Stability of Asphaltic Concrete Mixtures

1989
This study was initiated with the general objective of quantifying some of the parameters that govern the stability and rutting characteristics of asphalt-bound materials. Aggregate type and gradation, loading magnitudes and patterns asphalt types and viscosity, are known to affect the stability of an asphalt mixture.

Performance Evaluation of Asphalt Rubber in Porous Asphalt-Concrete Mixtures

Journal of Materials in Civil Engineering, 2011
The purpose of this study was first to present the laboratory mix design results for porous asphalt concrete (PAC) mixtures blended with high-viscosity-graded cement (AR-80) and asphalt rubber (AR). In addition, the master curves of dynamic modulus were determined for both the unconfined and confined conditions to evaluate the rutting behavior of both ...

Coal Ash Utilization in Asphalt Concrete Mixtures

Journal of Materials in Civil Engineering, 1999
Dwindling supplies and rising costs of natural resources used in road construction as well as concerns over shrinking landfill spaces prompt researchers to investigate the use of waste products, such as coal ash, as substitute materials in highway construction.

Characterization of Microdamage and Healing of Asphalt Concrete Mixtures

Journal of Materials in Civil Engineering, 2002
The pseudo-strain concept based on Schapery’s extended nonlinear elastic-viscoelastic correspondence principle is demonstrated by a considerable database to be able to characterize both microdamage and microdamage healing during the damage process. A change in pseudo stiffness can be used to quantify microdamage and healing during the fatigue test ...

Evaluation of Polymer-Modified Asphalt Concrete Mixtures

Journal of Materials in Civil Engineering, 1995
Since the mid-1980s, polymer-modified asphalt concrete mixtures have been widely used to minimize rutting failures of flexible pavements. This research investigates the permanent deformation behavior of unmodified asphalt concrete mixtures as compared to the behavior of asphalt concrete mixtures modified with polyethylene.

Engineering Properties of Asphalt Concrete Patching Mixtures

Journal of Testing and Evaluation, 2016
Abstract Potholes are a visible and annoying form of pavement distress for highway users. One reason for the short life of pothole repairs is that the commonly used patching mixtures cannot withstand the wet weather and the traffic loading.

Behavior of Asphalt Concrete Mixtures in Triaxial Compression

Journal of Testing and Evaluation, 1994
Abstract The triaxial compression test is one of the most common standard tests for determining the stress-strain behavior and strength parameters of soils under drained and undrained conditions. The use of the test method in asphaltic mixtures is less well known and seldom practiced.

Evaluation of asphalt concrete mixtures for railway track

Construction and Building Materials, 2014
Abstract In this study, the performance of three asphalt concrete mixtures for railway track using three different asphalt binders which are PG64-22, crumb rubber modified (CRM) asphalt binder, and styrene–butadiene–styrene (SBS) modified asphalt binder was investigated in terms of moisture susceptibility, permanent deformation, and fatigue cracking ...

Rutting Resistance of Asphalt Concrete Mixtures that Contain Recycled Asphalt Pavement

Transportation Research Record: Journal of the Transportation Research Board, 2011
This study evaluated the rutting resistance of plant-produced asphalt concrete (AC) mixtures in the laboratory. Nineteen plant-produced AC mixtures were used; these mixtures contained reclaimed asphalt pavement (RAP) amounts that ranged from 0% to 25%. Tests on the mixtures included the dynamic modulus (|E *
