Regular Council Meeting <br />9-24-01 <br />Page 14 <br />Mayor Rinker: If I may, my question is because there is a big chunk of change difference between <br />the 2 but if I understand correctly that the more expensive spread, if we are going to do this, it <br />sounds like it's going to be quality. Just explain that if you would, again. Describe it. <br />Mr. Cappello: Traditionally, we use the geotextile fabric. It's actually like a fabric material. You've <br />seen it--remember on Worton Park--it actually had little cover. The other item is a reinforcing grid. <br />It is more of a plastic, actually like a netting but heavy duty strips. <br />Mayor Rinker: What mechanically do they do? What do they accomplish? <br />Mr. Cappello: Basically, what they do is they bridge over the cracks and help lessen the effect when <br />the pavement shifts as far as reflective cracking through the asphalt. You will still get some but my <br />understanding is according to the salesman that the geogrid is a higher--reaches its tinsel strength <br />quicker--which is stronger than the fabric. The fabric would have to elongate a lot longer--that is <br />why the cost is more. <br />Mayor Rinker: So it bonds better. <br />Mr. Cappello: It bonds better, it is supposedly a better reflective reducer. <br />Mayor Rinker: And you would still do the cracksealing? <br />Mr. Cappello: We would still do patching underneath the routing of it and then this would go over <br />the top of the cracks and then they would pave over the top of that. <br />Council President Marquardt: So we are looking at the $204,000? <br />Mr. Cappello: If you go with the geograde instead of the geotextile fabric, yes. <br />Mr. Brett: I think what we'd like to do is get references, see what communities have done it. <br />Mr. Metzung: Yes, having talked to other people in the field about the--and I don't know anybody <br />that has used this particular material so this may be different, but people that have used just a single <br />piece to go over top of cracked areas and one of the things they found was that they ended up with <br />two cracks--as opposed to the one in the middle, they ended up with the crack where the patch work <br />actually was--so they ended up with 2 cracks instead of one. So, that would be something I would <br />like to know--I'd like to know that before... <br />Mayor Rinker: Well this will run the length and breadth... <br />Mr. Metzung: No, the fabric... <br />Mr. Cappello: This one was--the square yardage actually was the entire pavement. <br />Mr. Metzung: Oh, my mistake. I thought it was just a patch material.
