Use of recycled/reclaimed asphalt pavement (RAP) leads to economic as well as environmental benefits. However, increasing the percentage of RAP in a new asphalt pavement may hinder the economic benefits due to the necessity of expensive softer binders used to compensate for RAP stiffening effect. Alternatively, this problem may potentially be overcome by use of another recycled material: crumb rubber (CR). In this study, linear viscoelastic, thermal and fatigue cracking properties of mixtures… 
Effect of Addition of Dry Crumb Rubber on the Performance of Terminal Blend Crumb Rubber Modified Asphalt Mixtures
Three major methods are used to produce crumb rubber modified asphalt pavement: the dry process (CRDry), the terminal blend process (CRTB), and the wet process (CRWet). Although the CRDry process
Performance of High Content Reclaimed Asphalt Pavement (RAP) in Asphaltic Mix with Crumb Rubber Modifier and Waste Engine Oil as Rejuvenator
The utilisation of reclaimed asphalt pavement (RAP) as a suitable substitute for natural aggregate and binder offers an energy-saving and cost-effective approach to enhance the performance of asphalt
Analysis of the Influence of Production Method, Crumb Rubber Content and Stabilizer on the Performance of Asphalt Rubber
Asphalt rubber (AR) is often described as an environmentally friendly material due to the incorporation of recycled rubber from used tires and its improved service life. Its field application is
Life Cycle Risk Assessment Applied to Gaseous Emissions from Crumb Rubber Asphalt Pavement Construction
Asphalt mixtures for road pavements are produced and laid at high temperatures, producing gaseous emissions that contain polycyclic aromatic hydrocarbons and volatile organic compounds that paving
Estimation and Analysis of Energy Conservation and Emissions Reduction Effects of Warm-Mix Crumb Rubber-Modified Asphalts during Construction Period
In order to solve the serious environmental problems caused by the rapid increase in the number of waste tires and unproper storage of waste tires, modifying the asphalt mix for roadway pavement by


Can More Reclaimed Asphalt Pavement be Added?
Results of a study conducted by the New Hampshire Department of Transportation (NHDOT) in cooperation with three local paving contractors are presented. Plant-produced hot-mix asphalt (HMA) mixtures
Reclaimed Asphalt Pavement in Asphalt Mixtures: State of the Practice
FOREWORD Recycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources. Reclaimed asphalt pavement (RAP) is a useful alternative to virgin materials
A Fracture Energy Approach to Model the Thermal Cracking Performance of Asphalt Rubber Mixtures
ABSTRACT The existing Thermal Cracking Model (TCMODEL) that is currently an integral part of the Mechanistic Empirical Pavement Design Guide (MEPDG) has been shown to adequately predict low
Feasibility of using high RAP contents in hot mix asphalt
Reclaimed or recycled asphalt pavement (RAP) consists of milled or excavated asphalt pavement which is crushed and screened into different sizes to meet specified grading requirements. RAP can be
Factors Study in Low-Temperature Fracture Resistance of Asphalt Concrete
An investigation of various factors that can affect the fracture resistance of asphalt mixtures at low temperatures was conducted. The fracture resistance of 28 asphalt mixtures—which represent a
Use of Small Samples to Predict Fatigue Lives of Field Cores
Fatigue cracking is one of the major distresses in asphalt pavements. Accurate prediction of fatigue life of asphalt pavements can be extremely important both during the design stage and for
Conventional and Viscoelastic Continuum Damage (VECD)-Based Fatigue Analysis of Polymer Modified Asphalt Pavements (With Discussion)
Asphalt mixture fatigue performance is crucial for flexible pavement design. Important sources of information for field fatigue life prediction are laboratory fatigue characterization tests. In this
Use of fracture work density obtained from indirect tensile testing for the mix design and development of a fatigue model
Bottom-up fatigue cracking, which is a major distress in asphalt pavements, is due to repeated traffic loading that induces tensile stress in the asphalt concrete layers. Fatigue cracks are observed
This report presents the findings of a research project to evaluate the use of the indirect tensile creep and strength test procedures in AASHTO Standard Method of Test T322-03 in mixture and
