Environmental issues and sustainable development are key factors where asphalt pavement technology can play an even more positive active role in the future. Asphalt is ideally suited for recycling and re-use of materials, meeting the challenges of limited material resources. It has potential to reduce global warming through low energy concepts for mix production and placing. Furthermore, it allows meeting specific environmental demands of denser populated agglomerations, such as reduction of traffic noise by introducing new innovative materials and designs as well as reductions of congestion from road works by improving durability and aging resistance. Hence, it is now time to establish a holistic way of approach and introduce this concept in life cycle analysis as well as research and development.

In order to form a coordinate platform for progress in this field and based on the achievements of the Symposium ISAP2008 August 18th to 20th in Zurich ( a new ISAP Technical Committee TC APE Asphalt Pavement and Environment has been formed.

The goals of this TC APE are

· Promote recycling of asphalt as sustainable material of high value by considering technical, environmental and economical aspects.
Re-use as much as possible at quality levels as high as possible.

· Promote safe and beneficial re-use of second mat. in asphalt

· Find new solutions and new techniques to improve the environmental compatibility of asphalt pavement

· Find new solutions and new techniques for asphalt pavements to improve environment (e.g. multifunctionality)

· Find new solutions and new technique & understand mechanisms!!

· Link with other international groups, e.g. RILEM TC SIB, WG05 Recycling and WG06 on Cold Recycling and the recently established RILEM TC RAP - Asphalt Pavement Recycling.

2018 ISAP Conference - Fortaleza, June 19-22, 2018

Topic: ../nonews

The International Society for Asphalt Pavements (ISAP) is a volunteer organization of professionals and experts in asphalt engineering whose goal is to share the latest in leading edge asphalt pavement technology worldwide.

The ISAP Conference on Asphalt Pavements has been the major source of state-of-the-art and state-of-the-practice information in asphalt technology since its first meeting in Ann Arbor, Michigan, USA in 1962. The ISAP Conference meets every four years, and the 13th ISAP Conference on Asphalt Pavements will be held in Fortaleza, Ceará, Brazil, on June 19-22, 2018.

The ISAP 2018 Conference will be an opportunity to examine the future directions of the asphalt paving industry in terms of key sustainable issues, such as long-term performance, environmental protection, socio-economic impacts, and political concerns. The ISAP 2018 Conference will address these critical issues in the four major areas of asphalt pavement engineering, i.e., design, materials, construction, and preservation.

4th APE ISAP Symposium - November 20-21, 2017 - Tokyo

Topic: ../nonews

ISAP (International Society for Asphalt Pavement) is the most prestigious international organization to promote asphalt pavement technologies. The Technical Committee on Asphalt Pavement and Environment (APE) is one of the technical committees in ISAP and hosts this Symposium together with ISAP APE Symposium 2017 Organizing Committee in Japan Road Association Pavement Committee.

The ISAP APE Symposium 2017 provides a stage for exchanging information on a wide variety of topics related to asphalt pavements and environment. The Symposium has already been organized three times, 1st in Zurich, Switzerland, 2nd in Fortaleza, Brazil, 3rd in Sun City, South Africa, and the 4th Symposium will be held in Tokyo, Japan, for the first time in Asia.

The 4th Symposium will be held in conjunction with the Highway Technology Fair 2017 which is one of the big technology exhibitions on road maintenance in Asia. The Fair will present many good examples of pavement technology.

Pavement recycling technologies in Japan have about 50 years of history and new technologies such as cold pavements are also developed in view of the Olympic and Paralympic Games in Tokyo in 2020.

The Symposium in 2017 will provide a very good opportunity to exchange the experience and new approaches on the positive effect of pavements on the environment and will foster progress and dissemination of sustainable pavement technologies in Asia and the rest of the world.

3rd APE ISAP Symposium - 16th August 2015 at Sun City

Topic: Conference_Announcements

 ISAP offers a forum through its Technical Committee TC APE, for international asphalt pavement technology enhancement, research and information exchange. Following the tradition of previous such events in Zurich and Fortaleza, this ISAP APE Symposium 2015 is linked to CAPSA2015, a locally established conference, aiming to enhance the international contributions to the events. ISAP TC APE also aims to dovetail with CAPSA 2015, bringing an international perspective of research and development, with creative, sustainable solutions for flexible pavements.

The ISAP APE Symposium programme has been developed to enable highly relevant papers with substantial findings to be presented in plenary sessions, accompanied by a broad cross section of pertinent subjects covered in parallel sessions. An ISAP APE poster session with selected, quality papers is aimed to stimulate lively discussions. Selected posters from ISAP APE Symposium will also be displayed at the CAPSA 2015 conference.

Symposium Chairmen: Kim Jenkins, Lucas Ebels, Manfred Partl (TC APE Chair), Gabriele Tebaldi (TC APE Secretary)
