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 ...

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 ...

Stability of Asphaltic Concrete Mixtures
1989This 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.

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.

Placement of Asphalt Concrete Mixtures
1984A 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.

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.

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.
