Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures
Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...
متن کاملPerformance Evaluation of Dynamic Modulus Predictive Models for Asphalt Mixtures
Dynamic modulus characterizes the viscoelastic behavior of asphalt materials and is the most important input parameter for design and rehabilitation of flexible pavements using Mechanistic–Empirical Pavement Design Guide (MEPDG). Laboratory determination of dynamic modulus is very expensive and time consuming. To overcome this challenge, several predictive models were developed to determine dyn...
متن کاملEvaluation of Long-Term Field Performance of Cold In-Place Recycled Roads
Cold in-place recycling (CIR) has become an attractive method for rehabilitating asphalt roads that have good subgrade support and are suffering distress related to nonstructural aging and cracking of the pavement layer. Although CIR is widely used, its use could be expanded if its performance were more predictable. Transportation officials have observed roads that were recycled under similar c...
متن کاملToughness Performance of Recycled Aggregates for use in Road Pavement
The policy of driving organization such as Highways Agency is towards the use of performance related specifications. This policy and adoption of European wide aggregate standards on the one hand, and sustainable construction pressures on the other, all strongly emphasize on further need for more developments to specifications and performance assessment methodologies inst...
متن کاملModeling of Resilient Modulus of Asphalt Concrete Containing Reclaimed Asphalt Pavement using Feed-Forward and Generalized Regression Neural Networks
Reclaimed asphalt pavement (RAP) is one of the waste materials that highway agencies promote to use in new construction or rehabilitation of highways pavement. Since the use of RAP can affect the resilient modulus and other structural properties of flexible pavement layers, this paper aims to employ two different artificial neural network (ANN) models for modeling and evaluating the effects of ...
