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 ... -
Comprehensive evaluation of long-term aging of asphalt mixtures in hot climatic condition
( Taylor & Francis , 2018 , Article)Aging is an inevitable phenomenon in hot mix asphalt production and during in-service period of flexible pavement operation. This paper presents an experimental evaluation of long-term aging of asphalt mixtures in Qatar. ... -
Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases
( OMICS International , 2014 , Article)More than 15 million tons of aggregates are imported each year to Qatar from neighbouring countries. Large quantities of waste materials (around 20 million tons/year) from excavation waste, demolition rubble and reclaimed ... -
Nano-scale moisture damage evaluation of carbon nanotube-modified asphalt
( Elsevier , 2018 , Article)© 2018 Elsevier Ltd In addition to polymer modification, the use of nanomaterials to improve different asphalt properties has recently been found to be beneficial. However, the potential of nanomaterials in pavement ... -
