The addition of rubber polymer to liquid or heated asphalt generally improves field performance because it imparts flexibility to the asphalt, thus improves Crack Sealing Machine working efficiency. Crack Sealing Machine need to choose proper crack material. the degree of flexibility basically depends on the type and nature of the asphalt, the percentage of vulcanized rubber used, and how the rubber is incorporated into the asphalt. Other polymers are often incorporated into asphalt, either exclusively or along with rubber, to increase resilience.
The following is the generally increasing trend in performance characteristics of polymer modified asphalts:
Poly-Modified Liquid Asphalt G Asphalt Rubber G
Rubberized Asphalt G Low-Modulus Rubberized Asphalt
Chemically cured thermosetting materials are one or two component materials that cure by chemical reaction from a liquid state to a solid state. This type of material has been used in common pavements, which can be better used by Crack Sealing Machine only in recent years. Self-leveling silicone is a one-component, cold-applied sealant that requires no tooling.
