Evaluation of Recycled Asphalt Shingles in Hot Mix Asphalt
Transportation and Development Institute Congress 2011, 2011The objective of this study was to evaluate the performance of asphalt mixtures containing different dosages of recycled asphalt shingles (RAS) using the dynamic modulus (|E*|) test with a universal testing machine and rutting test with the asphalt pavement analyzer (APA). In this study, 5% and 10% RAS were used in the Superpave mixtures.

Effects of Reclaimed Asphalt Pavement on Hot-mix Asphalt
Advances in Civil Engineering Materials, 2014Abstract This study examined the effects of reclaimed asphalt pavement (RAP) on the structural properties and performance of hot-mix asphalt (HMA) and the rheological properties of asphalt binder in the laboratory. As a first step, dynamic modulus (|E*|) and indirect tensile strength (ITS) tests were conducted on a set of HMA samples ...

Characterization of Recycled Asphalt Pavement Materials for Use in Hot-Mix Asphalt Mixes
Journal of Testing and Evaluation, 2023ABSTRACT The use of recycled asphalt pavements (RAPs) has been a common practice in recent times owing to the sustainability aspect as well as the cost savings. Characterization of RAP is a challenging task because of the high variability in RAP, which can be associated with several factors such as the source, milling method, and ...

Low-Energy Asphalt with Performance of Hot-Mix Asphalt
Transportation Research Record: Journal of the Transportation Research Board, 2006The paper presents an original process to produce a warm asphalt mixture: low-energy asphalt (LEA) with the performance of hot-mixasphalt(HMA). The Kyoto agreements continue to divide the planet, while protocol signatories are defining their application conditions.

Detection of Stripping in Hot-Mix Asphalt
Transportation Research Record: Journal of the Transportation Research Board, 2006Damage mechanisms that lead to stripping significantly affect the dynamic modulus and tensile strength of hot-mix asphalt (HMA). When stripped HMA is unexpectedly encountered below the planned milling depth during routine mill and overlay rehabilitation projects, it must be removed and replaced; this causes significant cost overruns and delays.

Microstructure Index of Hot Mix Asphalt
Road Materials and New Innovations in Pavement Engineering, 2011Digital image processing technique is used to quantify the impact of aggregate gradation and compaction method on air voids distribution and aggregate orientation and distribution. The air voids distribution was found to be sensitive to water permeability than traditional volume indexes.

Hot mix asphalt recycling has become common practice all over the world since the 1970s because of the crisis in oil prices. In the Netherlands, hot recycling has advanced to such an extent that in most of the mixtures more than 50% of reclaimed asphalt (RA) is allowed. These mixtures with such a high RA content are produced in a batch plant to which a

Determination of Lime in Hot-Mix Asphalt
Transportation Research Record: Journal of the Transportation Research Board, 2006Lime is added to hot-mix asphalt to mitigate stripping and other modes of moisture damage. No standard forensic test exists for the measurement of the lime content after it has been incorporated in the asphalt. This paper evaluates several methods to quantify the amount of hydrated lime (calcium hydroxide) in asphalt.

Micromechanical Simulation of Hot Mix Asphalt
Journal of Engineering Mechanics, 1997A model based on the discrete element method (DEM), ASBAL, was developed by modifying the TRUBAL program to simulate hot mix asphalt (HMA). To represent asphalt cement, several viscoelastic elements (i.e., Maxwell, Kelvin-Voigt, and Burger's elements) were considered. The research results from the Strategic Highway Research Program (SHRP) were used for

Bimodular Analysis of Hot-Mix Asphalt
Road Materials and Pavement Design, 2010In this paper, the bimodular (different tensile and compressive moduli) stress distribution in the IDT specimen is determined for different compressive to tensile modulus ratios. The difference between the modulus calculated from the IDT test assuming Hondros' linear elastic stress distribution, and the compressive and tensile moduli is then obtained ...
