His presentation will focus on Pavements in Warm Climates issues and provide examples on successful pavement designs and construction practices in the USA and around the world. Three overall themes will be presented: the first one will address the urban heat island and climate change impact on asphalt pavements; the second theme will include an overview of modified asphalt pavements including typical designs and construction practices; the third theme will debate current and future challenges regarding laboratory test methods to insure quality materials and assessment of future performance.


Monday 6 April 2015, 09:00 - Pavements in Warm Climates: Challenges and Considerations to Improve Performance

Pavement performance can be greatly impacted by environmental factors such as temperature and moisture. Asphalt pavements in warm climates will continue to possess challenges in their design and materials selection to satisfy minimum durability, safety and social attributes. The increasing trend in climate change may further emphasize the need for innovative sustainable pavement designs and the use of modified pavement systems. The State of Arizona, USA, is located in a hot arid climate where temperatures in the summer can reach 50 degrees C. Historical records also showed that the City of Phoenix, Arizona has experienced a significant climate change over the past 50 years. Specifically, pavement design and materials selection has evolved over the years to address challenges of this unique climate. The department of transportation in conjunction with Arizona State University have conducted several laboratory and research studies to provide guidance on performance testing and obtain engineering properties for future asphalt mixture designs. This research effort complements the greater goal on continuing the path of transportation sustainability.

Guest Speaker
Gulay Malkoc

Gulay Malkoc is the Technical Director in ASMUD, the Turkish Asphalt Contractors Association. Prior to joining ASMUD in 2003, she worked in the General Directorate of Highways in the Technical Research Laboratory Department in Turkey and was appointed by the European Commission as an independent evaluator for FP7 projects. She is also a member of the European Standardization Committee (CEN) TC 336 for bituminous binders and the Chairman of a Mirror Committee in Turkey.

Her technical publications span multiple areas and disciplines including bituminous binders, bitumen emulsions and polymer modified binders. She also excelled in national and international activities relating to health and safety and is consistently involved in the organization of international scientific conferences.

Tuesday 7 April 2015, 09:00 - New Approach and Data Assessment on the European Bitumen Specification

In Europe, more than 80% the road network is paved with asphalt. The overall network quality is an important factor for the economic growth of Europe and is thus accepted as a strategic "asset". To service this approach, the European asphalt industry has the responsibility of constructing durable roads with a sufficient lifespan and to consider sustainability issues such as environment and safety aspects and value for money.

One important measure to enhance the durability of asphalt is the introduction of the performance-related (P-R) specifications/contracts and the Build-Operate-Transfer Schemes. These approaches are based on clearly defined and predictable pavement durability. For asphalt mixtures, P-R specifications were introduced with EN 13108-series in 2006, whilst P-R bitumen specifications are still not fully implemented in EN 12591 (paving grade bitumen), EN 14023 (PMB's) or EN 13924 (hard grades) drafted by CEN TC336/WG1. Although the bituminous binders are predominant in asphalt mixtures that have a major influence on the final performance, the reliable correlations between bitumen and asphalt mixture properties are essential to predict durability of asphalt mixtures.

This presentation is regarding the current situation of the binders' specs in Europe and the ongoing EU funded project FunDBitS. The new internationally available data will be presented and reviewed in order to develop P-R bitumen characteristics. By involving all stake-holder parties in the project, the required discussions on the feasibility of test procedures and the results for the specification will shorten the later discussions in CEN TC336 committees.

Modified Bitumen for Paving Roads and Airports

Highway and airport pavements in the Middle East are subjected to extreme hot temperatures and escalating heavy loads due to the economic growth. To make sure the pavements can take these conditions, and provide cost effective service life, consultants in the region are specifying Polymer Modified Bitumen (PMB) in the tender documents for most projects. Saudi Arabia and Qatar requires PMB in all expressway and airport projects. Consultants in the UAE are requiring the same for all major airport projects.
