Case study of rutting performance of HMA modified with waste rubber powder
TLDR
In this paper, the effect of adding waste rubber powder on the rutting performance of asphalt mixtures has been studied and the results show that the use of rubber powder caused a significant decrease in the rate of rutts depth of rubber asphalt mixture compared to control samples.About:

Recycling of waste tire rubber: Microwave devulcanization and incorporation in a thermoset resin.
TL;DR: It appeared that epoxy composites filled with DGTR have better mechanical properties than those filled with untreated GTR, which agrees with scanning electron microscopy observations which highlighted a better interface coherence between DGTR and epoxy.

Usage of two biomass ashes as filler in hot mix asphalt
TL;DR: In this paper, the authors investigated the potential of using two biomass ashes, which are agricultural waste/byproducts namely rice husk ash (RHA) and date seed ash (DSA), as filler material in hot mix asphalt by replacing conventional filler at different percentages.

Using the visual intervention influence of pavement marking for rutting mitigation – Part II: visual intervention timing based on the finite element simulation
TL;DR: In this paper, visual intervention has a significant influence on drivers' behavior, which may cause the redistribution of wheel tracks, relieving the stress from the concentration of axial loads so that the rut...

Determination of the optimum conditions for tire rubber in asphalt concrete
TL;DR: In this article, the Taguchi method was used to determine optimum conditions for tire rubber in asphalt concrete with Marshall Test, and the optimum conditions were obtained for the following parameters: tire rubber gradation (sieve #40), mixing temperature (155,°C), aggregate gradient (grad. 1), tire rubber ratio (10%), binder ratio (5.5%), compaction temperature (135,°C) and mixing time (15,min).

Waste materials in hot mix asphalt - an overview
TL;DR: The hot mix asphalt (HMA) industry has been pressured in recent years to incorporate a wide variety of waste materials into HMA pavements as discussed by the authors, which has raised the following legitimate concerns: (a) engineering concerns such as effect on the engineering properties (for example, strength and durability), impact on production, and future recyclability; (b) environmental concerns such, emissions, fumes, odor, leaching, and handling and processing procedures; and (c) economic concerns such including life cycle costs, salvage value, and lack of monetary incentives.

Permanent deformation properties of asphalt concrete mixtures
TL;DR: Rutting is recognized to be the major distress mechanism in flexible pavements as a result of increase in tire pressures and axle loads as discussed by the authors. Rutting is caused by the accumulation of permanent deformati...
