“…Chemical WMA additive is an established additive that is currently being used by the asphalt industry as a modifier in the manufacture of WMA mixtures. The physical and chemical properties of unmodified and modified asphalt binders have been discussed previously in [23] and will not be discussed here for the sake of brevity.…”

“…Nanokil, bitümün ve asfalt karışımların mühendislik özelliklerinin iyileştirilmesinde önemli etkiye sahiptir. Bu malzemeler, SBS-modifiye bağlayıcının performans özelliklerini daha da geliştirmek için ikincil modifiye edici katkı olarak kullanılabilmektedir [40]. Sıcak karışım asfaltlarda, filler olarak toplam karışım ağırlığına oranla %2, %3,5 ve %5 dozajlarında nanokil kullanılan çalışmada, performans karakteristikleri; nem duyarlılığı, dolaylı çekme mukavemeti, tekrarlı sünme ve modifiye Lottman testleri ile incelenmiş, %2 oranında nanokil içeren karışımın en iyi performansa sahip olduğu belirlenmiştir [10].…”

Asfalt karışımlarda temel bozulma problemlerinin en aza indirgenmesi ve performans artışı sağlanabilmesi için çeşitli katkı maddeler kullanılabilmektedir. Bu katkı maddeleri arasında stiren-bütadiyen-stiren (SBS) katkısı en çok tercih edilen katkılar arasındadır. SBS’in asfalt çimentosu ve asfalt karışımın performansını önemli oranda arttırdığı bilinmektedir. Ancak yüksek maliyeti ve bitüm ile olan zayıf uyumu nedeniyle kullanımında sorunlar yaşanabilmektedir. Nanokil polimerlerle birlikte kullanılarak onların özelliklerini arttırabilmektedir. Bu çalışmada, farklı SBS oranlarında (%5, %4, %3, %2 ve %1) sabit %2 ve %3 nanokil ilavesinin etkisi su hasarı, tekerlek izi ve çatlama direnci yönüyle irdelenmiş, SBS oranının azaltılabilirliği sorgulanmıştır. Test sonuçlarına göre, %2nanokil-%3SBS oranının memnun edici sonuçlar verdiği görülmüştür.

“…Viscosity grading is related to the consistency of the binder at a specific temperature and not directly related to its performance throughout the anticipated life of the pavement. As a result, it does not mandate for viscosity measurements and therefore, it is difficult to set up the correct HAM [7]. On the other hand, in recent years, the Strategic Research Programs in High Technology (SHRP) has developed new criteria for the selection of asphalt binder, known as a Performance Grade system (PG), to overcome certain limitations.…”

Libya use a volumetric analysis in designing asphalt mixtures, which can also be upgraded in hot weather. However, the condition of some roads was further down than the required level. Rutting is one of the major defects that occur in asphalt pavements in the southern desert of Libya and severely influence the drive-ability. A questionnaire surveys and laboratory experiments were performed for a few mixes under representative temperature and traffic load. In laboratory, rutting test conducted on two different asphalt mixtures. The first mix used an asphalt binder B (60/70) at optimum bitumen content, another mixture developed using the Superpave design procedure with the same materials and performance asphalt binder grade PG (70-10). The questionnaire survey was distributed to 55 engineers and specialists in the field. The interview was conducted to a few others and the factors that leading to poor performance of asphalt roads were listed. Considering and improving of these factors will play an important role to improve the pavement performances, longer service life and lower maintenance costs. Asphalt concrete pavements (ACP) should use asphalt binder which is less affected by pavement temperature change and traffic load. The properties of the mixture, in turn, affect the pavement performance. Keywords - asphalt mixtures, consistency, performance, (PG), construction.
