Polymer-Modified Bio-Asphalt: A Sustainable Panacea to Greenhouse Gas Emissions

Abstract

L'industrie de l'asphalte a été perpétuellement confrontée à ses problèmes d'émissions dangereuses pour la santé et de réchauffement climatique, en particulier lorsqu'elle est produite avec ou à partir de dérivés de combustibles fossiles et avec la nécessité d'une résistance plus élevée pour répondre aux charges par essieu des camions lourds sur les autoroutes. Compte tenu de l'augmentation constante de l'intensité du trafic des camions lourdement chargés et de l'augmentation de la surcharge des essieux des camions ainsi que de la variation significative de la température quotidienne et saisonnière en raison des effets du changement climatique, il est essentiel de modifier le ciment asphaltique conventionnel en utilisant une combinaison de modificateurs pour améliorer les propriétés techniques des mélanges afin de répondre à la complexité des facteurs de résistance plus élevée et de l'environnement.Le réchauffement climatique a donc énormément contribué aux effets néfastes du changement climatique, à la dégradation de l'environnement et aux problèmes de santé humaine qui en découlent.Les défis posés par la pollution mondiale et l'épuisement des combustibles fossiles entraînant un coût élevé des dérivés liants bitumineux tels que le bitume ont motivé la recherche, le développement et l'utilisation de liants alternatifs, parmi lesquels le bitume modifié par des polymères et les bio-huiles.Recherche dans cette direction espère trouver un remplacement permanent du bitume, réduisant ainsi les émissions de gaz à effet de serre et les effets du changement climatique qui en découlent.

La industria del asfalto se ha visto constantemente desafiada por sus emisiones peligrosas para la salud y los problemas de calentamiento global, especialmente cuando se produce con o a partir de derivados de combustibles fósiles y junto con la necesidad de una mayor resistencia para satisfacer las cargas de los ejes de los camiones pesados en las carreteras. En vista del aumento constante de la alta intensidad de tráfico de los camiones muy cargados y el aumento de la sobrecarga de los ejes de los camiones, junto con la variación significativa de la temperatura diaria y estacional debido a los efectos del cambio climático, es esencial modificar el cemento asfáltico convencional utilizando una combinación de modificadores para mejorar las propiedades de ingeniería de las mezclas para cumplir con la complejidad de los factores de mayor resistencia y el medio ambiente. El calentamiento global ha contribuido enormemente a los efectos adversos del cambio climático, la degradación ambiental y los problemas de salud humana concomitantes. Los desafíos planteados por la contaminación global y el agotamiento de los combustibles fósiles que conducen a un alto costo de los derivados de aglutinantes bituminosos como el betún han motivado la búsqueda, el desarrollo y la utilización de aglutinantes alternativos, entre los que se encuentran el betún modificado con polímeros y los bioaceites. La investigación en esta dirección espera encontrar un reemplazo permanente para el betún, reduciendo así las emisiones de gases de efecto invernadero y los efectos del cambio climático.

The asphalt industry has been perpetually challenged with its health hazardous emissions and global warming issues, especially when produced with or from derivatives of fossil fuels and together with the need for higher strength to meet the heavy truck axle loads on highways.In view of the steady increase in high traffic intensity of heavily loaded trucks and the increase in the overloading of truck axles together with the significant variation in daily and seasonal temperature due to climate change effects, it is essential to modify the conventional asphalt cement using a combination of modifiers to improve the engineering properties of mixes to meet the complexity of the factors for higher strength and the environment.Global warming has consequently contributed immensely to adverse climate change effects, environmental degradation and attendant human health problems.The challenges posed by global pollution and depletion of fossil fuels leading to high cost of bituminous binder derivatives such as bitumen have motivated the search for and development and utilization of alternative binders, amongst which are polymer-modified bitumen and bio-oils.Research in this direction is hoping to find a permanent replacement for bitumen, thereby reducing greenhouse gas emissions and attendant climate change effects.

واجهت صناعة الأسفلت تحديًا دائمًا بسبب انبعاثاتها الخطرة على الصحة وقضايا الاحتباس الحراري، خاصة عند إنتاجها مع أو من مشتقات الوقود الأحفوري ومع الحاجة إلى قوة أعلى لتلبية أحمال محور الشاحنة الثقيلة على الطرق السريعة. في ضوء الزيادة المطردة في الكثافة المرورية العالية للشاحنات المحملة بكثافة والزيادة في التحميل الزائد لمحاور الشاحنات مع التباين الكبير في درجة الحرارة اليومية والموسمية بسبب تأثيرات تغير المناخ، من الضروري تعديل الأسمنت الإسفلتي التقليدي باستخدام مجموعة من المعدلات لتحسين الخصائص الهندسية للخلطات لتلبية تعقيد عوامل القوة العالية والبيئة. وبالتالي، ساهم الاحترار العالمي بشكل كبير في التأثيرات الضارة لتغير المناخ والتدهور البيئي والمشاكل المصاحبة لصحة الإنسان. وقد حفزت التحديات التي يفرضها التلوث العالمي واستنفاد الوقود الأحفوري مما أدى إلى ارتفاع تكلفة مشتقات رابطة البيتومين مثل البيتومين البحث عن مواد رابطة بديلة وتطويرها واستخدامها، من بينها البيتومين المعدل بالبوليمر والزيوت الحيوية. الأبحاث في هذا الاتجاه، نأمل في إيجاد بديل دائم للبيتومين، وبالتالي تقليل انبعاثات غازات الدفيئة وما يصاحبها من آثار تغير المناخ.
