Applications

• This mix design is optimized for four specific site conditions and traffic levels:

• Municipal Roads: For urban link roads and community collector streets.

• Light-Duty Pavements: For residential driveways, resort paths, and access roads.

• Commercial & Industrial Parking Lots: Formulated to resist heavy static tire scrubbing.

• Logistics Yards & Hardening Projects: Cost-effective solutions for sub-bases or wearing courses.

• Standard mix designs for limestone and basalt aggregates do not apply to Tonga's coral aggregates. Due to the highly porous nature of local coral and the lack of quarries capable of meeting standard grading requirements, we implemented specialized secondary screening and custom grading. Through extensive laboratory testing, we successfully developed a tailored mix design perfectly optimized for Tonga’s unique local aggregates.
