Effect of Cement on Emulsified Asphalt Mixtures
Journal of Materials Engineering and Performance, 2007Emulsified asphalt mixtures have environmental, economical, and logistical advantages over hot mixtures. However, they have attracted little attention as structural layers due to their inadequate performance and susceptibility to early life damage by rainfall.

A continuum damage model for asphalt cement and asphalt mastic fatigue
International Journal of Fatigue, 2016Abstract An analytical model is developed for the mechanical degradation of asphalt cement and mastic under repeated loading. The model is derived by applying the strain decomposition principle to consider linear viscoelastic, nonlinear viscoelastic, and damage mechanisms.

Rheological Behavior of Fresh Cement Asphalt Mortar
Sustainable Construction Materials 2012, 2012Cement asphalt mortar (CA mortar) is the key component in the structure of Shinkansen slab track and serves as the elastic shock-absorber. CA mortar is a composite material with cement and asphalt emulsion and acts as a cushion layer in the structure of slab track.

Viscosity of Asphalt Cements at Intermediate Pressures
Product R&D, 1974A suspended two-piston capillary system for measuring flow of asphalt cements at up to 700 atm is described. The method was used to report the variation in viscosity with pressure on 14 different asphalt cements at 10, 25, and 60 DEG C. The general applicability of the Doolittle exponential relation for the data was demonstrated, and a discussion of ...

Effect of asphalt-to-cement ratio on strength of cement asphalt mortar used in high-speed railway
Transport and Communications Science JournalThe ballastless track structure (slab track) structure is commonly used in high-speed railway construction today. For this type of railway structure, the cement asphalt mortar polymer (CAM) layer plays an important role in damping, creating smoothness, reducing noise and ensuring simultaneous operation of the structure.
