Question:

What is a binder additive for asphalt and how do they apply them in the driveway?

A pavers advised me that when you apply this binder additive to your new asphalt for your driveway there is no need to seal it for 5 years.Is this true?

Answer:

There lying to you trying to get you to buy something you don,t need. asphalt is the binder, [mixed with gravel] and it has to be resealed in 5 yrs
Most asphalt additives are added at the plant where the paving materials are mixed. Otherwise you are dealing with a surface applied sealer. There are numerous additives for asphalt and each has a different issue they are improving. The specific additive they have suggested will have literature available that will cover the dosage, application, condition requirements, issues it proposes to resolve and if it increases the time before it needs to be resealed the literature will provide their claims. The paving contractor should provide the product literature for your review and comments. It is entirely possible an additive is available and probably there are many on the market. Review the product literature and make a decision based on the added cost and the value received. Sometimes surface sealers are applied as much for their appearance as their protection of the asphalt from oils etc. Once you start the sealer applications you will have to continue them periodically due to the surface wearing in the traveled portion of the drive.
