Macro-encapsulated phase change material (PCM) lightweight aggregates (ME-LWA) were produced and evaluated for their mechanical and thermal properties in road engineering applications. The ME-LWAs were first characterised in terms of their physical and geometrical properties. Then, the ME-LWAs were investigated in detail by applying the European Standards of testing for the Bulk Crushing Test and the Polished Stone Value (PSV) coefficient as well as Micro-Deval and laboratory profilometry. In addition, the thermal performance for possible construction of smart pavements with the inclusion of ME-LWAs for anti-ice purposes was determined. The crushing resistance of the ME-LWAs was improved, while their resistance to polishing was reduced. Thermal analysis of the encapsulated PCM determined it to possess excellent thermal stability and a heat storage capacity of 30.43 J/g. Based on the research findings, the inclusion of ME-LWAs in surface pavement layers could be considered a viable solution for the control of surface temperatures in cold climates. Road safety and maintenance could benefit in terms of reduced ice periods and reduced treatments with salts and other anti-ice solutions.

Steelmaking industries produce a large amount of solid wastes that need to be adequately managed in order to ensure environmental sustainability and reduce the impact of their disposal on earth pollution. Electric arc furnace (EAF) slags are those wastes deriving from secondary steelmaking production; these slags can be re-used and recycled in many industrial applications such as the production of asphalt mixes. In this paper authors investigate the surface performance of EAF slags used as second-hand aggregate in asphalt mixes. In particular, slags behavior under polishing is compared to other types of aggregate commonly used for asphalt concrete such as limestone, basalt, and kinginzite. Several devices (skid tester, laser profilometer, polishing machine) were used to collect experimental data; the analysis of microtexture was carried out by comparing aggregate surface performance before and after polishing. Results show that EAF slags are positively comparable to basalt as concerns the polishing behavior; good correlations between skid resistance and some microtexture indicators are also carried out.

“…Sathi kaplamalar yüzeye önce bağlayıcının püskürtülmesi ve ardından mıcırın serilmesi ve sıkıştırılması ile imal edilirken, harç tipi kaplamalar belirli miktarda agreganın ve bitümün karıştırılması ve serilmesi ile üretilmektedir. Genel olarak, sathi veya harç tipi kaplamalar, diğer kaplama koruma ve iyileştirme yöntemleriyle karşılaştırıldığında efektif, ekonomik ve kolay uygulanabilir olmaları nedeniyle genel olarak tercih edilmektedir [15,16]. Yüzeysel kaplamaların performansı yapım şartları, malzeme özellikleri ve miktarları, trafik, hava ve çevre koşulları gibi bir takım faktörlere bağlıdır [35].…”

ÖzBu çalışmada, doğal agregalardan ve cüruflardan oluşan farklı agrega tür ve tane boyutlarında ve gradasyonunda üretilen yüzeysel kaplamaların kayma direnci performansı araştırılmıştır. Bu amaç doğrultusunda, öncelikle her bir agreganın fiziksel, mekanik ve kimyasal özelikleri TS EN standartlarına göre belirlenmiştir. Sathi kaplama örnekleri; 2-19 mm aralığında değişen yedi farklı tane boyutunda hazırlanırken, harç tipi kaplama örnekleri ise üç farklı gradasyonda üretilmiştir. Üretilen yüzeysel kaplama numunelerinin, kayma dirençleri ve makro dokuları sırasıyla ASTM E 303 ve ASTM E 965 standartları göre belirlenmiştir. Yüzeysel kaplamaların kayma direnci karşılaştırıldığında, her boyut ve gradasyonda cüruflar ile üretilmiş olan numunelerin, doğal agrega ile üretilmiş olan numunelerden daha iyi performans gösterdiği gözlenmiştir.Anahtar Kelimeler: Kayma direnci, Yüzeysel kaplamalar, Kaplama dokusu, Cüruf Evaluation of Skid Resistance Perfromance of Surface Coatings Manufactured with Different Aggregates AbstractIn this study, skid resistance performance of surface coatings, which were produced with different aggregate types including natural aggregates and slags and sizes and gradations were evaluated. Physical, mechanical and chemical properties of each aggregate were determined according to related EN standards. Chip seal samples were prepared with seven different particle size ranging from 2.00 to 19.00 mm, whereas slurry seal samples were manufactured in three different gradations, which are specified in ASTM D 3910. To identify the skid resistances and macro-textures of each surface coating samples, ASTM E 303 and ASTM E 965 were followed. The results showed that skid resistance performance of the samples manufactured with slags higher that those produce with natural aggregates.
