I. Properties
Slurry Seal: Slurry seal is a mixture of cement, lime, stone powder, gravel, asphalt, etc., which forms a thin slurry upon the addition of water. Its main characteristics are ease of use, simple construction, fast curing, good durability, and strong adhesion to existing pavements. Therefore, slurry seal is commonly used for the repair and waterproofing of old pavements.
Emulsified Asphalt: Emulsified asphalt is a mixture of asphalt, emulsifier, water, etc., which forms an emulsion after mechanical mixing. Its main characteristics are good adhesion, strong water resistance, easy construction, and good environmental friendliness. Therefore, it is commonly used in highway maintenance for new pavement paving, road reconstruction, and waterproofing.

II. Applications
Slurry Seal: Slurry seal is mainly used for the repair and waterproofing of old pavements. Due to its simple construction, fast curing, and good durability, it is also frequently used for the reinforcement and reconstruction of old pavements. Emulsified Asphalt
Emulsified asphalt is mainly used for paving new roads, road reconstruction, and waterproofing. Due to its good adhesion, strong water resistance, convenient construction, and environmental friendliness, it is widely used in highway construction.
III. Cost
Slurry Seal
Slurry seal has a relatively low cost because its main materials are cement, lime, stone powder, gravel, and asphalt, which are relatively common and have stable prices.
Emulsified Asphalt
Emulsified asphalt has a relatively high cost because its main materials are asphalt, emulsifiers, and water, which are more expensive and susceptible to market fluctuations.
【Conclusion】 Through the above comparison, we can conclude that slurry seal and emulsified asphalt differ in properties, uses, and costs. Therefore, when choosing materials, it is necessary to select according to specific circumstances and needs to achieve the best maintenance effect.
