Cold Mix Asphalt Additives
With our rapidly aging road infrastructure, better road maintenance solutions are needed. Pavement patching is one of the most widespread and costly maintenance activities undertaken by highway agencies at all levels. Most patching practices are conducted in less than ideal conditions. Many potholes are formed due to the presence of water, and are often cold and wet when repaired. If they are dry, they contain high amounts of dust and loose stones. These are certainly less than ideal conditions in which to perform pavement maintenance, thus necessitating the need for high-performance patching solutions.
Many potholes are repaired using cutback asphalt or emulsion-based cold patch stockpile mixes during the winter months when either hot mix is not available or the repairs are too small to warrant the use of hot mix. Potholes are often repaired reactively rather than proactively. As a result, repairs must be done quickly and are often performed without the traffic control normally seen in larger construction projects. Maintenance crews must be able to apply the pothole patch quickly and move on to the next repair. This again highlights the need for high-performance patching solutions.
As a contractor who provides the patching mix for pothole repairs, it is of the utmost importance that the product you offer perform in these less than ideal conditions. Your patching mix must provide uniform binder coverage over the aggregate and must not be susceptible to stripping in the stockpile or after the patching mix is used in the repair. The mix must remain workable, be easy to transfer to the pothole and easy to compact.
Road Science manufactures the following performance-improving asphalt additives for exceptional cold mix quality and performance, enabling you to differentiate yourself from the competition.
