Asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. This is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. This paper presents the evaluation of fatigue behaviour of nano reinforced Stone Mastic Asphalt mixtures. Fatigue...

16. Abstract Pavement structures are designed for a finite life, usually referred to as performance period. This performance period is typically between 20 to 25 years for flexible pavements and between 25 and 40 years for rigid pavements. After this period, the pavement is predicted to reach a terminal level in terms of several preset criteria. This performance period can be reached by designi...

The paper presents results of sensitivity analysis to crack propagation of a pavement bituminous layered structure using the Finite Element Method (FEM) and Artificial Neural Networks (ANN). The performed preliminary study determined stresses and displacements in the pavement layer system. The pavement structure consisting of asphalt layers, a base layer, subbase and subgrade layers was analyze...

Pavement rutting is one of the most common and destructive pavement distresses being observed in flexible pavements, which is primarily due to axle loads that exceed legal limit and high ambient temperatures, and also poor mix design is one of the cause of rutting. The drastic increase in traffic volume during last few decades has resulted in premature pavement failures of almost the whole road...
