Hot Mix Asphalt (HMA)

Hawaiian Rock Products (HRP) operates two state-of-the-art hot mix asphalt (HMA) batch plants located in Fadian with production capacities of 300 tons per hour (TPH) and 150 TPH, respectively. Both plants are fully computerized to ensure precise mix proportioning, consistent quality, and efficient production. Supported by a dedicated transportation fleet, HRP is capable of producing and delivering more than 2,000 tons of asphalt per shift, allowing us to meet the demands of projects ranging from small roadway repairs to large-scale highway and airfield construction.

HMA Sustainability

Sustainability is an important part of HRP’s asphalt operations. Our larger asphalt plant is capable of incorporating up to 25% Recycled Asphalt Pavement (RAP) through the use of reclaimed asphalt millings from previous projects. By utilizing recycled materials, we reduce the consumption of virgin aggregates and imported asphalt cement while helping preserve Guam’s natural resources.

HRP is also capable of producing Warm Mix Asphalt (WMA), which allows asphalt production and placement at lower temperatures than conventional hot mix asphalt. This process reduces fuel consumption, lowers emissions, improves working conditions, and extends paving opportunities. Additionally, our asphalt plants utilize recycled oil as a portion of the burner fuel required for aggregate drying, further supporting our commitment to environmental stewardship and sustainable construction practices.

Construction & Paving Operations

HRP maintains multiple construction crews capable of performing grading, milling, asphalt paving, roadway rehabilitation, and pavement maintenance operations. Our crews are supported by a modern fleet of paving and construction equipment, including milling machines, pavers, motor graders, rollers, water trucks, distributors, sweepers, loaders, backhoes, and support vehicles. Many of our grading, milling, and paving operations utilize advanced GPS-guided grade control technology to improve accuracy, efficiency, and consistency while meeting the demanding tolerances required by today’s infrastructure projects.

Our extensive pavement maintenance capabilities include asphalt milling, cold planning, crack sealing, surface preparation, sweeping, tack coat application, and compaction operations. Specialized equipment such as distributors, milling machines, vacuum sweepers, and crack sealing units allow HRP to provide complete roadway rehabilitation services from surface preparation through final paving.

To ensure quality throughout the paving process, each paving crew is equipped with Pavement Quality Indicator (PQI) gauges that provide real-time density measurements during asphalt placement. This technology allows field personnel to monitor compaction levels continuously and make adjustments as necessary to achieve specified pavement densities and maximize pavement performance and longevity.

Engineering & Quality Assurance

A dedicated team of project engineers works closely with owners, consultants, and contractors to coordinate scheduling, documentation, quality assurance, and project execution. Our engineering staff supports projects from planning through completion to ensure compliance with contract requirements, project specifications, and industry standards.

All project engineers have successfully completed Construction Quality Management for Contractors (CQM-C) training as well as comprehensive construction safety and hazard awareness programs. Their expertise, combined with our modern equipment fleet and quality-driven approach, allows Hawaiian Rock Products to consistently deliver high-quality paving and construction services throughout Guam and the Mariana Islands.

Commitment to Investment and Reliability

Hawaiian Rock Products continues to make significant investments in plant modernization, paving equipment, roadway maintenance equipment, and fleet expansion to improve reliability, increase production capacity, and enhance operational efficiency. Recent additions to our paving fleet have strengthened our ability to provide dependable service while minimizing downtime and maintaining project schedules.

These ongoing investments reflect HRP’s commitment to delivering safe, sustainable, and high-quality asphalt products and paving services. By combining advanced technology, experienced personnel, and modern equipment, Hawaiian Rock Products remains one of Guam’s leading providers of asphalt production, paving, and roadway construction services.
