Case Study<\/p>\n\t\n

\n\t\t\tRoad Repair & Sealing Works at Norfolk Island\t<\/h2>\n\t

A rapid, low\u2011disruption road rejuvenation using cold\u2011applied technologies-PotHole Fix (PHF\u2122) and Pavement Rejuvenation Seal (PRS\/TL2000)-delivering strong sustainability, safety and lifecycle advantages.<\/p>\n\t\t\n\t\t

\n\t\t\tProject<\/strong> Overview\t<\/h2>\n\t

Taylors Road-an aged asphalt carriageway omitted from a prior overlay-showed oxidation, cracking and frequent potholes. Working with Norfolk Island Regional Council, we delivered patch repairs and a full\u2011width rejuvenation using PHF\u2122 and PRS\/TL2000. Local crews were up\u2011skilled to operate a simple spray\u2011truck configuration and finishing workflow.<\/p>\n

\n\t\t\tTrial Areas:\t<\/h3>\n\t

6,570 m\u00b2 planned; 5,942 m\u00b2 sealed (7.3 m wide).<\/p>\n

\n\t\t\tTimeline:\t<\/h3>\n\t

9-19 Jan 2023, aligned to shipping & weather windows.<\/p>\n

\n\t\t\tTraffic:\t<\/h3>\n\t

Sections reopened two hours post\u2011application.<\/p>\n

\n\t\t\tTech<\/strong> Stack\t<\/h2>\n

\n\t\t\tPHF\u2122 (PotHole Fix):\t<\/h3>\n\t

permanent patching in thin or deep lifts; hydrophobic and workable in wet or dry conditions.<\/p>\n

\n\t\t\tSpray\u2011truck:\t<\/h3>\n\t

simple configuration (airless sprayer, transfer pump, generator, drums) using locally available plant.<\/p>\n

\n\t\t\tPRS\/TL2000: \t<\/h3>\n\t

spray\u2011applied surface rejuvenation that seals against water\/chemicals, shields UV, and restores binder flexibility.<\/p>\n

\n\t\t\tWhy This Method Is More Sustainable<\/strong>\t<\/h2>\n\t\t\t\t\t\t
Cold manufacture & application<\/h5>\n\t\t\t

Cold manufacture & application avoids the high energy input and emissions of hot\u2011mix asphalt and emulsion\u2011based sprays.<\/p>\n\t\t\t\t\t\t

Rapid curing <\/h5>\n\t\t\t

Rapid curing (often within 2 hours) reduces traffic disruption, idling emissions and work\u2011zone exposure.<\/p>\n\t\t\t\t\t\t

Health, Safety & Environment friendly<\/h5>\n\t\t\t

Non\u2011emulsion, solvent\u2011free formulations backed by SDS; no diesel or detergent admixtures common to traditional “cold mixes”.<\/p>\n\t\t\t\t\t\t

Life\u2011extension<\/h5>\n\t\t\t

Life\u2011extension of existing pavements through rejuvenation and sealing defers high\u2011carbon reconstructions and overlays.<\/p>\n\t\t\t\t\t\t

Local capability<\/h5>\n\t\t\t

Local capability enables ongoing maintenance with minimal import logistics and lower embodied transport emissions.<\/p>\n

\n\t\t\t\t\"kmg-logo-sm\"\n\t<\/figure>\n

\n\t\t\tLifecycle Advantage:<\/strong>\t<\/h2>\n\t

A cost\u2011benefit model comparing rejuvenation to asphalt overlay or traditional seals can show superior Net Present Value (NPV) and faster payback (e.g., 2-5 years), driven by lower inputs, rapid delivery, and deferred major works.<\/p>\n

\n\t\t\tScope<\/strong> & Method\t<\/h2>\n

\n\t\t\tPre\u2011work assessments<\/strong>\t<\/h2>\n\t

Identified five patch areas; confirmed strong limestone\u2011like base; milling depths ranged 10-100 mm.<\/p>\n

\n\t\t\tPatch & pothole repairs<\/strong>\t<\/h2>\n\t

PHF\u2122 used for patches 1-5 and Works Depot corner reprofiling (single\u2011lift up to ~600 mm); hydrophobic behavior expelled water through capillaries after placement.<\/p>\n

\n\t\t\tSpray configuration<\/strong>\t<\/h2>\n\t

Airless sprayer, gear pump, generator, mixing drums on a council tray\u2011truck; 4-5 person crew.<\/p>\n

\n\t\t\tRejuvenation seal<\/strong>\t<\/h2>\n\t

PRS\/TL2000 applied at ~0.84 kg\/m\u00b2 average to 5,942 m\u00b2; staged to manage traffic; 2\u2011hour cure before reopening.<\/p>\n

\n\t\t\t\t\"kmg-logo-sm\"\n\t<\/figure>\n

\n\t\t\tResult:\t<\/h2>\n\t

Smooth, sealed carriageway with restored binder flexibility and protection from UV and water ingress.<\/p>\n

\n\t\t\tOperational Benefits<\/strong>\t<\/h2>\n

\n\t\t\tRapid Reopening: \t<\/h3>\n\t

Immediate opening to traffic after PHF\u2122 compaction; PRS stages reopen after ~2 hours.<\/p>\n

\n\t\t\tEfficient Deployment:\t<\/h3>\n\t

Minimal plant required; high productivity with small trained crews.<\/p>\n

\n\t\t\tSurface Correction:\t<\/h3>\n\t

Thin\u2011lift capability for surface correction and overlays.<\/p>\n

\n\t\t\tCommunity & Safety<\/strong>\t<\/h2>\n

\n\t\t\tHazard Reduction:\t<\/h3>\n\t

One\u2011step permanent fixes reduce hazard windows.<\/p>\n

\n\t\t\tWorker Safety:\t<\/h3>\n\t

Cleaner chemistry and cold application improve worker conditions.<\/p>\n

\n\t\t\tCommunity Impact:\t<\/h3>\n\t

Faster delivery reduces noise, delays and detours.<\/p>\n

\n\t\t\tFrequently Asked Questions<\/strong>\t<\/h2>\n\t\t\t\t\t\t
How does PRS\/TL2000 extend pavement life?<\/h5>\n\t\t\t

It penetrates the oxidised asphalt to restore binder flexibility while leaving a durable surface film that seals against water and shields UV-two primary drivers of asphalt ageing.<\/p>\n\t\t\t\t\t\t

Can PHF\u2122 be placed in wet conditions?<\/h5>\n\t\t\t

Yes. It is hydrophobic and workable in wet or dry conditions, enabling rapid permanent repairs even with standing water present.<\/p>\n\t\t\t\t\t\t

What crew and equipment are required?<\/h5>\n\t\t\t

A 4-5 person crew with a council tray\u2011truck configured with an airless sprayer, transfer pump, generator and mixing drums plus standard traffic management and light rollers.<\/p>\n
