The micromechanical load transfer and failure of asphalt concrete samples are simulated using a finite element network model. The load carrying behavior of such a material is strongly related to the local load transfer between aggregate particles, and this is taken as the microstructural response. The model incorporates a network of special frame elements with a stiffness matrix developed to pr...

Today, rapid economic and industrial growth generates increasing amounts of waste materials such as waste tyre rubber. Attempts to inspire a green technology which is more environmentally friendly that can produce economic value are a major consideration in the utilization of waste materials. The aim of this study is to evaluate the effect of waste tyre rubber (crumb rubber modifier (CRM)), in ...

The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...

Hỗn hợp Stone Matrix Asphalt (SMA) là một loại bê tông asphalt tính năng cao được sử dụng cho những kết cấu mặt đường thường xuyên chịu tải trọng xe nặng hay sân bay. Do SMA có trúc tiếp xúc đá chèn và thành phần phụ gia ổn định nên sức kháng hằn lún vệt bánh của hỗn tăng lên. Có nhiều theo cách khác nhau, mỗi sẽ các ngắn hạn cũng như dài nhau. Bài báo này đưa ra quả thực nghiệm đánh giá đặc nứ...
