Asphalt Rubber Chip Seal and Polymer Modified

Improving chip seal performance | Asphalt magazine

Chip seal basics. Different types of binders can be used in a chip seal. The binder may be cold or hot applied. Cold applied binders include modified and unmodified medium and rapid setting emulsions. Hot applied binders can be polymer-modified asphalt cements, asphalt rubber and polymer/crumb rubber blends, as well as unmodified asphalt cements.

CHAPTER 7 CHIP SEALS - csuchiedu

• Polymer-Modified Emulsion (PME) chip seals are used to correct raveling and pavement oxidation. • Rubberized chip seals cure quickly, restore skid resistance on worn surfaces and resist reflection cracking. • Binders such as asphalt rubber and polymer modified (PG) asphalts may be used to address specific distress modes.

Chip Seal Quality Construction - nevadadot

chip seals, pavement surface temperature must be at least 80°F and air temperature must be between 65-110°F. For polymer-modified emulsion chip seals, surface temperature must be at least 80°F and air temperature must be between 60-105°F. For asphalt rubber binder chip seals, surface temperature must be at least 55°F and

TRMAC™ - Tire Rubber Modified Asphalt Cement

The TRMAC™ process was developed to produce higher-quality products that last longer and provide superior performance. The TRMAC™ is then blended into various finished tire rubber products, which are used for pavement maintenance (high performance chip seals and surface sealers) and construction (high performance hot mix binders).
