Adsorption behaviour between cement and asphalt emulsion in cement–asphalt mortar

Advances in Cement Research, 2009
The workable time of cement–asphalt mortar (CA mortar) is controlled by the early age interaction between cement and asphalt emulsion, which could be indicated by the adsorption of asphalt droplets in the emulsion on cement grains. The adsorption behaviour leads to an increase in particle size in the cement and asphalt emulsion (CAE) system.

Thermal behavior of asphalt cements

Thermochimica Acta, 1998
Asphalt cements are highly complex mixtures of hydrocarbon molecules whose thermal behavior is of prime importance for petroleum and road industry. From DSC, the determination of several thermal properties of asphalts is given, e.g. glass-transition temperature and crystallized fraction content.

Nonlinear viscoelastic analysis of asphalt cement and asphalt mastics

International Journal of Pavement Engineering, 2014
The nonlinear viscoelastic (NLVE) behaviour of asphalt cement and asphalt mastic are studied using temperature and frequency sweep tests and repeated stress sweep cyclic load tests. These experiments show that the response functions of these materials are strain-level dependent.

Comparative study on mechanical performance of asphalt–cement mortar and emulsified asphalt–cement mortar

Road Materials and Pavement Design, 2016
The composite materials of asphalt–cement (AC) mortar were designed and produced by using different asphalt addition techniques. The objective of this research is to analyse comparatively the mechanical performance of AC mortar and emulsified asphalt–cement (EAC) mortar.

Effect of cement and emulsified asphalt contents on the performance of cement-emulsified asphalt mixture

Construction and Building Materials, 2019
Abstract The effects of cement and emulsified asphalt contents on the performance of cement-emulsified asphalt mixture were systematically evaluated, including the indirect tensile strength, compressive strength, modulus of resilience, tensile strength ratio, dynamic stability, maximum bending strain, and Cantabro loss.

Preliminary Study on Asphalt Emulsion Used in Cement Asphalt Mortar

Journal of Testing and Evaluation, 2009
Abstract Asphalt emulsion is an important component in the preparation of cement asphalt mortar. In the work reported here, different emulsifiers and basic asphalts were used to manufacture emulsions and their properties were investigated.

Strength Mechanism of Cement-Asphalt Mortar

Journal of Materials in Civil Engineering, 2011
The strength mechanisms of two kinds of cement-asphalt (CA) mortar, which vary principally in their strength and elastic modulus, were investigated by environmental scanning electron microscopy, calorimetry, and strength tests. The results showed that the asphalt emulsion delayed the early hydration of the cement and the asphalt membrane had a negative
