Development of an asphalt concrete mixture for Asphalt Core Rockfill Dam
Construction and Building Materials, 2017Abstract The main objective of this paper is to develop asphalt concrete mixture and conduct performance tests for Asphalt Core Rockfill Dam (ACRD). Three conditions of mineral filler content have been used: 10, 12 and 14%, namely: F10, F12 and F14 respectively.

Modified asphalt concrete mixtures and asphalt concrete for the needs of Odesa region
Theory and Building PracticeThe article examines the effect of Ukrainian-produced petroleum road bitumen BND 70/100 from Kremenchuk Oil Refinery modified separately with polymers, synthetic waxes, and adhesion additives on dense asphalt concrete type A, grade 1. Nine additives were studied: polymers (Calprene 501, PDL S501T SBS, Elvaloy 741, Kraton D1101 ASM), waxes (Asphalten A,

Performance Evaluation of Asphalt Rubber in Porous Asphalt-Concrete Mixtures
Journal of Materials in Civil Engineering, 2011The 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 ...

Evaluation of Asphalt Concrete Mixtures for Railway Track
Construction and Building Materials, 2014Abstract 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 ...

Coal Ash Utilization in Asphalt Concrete Mixtures
Journal of Materials in Civil Engineering, 1999Dwindling 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, 2002The 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, 1995Since 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, 2016Abstract 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.

Effects of Fillers on Properties of Asphalt-Concrete Mixture
Journal of Transportation Engineering, 2012The role of filler on the mechanical performance of asphalt-concrete mixture was investigated. Three wearing course (W3B) mixtures incorporating granite, hydrated lime, and kaolin as filler fractions were evaluated by the Marshall mix design method to determine their optimum asphalt content.

Behavior of Asphalt Concrete Mixtures in Triaxial Compression
Journal of Testing and Evaluation, 1994Abstract 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.
