Asphalt Content by Neutron Moderation
1969The neutron moderation method of asphalt content determination is investigated by evaluating the effects of temperature of the mix, mass specific gravity of the sample, asphalt source, penetration grade of the asphalt, aggregate composition and gradation, and asphalt content of the mixture on the response of an experimental asphalt content gauge ...

Performance Evaluation of Asphalt Mixtures with High Recycled Asphalt Pavement Content
Transportation Research Record: Journal of the Transportation Research Board, 2011This study extensively evaluated the resistance to moisture damage and thermal cracking of hot-mix asphalt (HMA) mixtures with high recycled asphalt pavement (RAP) content (up to 50%) from field sections on provincial Highway 8 between Gimli and Hnausa in Manitoba, Canada.

Mitigation Strategy Selection for Asphalt Mixtures with High Reclaimed Asphalt Pavement Content
Transportation Research Record: Journal of the Transportation Research Board, 2023Economics and sustainability goals have driven higher use of recycled asphalt materials (RAMs), such as reclaimed asphalt pavement (RAP) and recycled asphalt shingles, in the pavement industry. Owing to the brittle nature of aged binders found in RAMs, a mitigation strategy is usually needed to ensure adequate cracking performance.

Estimation of elastic modulus of cement asphalt binder with high content of asphalt
Construction and Building Materials, 2017Abstract In this paper, the effects of asphalt-to-cement ratio (A/C) and water-to-cement ratio (W/C) on the elastic modulus E c of cement asphalt (CA) binder were studied through measuring the stress-strain curves and phase volume fractions of various CA binder specimens. The results illustrate that the CA binder with high asphalt content (A/C ⩾ 0.

Effect of Emulsified Asphalt Content on Mechanical Property of Cement and Emulsified Asphalt Mortar
Applied Mechanics and Materials, 2014Uniaxial compression and bending test of CA mortar, which have six different dosage of emulsified asphalt and the same dry material, is carried out with a electronic universal test machine. It turns out that: when the dosage of emulsified asphalt is lacked, the CA mortar cannot be uniform and stable slurry system; within the range of 300~680 mL ...
