Apple, that process looks to be more thorough and involved than what is going on here.
I don’t think it is necessarily cheaper to do this process.... but there are advantages, especially on mountainous roads or heavy traffic roads. It’s faster to do, so it less impact on traffic. They don’t have to break up the old road and haul it away in dump-truck loads which takes time, requires a lot of extra working space and holds up traffic more while they are working.
They told me that the success of the end result depends greatly on the project chemist getting the mixture right. As their machine breaks and grinds up the old surface, the on-site chemist tests the ground up stuff and determines the proper mixture for the new surface.... it is mixed right there, added to the machine and the procedure continues.
Like I mentioned before.... this company is having great success here in Georgia. Maybe the Minnesota company needs to take a lesson from this GA company??
