A hot rubber crack fill trailer is a piece of equipment that is used to heat and apply hot rubberized crack sealant to asphalt pavement cracks. The temperature range for using a hot rubber crack fill trailer effectively and safely depends on the type of crack sealant and the ambient temperature.
According to one source, the recommended temperature range for hot-pour crack sealant is between 40degree F and 400degree F. The cracks should be dry and heated to at least 40degree F to 50degree F using a torch or a hot air lance before applying the sealant. The kettle temperature can be up to 400degree F, which is the maximum heating capacity of the product, without ruining its bonding capability.
Another source suggests that the ideal temperature range for hot-pour crack sealant is between 275degree F and 350degree F. The cracks should be clean and dry before applying the sealant. The kettle temperature should be monitored and adjusted to maintain the proper application temperature.
A third source states that the optimal temperature range for hot-pour crack sealant is between 300degree F and 375degree F. The cracks should be free of moisture, dirt and debris before applying the sealant. The kettle temperature should be controlled to prevent overheating or underheating the sealant.
As a general rule, it is advisable to follow the manufacture's instructions and specifications for the type of crack sealant you are using, as different products may have different temperature requirements and characteristics. It is also important to wear proper protective equipment and follow safety precautions when using a hot rubber crack fill trailer, as the sealant can cause burns, fumes or fire hazards.
