Abstract This study aims to evaluate the performance of magnesium phosphate cement and emulsified asphalt combination (MPC–EA) on the scale of paste, mortar and concrete, respectively. Experimental results indicated that the emulsified asphalt was more efficient in extending the setting time (from 10 to 90 min) than traditional retarders (borax and ...

Network morphology of straight and polymer modified asphalt cements
Microscopy Research and Technique, 1997Asphalt cements are often regarded as a colloidal system containing several hydrocarbon constituents: asphaltenes, resins, and oils. The high molecular weight asphaltene particles are considered to be covered in a sheath of resins and dispersed in the lower molecular weight oily medium [Whiteoak (1990) The Shell Bitumen Handbook (Shell Bitumen UK ...

Assessing Rheological Behavior of Modified Paving Asphalt Cement
American Journal of Civil and Structural Engineering, 2014The Asphalt cement is produced as by-product from oil industry in Iraq; the asphalt must practice further processing to control the percentage of its different ingredients so that it will be suitable for paving process. If such processing is not conducted, then another alternative of modifying the asphalt cement properties with additives could be ...

The microstructure evolution of cement paste modified by cationic asphalt emulsion
Advances in Cement Research, 2021Cationic asphalt emulsion (CAE) is a type of organic latex that could be used to modify cement hydration products in order to improve the performance of cement paste. In this study, different methodologies were used to investigate the influence of CAE on the process of cement hydration.

Mechanism of Interaction of Asphalt Cement with Crumb Rubber Modifier
Transportation Research Record: Journal of the Transportation Research Board, 1999The nature of the interaction process between asphalt cement and crumb rubber modifier (CRM) has not been fully understood. Two main types of mechanisms that affect the produced binder properties are reported: particle swelling and degradation (devulcanization and depolymerization).

Fatigue Property Analysis of Modified Asphalt Emulsion-Cement Cold Recycling Mixtures
Advanced Materials Research, 2012The fatigue property of rectangular section beam for semi-flexible cold recycling mixtures has been analyzed basing on damage-fracture mechanics principles. Fatigue models of rectangular section beam have been put forward respectively, which includes both macroscopic cracks appearance and propagation process.

Asphalt emulsion is a common material used for pavement base course stabilization, and cement is usually added as an active filler to improve the stability of asphalt emulsion mixtures further. However, using cement in these mixes has several drawbacks, including high material costs and environmental issues.
