  This research evaluates the effect of recycled polyethylene terephthalate (PET) fibers on the fatigue properties of hot asphalt mix. Based on micro-structural analysis, fiber contents were taken into account as equal to (i.e. reference mix), , , and % by weight of bitumen. HMAC mixtures were fabricated from materials used on three different road sections in Texas and one test pavement in Minnesota. The CMSE approach was validated as an effective approach for estimating the fatigue resistance of HMAC mixtures with PMA. The effect of oxidative aging on the fatigue resistance of the HMAC mixtures was also verified.

This report evaluates test procedures for measuring the fatigue response of asphalt paving mixtures, and summarizes current knowledge of the factors that influence fatigue response. Available test methods are classified, and criteria used to evaluate each method for its potential use as a laboratory standard are discussed.

Summary: This report evaluates test procedures for measuring the fatigue response of asphalt paving mixtures, and summarizes current knowledge of the factors that influence fatigue response. Available test methods are classified, and criteria used to evaluate each method for its potential use as a laboratory standard are discussed.

This summary report, focussing on the fatigue response of asphalt mixtures, is one of a series prepared as a part of SHRP Project AA,"Performance Related Testing and Measuring of Asphalt-Aggregate Interactions and Mixtures," to evaluate available information on the fatigue, permanent deformation, thermal cracking, aging, and water.

Included in this report are the following: 1) a state-of-knowledge review for fatigue response of asphalt aggregate mixes, 2) a description of a pilot test program and its results, 3) a description of an expanded test program using the equipment and methodology selected in the pilot test program, and 4) a description of a mix analysis and design system, which can be used to mitigate fatigue cracking.

data are presented on the fatigue behavior of asphalt concrete mixtures based on a review of the literature, as well as research, which illustrate the effects of a number of mixture variables on fatigue response and include an indication of the influence of: mixture stiffness, air void content, aggregate gradation, aggregate type, asphalt content, and asphalt by: Literature review shows that there is less consistency among researchers about the effects of RAP on fatigue performance of asphalt mixtures.

Therefore, one of the main objectives of current study is to clarify the influence of various percentage of RAP on fatigue performance of asphalt mixtures. The development process included a number of phases which are described in the report Included in this report are the following 1) a state of knowledge review for fatigue response of asphalt aggregate mixes 2) a description of a pilot test program and its results 3) a description of an expanded test program using the equipment and methodology.

The asphalt mixtures' resistance to fatigue is a crucial parameter of the ma terial which affects the longevity of the whole p avement structure.

The effect is evident from the pavement design used. As a conclusion from the rutting and fatigue tests of asphalt binder and mixtures, using AC powder as binder additive improves the rutting performance and fatigue life at low strain levels.

Moreover, replacing up to 50% of AC powder by filler material leads to enhancement in rutting performance and has a slight and negligible negative impact on fatigue life of asphalt mixtures.

Testing for Fatigue Cracking in the Asphalt Mixture Performance Tester. This Technical Brief provides an overview of a fatigue characterization test method that can be conducted using an Asphalt Mixture Performance Tester (AMPT) device. This includes a description of the test as well as an introduction to how the test has evolved, what.

concrete pavements on major state highways. This report describes the results of a laboratory study of the fatigue response of a typical California asphalt concrete mix to define the effects of degree of compaction (as measured by air-void content), asphalt content.

The fatigue results of the sulphur modified asphalt mixtures have been compared with a standard dense bitumen macadam (DBM) control mixture made using the same gradation and the same 40/60 penetration grade base binder.

The fatigue comparisons were performed using the traditional strain criterion as well as a stress criterion. This report describes the results of a laboratory study of the fatigue response of a typical California asphalt concrete mix to define the effects of degree of compaction (as measured by air-void content), asphalt content, and aging on this performance parameter.

The present work utilizes strain-controlled bending beam fatigue test on asphalt mixtures to demonstrate the efficacy of this method.

Distortions in the hysteresis loop or waveform are tracked to pinpoint the appearance of initial micro-cracks and final point of complete failure due to fatigue damage.

For pavement design purpose, the fatigue performance of asphaltic materials is generally evaluated at a fixed temperature.

However, previous results indicate a significant influence of the. A literature review indicates the variation of air void content, aggregate gradation, and asphalt content to be expected on typical construction projects. This information together with the fatigue data presented previously allows the engineer to assess the relative importance of these mixture variables on predicting the performance of pavements.

Load-associated cracking is still one of the most critical distresses affecting the performance of hot-mix asphalt (HMA) mixtures used as paving material. This distress results as a consequence of repeated vehicle load application on HMA mixtures, without reaching the ultimate strength, leading to material fracture by fatigue.

Evaluation of the stiffness and fracture characteristics in direct tension, taking cognizance of the LCPC experiences, also will be accomplished since the use of a direct tension test has the potential to reduce considerably the time required to define fatigue response of asphalt-aggregate mixtures as compared to repetitive load testing.

gradation is an effective factor for fatigue resistance of asphalt mixture even a lot more than the effects of asphalt content (Hafiang, ). Fatigue behavior of the bituminous mixtures can be characterized by Beam Fatigue Test (Figure 2) or Indirect Tensile Fatigue Test (ITFT) (Figure 3) in controlled stress and strain modes.().
