FORMULATIONS

Western Asphalt Products understands that road construction and maintenance issues are as unique as their respective solutions. In light of this, Western Asphalt Products has immense capability in formulating tailored solutions unique to customer’s issues. Western Asphalt’s Laboratory is equipped with a lab-mill capable of direct replication of Western Asphalt’s entire plant, including correlation of particle size-distribution to the micron (literally)! Whatever properties you are after, allow our laboratory to formulate a tailored solution for your company. Western Asphalt Products is behind your goals.

Micro-Surfacing & Slurry Formulation

As Micro-Surfacing and Slurry Seal projects rely heavily on an intimate aggregate-emulsion compatibility, Western Asphalt Products formulates aggregate-specific mix-designs through the use of standards as outlined by the International Slurry Surfacing Association (ISSA). Western Asphalt Products is capable of performing the following mix design procedures:

  • ISSA Technical Bulletin 100 – Wet Track Abrasion of Slurry Surfaces
  • ISSA Technical Bulletin 106 – Measurement of Slurry Seal Consistency
  • ISSA Technical Bulletin 109 – Measurement of Excess Asphalt in Bituminous Mixtures by Use of a Loaded Wheel Tester and Sand Adhesion
  • ISSA Technical Bulletin 113 – Trial Mix Procedure for Slurry Design
  • ISSA Technical Bulletin 114 – Wet Stripping Test for Cured Slurry Seal Mix
  • ISSA Technical Bulletin 139 – Test Method to Classify Emulsified Asphalt/Aggregate Mixture Systems by Modified Cohesion Tester Measurement of Set and Cure Characteristics
