Choosing pavement type is a challenging and much-debated issue among public authorities. It includes engineering factors such as materials, labor, and long-term performance within the scope of the initial (construction) and life-cycle costs. In recent years, given the significant public expenditure on road construction and rehabilitation processes, the trends in vehicle ownership caused by an increasing need to travel, and the decrease in local resources, concerns have been raised about the efficiency of pavement coating types. To ensure that taxpayers understand the full value of road expenditure, it is important to identify a coating type selection process that seeks to include the most appropriate construction, maintenance, and repair strategies possible. In this study, an LCCA was performed for a 2.2 km–long Roller Compacted Concrete (RCC) test track constructed in Kocaeli city. If asphalt is chosen instead of RCC as the coating preference, the economic factors that may arise at a national scale (in this case, Turkey) are discussed. During the 20-year service period, maintenance, repair, and rehabilitation planning were carried out on the basis of a 30-year analysis period. In terms of initial construction costs, an RCC road is 39.4% more economical than an asphalt road and provides maintenance and repair economies of 62% during the service period. In terms of life-cycle costs, an RCC road is a 46% more economical paving alternative than an asphalt road. Although the first serious maintenance activity was carried out in the 10th and 20th years of the asphalt road, it was significant that it only took place during the 20th year for the RCC road, and the asphalt maintenance material was more expensive than that for the RCC road.

Türkiye'de Rijit ve Esnek Üstyapı Kaplamalarının Yaşam Döngüsü Maliyetlerinin Karşılaştırmalı Bir Değerlendirmesi

Kaplama tipinin seçimi kamu yetkilileri arasında zorlu ve tartışmalı bir konudur. Bu süreç, başlangıç (inşaat) ve yaşam döngüsü maliyetleri kapsamında malzeme, işçilik ve uzun vadeli performans gibi mühendislik faktörlerini içermektedir. Son yıllarda, yol yapımı ve rehabilitasyon süreçlerine harcanan önemli kamu giderleri, artan ulaşım talebinden kaynaklanan araç sahipliği eğilimleri ve yerel kaynaklardaki azalma göz önüne alındığında, kaplama tiplerinin etkinliği konusu tartışılmaya başlanmıştır. Vergi mükellefi olan halkın, yol harcamalarının tam değerini anlayabilmelerini sağlamak için, mümkün olan en uygun inşaat, bakım ve onarım stratejisini hedefleyen bir kaplama tipi seçim sürecinin belirlenmesi önemlidir. Bu çalışmada Kocaeli ilinde inşa edilen 2,2 km uzunluğundaki Silindirle Sıkıştırılmış Beton (SSB) test yolu için bir yaşam döngüsü maliyet analizi yapıldı. Kaplama tercihi olarak SSB yerine asfalt seçilirse, ulusal ölçekte (bu çalışmada Türkiye) ortaya çıkabilecek ekonomik faktörler tartışılmıştır. 20 yıllık hizmet süresi boyunca, bakım, onarım ve rehabilitasyon planlaması 30 yıllık analiz periyoduna göre gerçekleştirilmiştir. İlk inşaat maliyeti açısından SSB yolun, asfalt yoldan %39,4 daha ekonomik olduğu ve servis süresi boyunca da %62 oranında bakım ve onarım ekonomisi sağladığı tespit edilmiştir. Yaşam döngüsü maliyetleri açısından ise SSB yolun asfalt yoldan %46 daha ekonomik bir kaplama tercihi olabileceği belirlenmiştir. Bu durumun ortaya çıkmasında, ilk ciddi onarım faaliyetinin asfaltta 10. ve 20. yılda yapılmasına karşın, SSB kaplamada bu faaliyetin sadece 20. yılda gerçekleşmesi ve asfalt bakım malzemesinin SSB bakım malzemesinden daha pahalı olması etkili olmuştur.
