For rougher pavements, sand loading of 4 to 4.5 lbs. per gallon of undiluted sealer may be necessary to accomplish proper texturing and filling of fine cracks. Sand should Be clean, water-washed, pure silica type, with irregular particle shape, free of contaminants, metals, clay, trash and organic matter.
Sealcoating and crack filling is a fraction of the cost of repairing or replacing asphalt pavement. The key to effective crack filling and sealing is to repair and fill the cracks while they are small, as crack filling inhibits crack growth and keeps new cracks from forming.
Typically, glass columns are the first choice for self- and re-packing. There are two ways to re-fill a glass column, dry and slurry packing. Dry packing is fast and easy. The approach relies on compressed gas. With dry filling, the packing density is not as dense, so this method is better suited to medium to big sized silica particles 25-200 m.
Feb 05, 2021 The cement-silica slurry produced in PWRA in the first stage of mixing process allowed the slurry to penetrate through the old-mortar and filled the pore structures of the RCA.

Slurry seal and micro surfacing is ideal for pavements suffering from flushing, polished aggregate, raveling, oxidation and light to moderate cracking, said Dr. Andrew Braham of the University of Arkansas. Micro surfacing can also fill minor rutting and prevent cracks from growing wider, due to its use of polymer-modified emulsion.
