In June 2012, Cecil County
In June 2012, Cecil County (Maryland) Roads Division treated Basil Avenue with some patching, followed by geotextile and a double shot of chip seal as a pavement preservation method to extend the roadway's useful life - Chip Seal with Geotextile Fabric.
Nine years later, the surface exhibits only minor cracks, with no apparent reflective cracking to date. Optimal performance expectations for chip seal would typically be 7-10 years (https://roadresource.org/), but it would appear that the treatment to Basil Avenue will enjoy a much more extended service life.
Basil Avenue (18-20' width) was an existing concrete roadway with approximately 2" asphalt overlay. The surface exhibited oxidation and some cracking in 2012. 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 (Chip Seal with Geotextile Fabric) 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).
