UPM-HPM Hot Mix Pavement Modifier



HPM® Hot Mix Pavement Modifier

Unique Paving Materials Corporation, the manufacturer of UPM® Permanent Pavement Repair Material, the most cost effective cold mix in the industry, now offers HPM® Hot Mix Pavement Modifier. HPM is a high-performance adhesion promoter formulated to improve the performance and longevity of asphalt pavements.

The unretouched photo of the core samples above shows an actual mix design with and without HPM. It is apparent that the sample without HPM exhibits stripping of the asphalt cement from the aggregate. Stripping or loss of adhesion leads to premature pavement failures. HPM dramatically improves adhesion and increases the tensile strength ratio of the mix.

High Performance = Cost Effectiveness

HPM is specially formulated to increase the lifespan of asphalt pavements. Industry studies have shown adhesion promoters can increase a pavement’s quality lifespan by over 30%. This can be obtained by using as little as one half pound of HPM per ton of asphalt mix. Tests such as AASHTOT-283, ASTM D-4867 or the Hamburg Wheel Test all show significant improvement when using HPM in the mix design. Usual dosage is 0.5 to 1.0% of the weight of the asphalt in the mix. HPM is also less than half the cost of hydrated lime.

Easy and Safe to Use

HPM is a unique, high-performance, low-odor liquid with excellent heat stability that can be added directly into the asphalt cement. It can be added at the asphalt terminal or at a local hot mix plant. Unique’s technical engineers can help you determine the best method for your application or facility. This simple process eliminates product loss as well as lime dust contamination into the atmosphere. HPM has a non-regulated DOT status.
