Beton Yol Kaplamalarının Yüzey Sıcaklıklarının Düşürülmesi için Çözümler

Beton plak yüzey sıcaklık farkındaki artış, beton yollarda yüksek oranda çatlamaları tetiklemektedir. Bu çalışmanın öncelikli amacı, ince agrega yerine cam, çimento yerine de zeolit kullanarak plak yüzey sıcaklığını düşürmektir. Bu amaçla 10 değişik beton karışım hazırlanmıştır. Numunelerin mekanik özellikleri ve alkalisilika reaksiyonları (ASR) incelenerek en uygun karışım oranları belirlenmiştir. 3 farklı karışımdaki beton plakların yazın gün içindeki yüzey sıcaklıkları ölçülmüştür. Betonda, cam ve zeolitin birlikte kullanımının kaplama üst yüzey sıcaklığını düşürdüğü tespit edilmiştir

Solutions for Reducing the Surface Temperatures of Concrete Pavements

The increased concrete slab surface temperature difference induces a high possibility of cracking in concrete roads. The prime aim of this study was to reduce the slab surface temperature by using glass as a fine aggregate and zeolite as a cement in concrete. 10 different concrete mixtures were prepared for this purpose. Optimum mixture proportions were determined by examining mechanical properties and alkali-silica reactions (ASR) of samples. The surface temperatures of 3 concrete slabs with different mixtures were measured during the day in summer. It was noticed that using glass and zeolite together in concrete reduces pavement surface temperature
