. The induced energy cost has opened the way to develop alternatives processes and materials with low energy/carbon ...

Designing warm – mix asphalt with the zeolite addition

Budownictwo i Architektura, 2013
The purpose of this paper is to discuss the design of warm-mix asphalt. One way to reduce the temperature of bituminous mix is the use of zeolite. The article shows the lack of differences in designing WMA recipe with zeolite addition compared to the HMA.
