This report presents the results of an investigation of the performance of a variety of materials added to asphalt binders and mixtures to change their properties, particularly with respect to rutting and cracking. The approach included a field trial of seven polymer and particulate modifiers, supplemented by laboratory characterization of the materials used in the field.

12/10/2019 and Asphalt Pavement Analyser (APA) tests. The results revealed that 0.4 % ET and 0.3 % EF additives were considered as optimum additive content. Both 0.4 % ET and 0.3 % EF gave better performance in stripping and rutting resistance. However, in cracking performance, 0.4 % ET was more susceptible in cracking compared with 0.3 % EF. 1.

cracking on hot-mix asphalt (HMA) pavements, various new HMA mix-designs are being explored in the State of Texas [1-4]. For example, over the past few years, there has been a high interest in using rich asphalt-binder and high quality fine-graded aggregate mixes such as crack attenuating mixtures (CAM) that provide improved resistance to cracking [1, 2] as compared to traditional Texas dense ...

Another cause of rutting for asphalt roads is a poor asphalt mix. What really happens when a car drives over a road that is forming rutting is the mix lacks the internal strength to resist permanently deforming under the stress imposed by the loaded vehicle tires (Under). Rutting usually does not occur immediately, but as more cars drive over the asphalt, the asphalt continues to get depressed ...

Cost-effective additive improves strength, reduces rutting and cracking Gilsonite® has been used as an additive to enhance the performance of asphalt pavements for more than 100 years. While field experience had demonstrated the advantages of using Gilsonite, the unique properties of Gilsonite-modified asphalt had not been well-documented due to the lack of a comprehensive evaluation.

Distortions in an asphalt pavement are caused by instability of an asphalt mix or weakness of the base or subgrade layers. These distresses may include rutting, shoving, depressions, swelling and patch failures. Rutting. Rutting is a linear, surface depression in the wheelpath. Rutting is caused by deformation or consolidation of any of the ...

In a balanced mix design framework, a performance diagram can be a useful tool to examine the balance between the rutting and cracking susceptibility of an asphalt mixture. Using such a diagram, a cracking parameter is plotted against a rutting parameter to assess the interaction between the two as the asphalt content of the mix (or other mix variable) is changed. In this case, the I-FIT ...
