BETON YOL KAPLAMALARININ YÜZEY SICAKLIKLARININ DÜŞÜRÜLMESİ İÇİN 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 düşürmekti. Bu çalışmada cam, toplam agrega ağırlığının 10%, 20% ve 30% oranlarında kullanılmış, zeolit ise 10% ve 30% oranlarında çimento yerine kullanılmıştır. Numunelerin mekanik özellikleri ve alkali-silika reaksiyonları (ASR) incelenerek en uygun oranlar belirlenmiştir. Betonda cam ve zeolitin birlikte kullanımının kaplama yüzey sıcaklığını ve üst yüzeyle alt yüzey arasındaki sıcaklık farkını düşürdüğü tespit edilmiştir.

Anahtar Kelimeler:

beton yol, cam; zeolit; ısıl çatlak
