ABSTRACT Asphalt emulsion produced from local asphalt 60/70 (Suez Co.) was modified with different types of polymers such as epoxy resin, latex styrene butadiene styrene (SBS), poly vinyl acetate (PVA), and with a mixture of two or more types of above mentioned polymers to produce a modified asphalt emulsion with high performance. This paper describes the method and technique for preparing asphalt emulsion as well as the tests, and evaluates several aspects concerning the prepared emulsion such as performance of evaporation residues, fuel and acid resistance, rheological properties, and durability. The results obtained revealed that all the modified asphalt emulsions gave better performance as compared with unmodified emulsion. Asphalt emulsion modified with a mixture of epoxy resin, latex SBR, and PVA showed the best road performance in terms of fuel and acid resistance. It was observed that the weight loss for unmodified binder, residue after evaporation of water, after immersion in kerosene for 120 min is 90% of its initial weight, while the binder improved with a mixture of SBS latex, epoxy resin, and PVA showed a weight loss of −16% and 9% of its initial weight. Also, the admixture gives high acid resistance (weight loss ∼ 9%) after immersing in 5% HCl. The dynamic viscosity test showed that asphalt emulsion modified with a mixture of SBS latex, epoxy resin, and PVA has the highest viscosity value which is a promising indication about the validity of its use for pavement in different applications.

The use of reactive polymers as modifiers for asphalt appears promising. Asphalt penetration grade 60/70 cannot be used in coating applications for its long drying time at ordinary temperature and for its brittleness at very cold temperature. This material is very cheap as compared to blown asphalt that usually used in industrial applications. This study aims to use reactive polymers in modification of soft asphalt to produce very specific asphaltic material for use in infrastructure applications especially coating instead of highly expensive materials. The new asphaltic material is low cost and has high quality performance at low temperature. To achieve the aim of study, RRNP was used as additive to modify asphalt in percentages of 3, 5, 7 and 10% w/w. The prepared RRNP was then tested for their particles size using DLS and TEM, SEM, 1HNMR. RRNP was used to modify the thermo mechanical properties of asphalt via forming chemical bond, and the changing in mechanical and thermal properties of the mixes as well as the storage stability were studied. Also, the morphology (SEM), thermal characterization (TGA), Dynamic mechanical analysis (DMA), rheological tests, while, the prepared coatings were applied to carbon steel panel and tested for bending, Abarsion test and impact test were detected. Overall, the results show that the chosen modifiers are the best so far in the modification of soft asphalt to suit the industrial applications in different climate conditions.
