Implementation of mechanistic-empirical pavement analysis in the State of Qatar
(
Taylor & Francis
, 2014 , Article)
The State of Qatar is experiencing tremendous growth in infrastructure including road network and highways. The current methods used in design of asphalt pavements in the State of Qatar are empirical and might not be ...
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
(
Kluwer Academic Publishers
, 2016 , Article)
Warm-mix asphalt (WMA) additives are environmentally friendly and cost-effective products that lower the viscosity of bituminous binders to allow reduction of mixing and compaction temperatures in asphalt mix production. ...
Effect of ageing on asphalt binders in the State of Qatar: a case study
(
Taylor and Francis Ltd.
, 2017 , Article)
Ageing of asphalt binders has a significant impact on the rheological properties of asphalt binders and thus affects the performance of asphalt pavements. The rate of binder ageing is accelerated at high temperatures. This ...
Probabilistic analysis of fatigue life for asphalt mixtures using the viscoelastic continuum damage approach
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the most serious distress modes affecting the serviceability of asphalt pavement structures. The inherent variability of asphaltic materials exhibited in fatigue test results, especially for ...
Comparative evaluation of fatigue resistance of warm fine aggregate asphalt mixtures
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the crucial distresses in asphalt pavements that affect its service life and rehabilitation process. The resistance of asphalt mixtures to fatigue failure in the laboratory experiments is influenced ...
Aging evaluation of asphalt samples with Low Field Nuclear Magnetic Resonance
(
Elsevier Inc.
, 2017 , Article)
In this study, a recently developed methodology to assess aging of pavements by using Low Field Nuclear Magnetic Resonance (LF-NMR) was applied to asphalt mix samples at different aging states. The ultimate objective of ...
