As one of the top twenty economies in the world, Turkey is drawing attention owing to the major infrastructure projects it has carried out in recent years. Every new project that has been planned and completed in Turkey also brings with it an increased traffic burden on our roads. It is quite essential to select a specific type of road surface that can safely transport the constantly increasing traffic, have a longer life cycle, and require less maintenance while also providing better performance for users.
Pavement that safely supports traffic and ensures that loads are transferred to the road base also has a significant effect on road performance owing to the skid resistance, driving comfort, and low noise level that it provides. Road pavement are generally divided into two main categories across the world: 1) Flexible (asphalt) pavements that use bitumen as the binding material and 2) rigid (concrete) surfaces that use hydraulic-based cement as bonding material. In addition, there is a third type is called a composite surface that combine both surfaces.
Rigid pavements, or concrete roads as they are more widely known, have high resistance, supporting strength and bending strength thanks to their hydraulic cement-based binding materials. Concrete roads are built in different forms depending on their joints and whether they contain reinforcement. They include jointed plain concrete pavement roads (JPCP), jointed reinforced concrete pavement roads (JRCP), continuously reinforced concrete pavement roads (CRCP), and roller compacted concrete roads (RCC). A good knowledge of these types of pavements, which may have advantages over one another depending on actual traffic load, environmental conditions, practicability and economic conditions, is of great importance, especially for using other technologies in countries where only one road pavement is dominant.
The total length of roads classified as motorways, national roads, and provincial roads, which are supervised by the KGM (General Directorate of Highways), was 67,333 kilometers as of January 1, 2019. Around 36% of this road network are HBMs, 58% of it are surface treatment, and the remaining roads consist of gravel, stone pitched and dirt roads. The first concrete road was built as a 2 km one-way section for test purposes at the Afyon- Emirdağ junction in 2004, while the second one was built as a 3.5 km one-way section between Hasdal Junction and Kemerburgaz in 2006 within the roads supervised by KGM, and the under protocols concluded between KGM and TÇBM. Aside from those roads, two pilot roads were built between Ordu and Ulubey and in the Karamürsel city crossing in 2007 and 2010, respectively.
Meanwhile, the road pavement for “The Kemaliye-Dutluca Tunnels and Link Roads, and the Kemaliye and Kozlupınar Viaduct”, whose tender was awarded in 2017, has a total length over 21 km, and was designed as a rigid concrete road. Thus, the KGM’s efforts to build concrete roads have gained momentum in light of developments within the country and abroad, and it issued the Technical Specifications for Concrete Roads in 2016. Works on the Guide for Designing Rigid Pavement Surfaces are still ongoing.
The responsibility for roads that do not fall within KGM’s area of responsibility rests on the Metropolitan Municipalities and Provincial Special Administrations. While the length of these roads and the distribution of road pavements are not precisely known, their total length is estimated to be in excess of 350,000 km. These roads include different types of concrete sections.
To be organized under the auspices of the Ministry of Transportation and Infrastructure, and with technical support from the Turkish Cement Manufacturers’ Association of Turkey (TÇMB) and the European Concrete Paving Association (EUPAVE), the ”First Concrete Roads Congress and Exhibition” aims at bringing the stakeholders in the industry together. The purpose of this convention is to contribute to the development of a sustainable transportation system that supports our country’s competitiveness and boosts society’s quality of life, all the while providing safe, accessible, cost-effective, comfortable, rapid, environmentally-friendly, uninterrupted, balanced and contemporary services. It also intends to show that concrete roads are used as an alternative to other roads in both Europe and the USA and in the rest of the world, since they are durable, cost-effective, comfortable and safe, and the convention will also ensure that different aspects of concrete roads are assessed in line with the technological advances and the studies carried out on concrete roads in our country, despite the fact that these roads have rarely been preferred so far.
During the event, an exhibition will be organized that will be attended by national and international project implementing entities (designers, contractors, consultants) and by producers of machinery, equipment and materials that are used for the design, manufacture, and application of concrete roads, concrete barriers, permeable concrete and other road and road-building components.
We are inviting representatives from the relevant departments of universities and from the departments of organizations and agencies that deal with this subject, as well as the stakeholders in the national road industry, to take part in the “First Concrete Roads Congress and Exhibition”, which will assess different aspects of concrete roads, either by preparing presentations or attending them as listeners, or by taking part in the exhibition.
