A 'dry mix" asphalt additive that provides solutions for the most punishing conditions with superior protection capabilities:
Waterproofing/Wearing Course Toll Booths/Docks/Weigh Station Airport "FR" Solutions Access Ramps/Reflective Cracking Solutions Motor Speedways
Rosphalt Asphalt Additive Provides:
Superior Waterproof Wearing Surface Fast Track Construction Solver Longer Life/Cost Effective Solutions
Royston offers three (3) versions of Rosphalt: 1) Rosphalt 50 as a waterproofing/wearing course system in a 1-step application. 2) Rosphalt Rx as a high performance wearing course resisting reflective cracking, rutting and shoving. 3) Rosphalt FR is a new high performance design mix that is Fuel Resistant.
	Rosphalt is a DESIGNED DRY MIX, cost competitive Asphalt additive used with a variety of mix designs, that has a proven track record of superior performance over other HMA, PMA, and concretes, combined with more flexibility and stability "THE BEST OF BOTH WORLDS" High Performance has never come easier
Faster Installation/lowering traffic control cost Superior waterproofing Better skid resistance Better ride ability/Less noise Better resistance to Thermal/Fatigue cracking Resist rutting/shoving Longer pavement life Little to no maintenance Long term cost savings – Most cost effective
Royston offers three (3) versions:
Rosphalt 50 for a Superior Waterproofing and Wearing Course in a 1-step application. Rosphalt Rx for a Superior High Performance Wearing Course that resists Reflective Cracking, Rutting and Shoving, helping to create a Perpetual Pavement.
Independent Testing supported by the latest standards from ASTM & AASHTO:
Superior Impermeability Better Skid resistance Superior resistance to rutting/shoving at varying grade levels Over twenty years of performance Uses standard paving equipment
Bridge Deck OverLays (R50)
	Used on any composite bridge design Replacement for any waterproofing system, such as Sheet, Torch, or Spray applied systems Replacement for Epoxy, Latex Modified, Silica Fume or High Performance concrete overlay Better cost savings in project, traffic control, future maintenance, and overall life Fast application, getting the project open to traffic, with much less inconvenience
Enhanced Roadways and Tunnel Solutions (R50 or Rx)
	Used over almost any solid substrate base, creating Long Life Perpetual Pavements Replacement for any waterproofing membranes Better cost savings in project and traffic control Open to traffic as soon as installation is complete, with less inconvenience to the traveling public
Airport Design Mixes-Aprons/Taxiways/ Runways (RFR)
	Used over any solid substrate base Used with P401 designs modified Better cost savings on long term life and maintenance Stronger and more durable No waiting or cure times during installations Aircraft allowed access almost immediately.
Motor Speedways and Garage Waterproofing (R50/Rx)
	Used over MOST solid substrate bases Replacement for concrete, PG78-22/TLA or crumbed rubber Better cost savings on long term life and less maintenance Stronger and more durable than conventional systems No waiting or cure times after installations Excellent skid numbers for better traction Easily applied using standard paving equipment
