Chip Seal with Geotextile Fabric

Double shot chip seal was placed on geotextile fabric in Cecil County, Maryland as a pavement preservation method to extend the roadway's useful life.  

Basil Avenue (18-20' width) was an existing concrete roadway with approximately 2" asphalt overlay.  The surface exhibited oxidation and some cracking.  Cecil County performed some sealing of the distressed/cracked asphalt with an AMZ machine, but the surface was not crack sealed.  Most of the reflective cracking due to transverse joints were not sealed.  Some asphalt patching (~2" thick) of the existing surface and some thin lift repairs (~1" thick) preceded the chip seal and fabric treatment.  The video shows the June 27, 2012 application of PG-64 binder and Mirafi MPV 500 polypropylene non-woven fabric followed by two layers ("shots") of chip seal, using 0.4 gal/SY CRS-2 emulsion (second layer used 0.37 gal/SY) and #8 stone at 17 #/SY (both layers).
