Application of plateau value to predict fatigue life [PDF]
, 2009 Fatigue resistance of asphalt mixtures represents an important parameter for pavement design. This fatigue resistance is calculated through laboratory tests which require some time depending on the strain level applied to the specimen.

Deformation characteristics of asphalt mixtures
E3S Web of ConferencesAsphalt pavement is among the most widespread road surfaces. For their design, assessment, and service life, it is necessary to evaluate the deformation characteristics of asphalt mixtures, which include the complex modulus of rigidity. Two-point (2PB-TR) and four-point (4PB-PR) flexural tests are used to determine these.

Sustainability of Asphalt Mixtures Containing 50% RAP and Recycling Agents
RecyclingThe substitution of virgin asphalt binder with reclaimed asphalt pavement (RAP) has environmental and economic merits, however, cracking susceptibility arises due to the aged asphalt binder within RAP.

Application of Cantabrian and Binder Drainage Tests in Designing of Porous Asphalt Binder Content [PDF]
, 2004 Traditional mix design methods which normally incorporate the Marshall test are not appropriate to design porous asphalt because of the insensitivity of the Marshall stability values to variations in binder content.

Crack Initiation Assessment of Wearing Course Asphalt Mixtures Using Aggregate Gradation Characteristic [PDF]
, 2007 At normal service temperatures, wearing course asphalt mixtures may have ductile cracking. Aggregate gradation characteristic is important to avoid the premature cracking. The present study discusses a relationship between the characteristic of aggregate

Evaluation of the stiffness modulus of bituminous mixtures using laboratory tests (NAT) validate by field back-analysis [PDF]
, 2005 This paper concerns the evaluation of the stiffness modulus of bituminous mixtures by using the Nottingham Asphalt Tester (NAT). On the basis of indirect tensile laboratory test results, a practical model for stiffness modulus prediction in pavement ...

Reinforcement of Asphalt Concrete Mixture Using Polypropylene Fibers
Syrian Journal for Science and InnovationThe performance of asphalt roads is affected by many factors such as temperature, water, loads and materials characteristics. These factors cause thermal cracking, permanent deformation (rutting) and fatigue distresses on asphalt concrete layers.
