Chuck Valentine , president of Valentine Surfacing Co. , Vancouver , Wash. , and past president of the Asphalt Recycling and Reclaiming Association , says that the four main types of recycling and reclaiming - cold in place recycling , hot in place recycling , full depth reclamation and cold planing - are all established methods that continue to improve.I think they ( those involved with recycling and reclaiming ) will continue to refine those processes and they will become more productive and effective in those processes , says Valentine.Several issues and challenges impact the recycling and reclaiming segment of the asphalt industry , and contribute to its growth.Gaining credibility within the industry has been a huge challenge for many involved in recycling and reclaiming.Learning how to effectively use reclaimed asphalt pavement has also been a learning experience.New equipment and innovative techniques make the process of recycling and reclaiming more productive , efficient and profitable.The question of funding , as always , plays a key role in the industry , especially with the introduction of the Transportation Equity Act for the 21st Century.But , even with the prospect of more recycling and reclaiming projects , industry experts wonder if those involved with the processes are adequately trained.

According to Valentine , due to TEA-21 , the different state DOTs are going to have larger budgets than what they've had in the past.There will be more dollars overall that they will have to spend , he says.And , of those total dollars , there will be an emphasis on system preservation , which lends itself to the recycling and reclaiming techniques.There will be more money , which translates into more projects that involve recycling and reclaiming..
Research fine tunes the art of recycling and reclaiming.Fine tuning the art of recycling and reclaiming is a neverending cycle.In order for the art to be respected , it must be validated.

So , they are trying to come up with a standardization of those processes , says Valentine.This is encouraging because it will lend more credibility to the process if there is an established procedure for it.I think more people will do the process if they feel comfortable with what they're doing and specifying..The North Central Superpave Center , located at Purdue University , Lafayette , Ind. , leads one such effort.A study is being conducted there to create specs for RAP use in Superpave mixes.
