Did you know Russia is implementing Superpave specifications? I found it out during my first visit to Moscow at the conference "Organic Binders in Road Construction" on 21-23. November 2018.

Comparison of two low-temperature cracking tests for use in performance-based asphalt mixture design

Which performance test to use for designing mixtures and controlling quality? This was the question I was asked in Latvia. Here is an article describing why I recommended TSRST for inclusion in Latvian national road specifications.

The industry journal Asphalt&Bitumen has published an article about our work on performance-based mixture design (in german). I hope this brings the research results closer to the practical use by the industry! The article can be accessed here. 

Newspaper article in Tages Anzeiger

Tages Anzeiger in Switzerland wrote an article about our research. It's in German, so you will have to learn the language before finding out the secret sauce to recycling:)

New paper: How to reduce reclaimed asphalt variability: A full-scale study

posted Aug 28, 2018, 7:14 AM by Martins Zaumanis   [ updated Sep 4, 2018, 7:55 AM ]

Variability is one of the main causes limiting production of highly recycled asphalt. But there are methods to improve it. In the paper I quantify by how much can the variability be reduced through milling and stockpile mixing operations. It turns out that highly variably pavement can still be used at up to 40%, if the right homogenization procedure is applied.

Article on rejuvenator addition location in asphalt plant

posted Jul 9, 2018, 4:26 AM by Martins Zaumanis   [ updated Jul 12, 2018, 1:39 AM ]
How to apply rejuvenators to achieve maximum efficiency? If this is a question that does not let you sleep at night, please my new article. We performed a full scale trial to compare two rejuvenator addition points: on hot RAP versus on cold RAP. Then we analyzed the RAP binder to see if there are any differences. Hint: there were none, but that is a good thing! See why in the full article

The positive results encouraged us to continue the research and soon an article concerning rejuvenator addition spot effect on mixture properties will also be published.

ISAP 2018 conference presentation (and party)

posted Jun 28, 2018, 4:29 AM by Martins Zaumanis   [ updated Jul 9, 2018, 4:28 AM ]

The ISAP conference 2018 in Fortaleza demonstrated some interesting studies from all parts of the world. I presented a study on using performance-based test methods to balance the mixture performance. But that was non all. This is Brazil after all. The highlight of the conference was the evening party where everyone gave in to the Brazilian rhythms. 

Presentation at E&E event 2018

I had the challenging task of delivering a presentation on communication at the E&E event 2018 in Berlin. It was a new kind of experience to give a non-technical presentation. The session was a big success, encouraging people to think about means to sell asphalt industry to the young generation.

Funded PhD position for 100% RAP recycling

posted May 17, 2018, 6:53 AM by Martins Zaumanis   [ updated May 17, 2018, 6:56 AM ]

SAFERUPA PhD position is offered within a H2020 Research Project SAFERUP! in Latvia on the topic of 100% asphalt recycling under supervision of Martins Zaumanis.  
We are looking for early stage researchers with a degree in material science, chemical, mechanical or civil engineering. The project will deal with asphalt mixture aging, performance testing, and modeling. 
The call is open and will be closed on July 7th 2018. Expected start is September 1st 2018 for a duration of 36 months with a fully payed tuition according to H2020 rules. 
More information regarding the research project, the requirements and how to apply can be found on the SAFERUP!Website.
SAFERUP! aims to provide the European community with innovative solutions that will form the urban paved environment of the future. Footpaths, bike lanes, roads, intersections, squares and all other walkable surfaces that we all use every day will be designed, constructed and managed to meet context-sensitive criteria including not only safety, mobility and costs (construction and maintenance), but also sustainability, environmental impacts, accessibility, aesthetics, circular economy and local economy preservation.
