IMPROVING THE PERFORMANCE CHARACTERISTICS OF ASPHALT CONCRETE BY REINFORCING ASPHALT CONCRETE MIXTURES SYNTHETIC FIBERS

Automobile Roads and Road Construction, 2023
This article shows that one of the reasons for the deterioration of the condition of highways is largely the mismatch of the operational characteristics of road construction materials with increased traffic loads. The rapid increase in the number of heavy trucks on the roads, the increase in traffic intensity and, as a result, the increase in axial ...

Utilization of Gneiss in Asphalt Concrete Mixtures

Materials Science Forum, 2009
Construction of the pavement has consumed a huge amount of high grade aggregates, such as basalt, limestone etc. In some region, these aggregates are very scarce and have to be produced and transported from far aggregate quarries which would cause the waste of energy and resources as well as the increase of cost.

Placement of Asphalt Concrete Mixtures

1984
A brief description of the history of the development of the asphalt paver is given in this paper. It discusses the principle of the floating screed and the operation of the paver tractor unit and screed unit. The forces that act on the screed and keep it in balance (level) to provide a smooth asphalt concrete mat are explained.

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.
