Nu-phalt™ Thermal Road Repair System
Nu-phalt™ offers a cutting-edge solution for road and pothole repairs with its patented thermal repair system. Designed to address the limitations of traditional methods, Nu-phalt™ delivers seamless, heat-sealed repairs using minimal new material, significantly reducing waste, noise, and disruption.
Overview
The Thermal Patcher Technology has created a revolution in road and pothole repair – a self-contained infrared system that is faster, more-cost effective, and more environmentally-friendly than traditional surfacing repair methods.
how it works - 6 Stages Process

Heating
The portable thermal heater is positioned over the defect area. An 8 minute pulsed heat cycle allows the fully controllable and efficient NIT heater to penetrate the wearing course to relinquish its strength, creating a workable material without carbonising or damaging it .
01

Scarification
To deliver a strong seamless joint, operators scarify an area 50mm in from the repair edge. This ensures integrity of the heated thermal joint between new and existingmaterial. No material is taken from the repair, everything is recycled in-situ, resulting in no waste or landfill.
02

Rejuvenation
High-grade enriched emulsion is added to the repair area. This is evenly mixed through the recycled material to deliver a consistent and even exposure. This recoats the recycled aggregate increasing bitumen content to near ‘new materials’.
03

New Material
BBA HAPAS approved material is supplied in 25kg bags for ease of use and is fed to and from the on board hot box’s. New material is heated to 100°C before being transferred to the repair area. Sufficient levels of material are added to create a level repair following compaction.
04

Checking Temperature
An infraredThermometer is used to check the temperature of the repair area, material temperature should be typically between 70-100°C to provide the best compaction conditions. This many vary depending on material used.
05

Compaction
Compaction equipment is specified in line with the repair area’s requirements. All edges are compacted to create a mechanical interlock with the surrounding surface.
