1. Compared to ordinary slurry seal, microsurfacing uses wear-resistant aggregates, resulting in better wear resistance and skid resistance.
2. Microsurfacing has better rut repair capabilities.
3. They can prevent surface water infiltration, thus better protecting the pavement structure.

4. Provided the subgrade and pavement are stable, well-done microsurfacing can have a service life of over 5 years.
5. Both microsurfacing and slurry seal are mechanized, resulting in fast construction speeds and high efficiency.
6. Slurry seal has a relatively lower cost but limited application. Microsurfacing, while more expensive, can be used for the maintenance of various asphalt pavements, including highways.
7. Both microsurfacing and quick-opening slurry seal allow for rapid traffic reopening, with traffic possible within 1-2 hours after construction, minimizing the impact on traffic.
So, is microsurfacing always better than slurry seal? Of course, it's not always the case. During the application of the undercoat, people often choose the lower-cost, waterproof slurry seal over microsurfacing. Nor can one be definitively said to be better than the other. They each have their own function, and the best choice is the one used appropriately.
