New formulations and improved laboratory procedures have been developed to satisfy design and construction requirements. Polymer modification has allowed the use of emulsions for techniques not previously considered, such as microsurfacing and chip seals on high traffic volume highways . The ability to use cold materials at remote sites. The ability to handle asphalt emulsions at lower temperatures, and the lower flammability of water based materials increases safety for workers. The ability to increase the service life of slightly distressed existing pavements.
Preventative maintenance is a more cost-effective use of highway dollars.
The ability to recycle . Asphalt emulsions are being used extensively in a variety of recycling systems. They are particularly suited to in-place recycling . Pavements constructed with asphalt emulsions will also be able to be recycled in the future.
