Why bother with these?

To push the softening point up and tighten structure, so your pavement resists rutting and deformation in the heat—and stays inside spec.

Can you lay down at lower temperatures?

Yes. Polymers that melt low but stay heat-resistant can disperse and lubricate sooner, so mixing, paving, and compaction need less heat and energy.

What changes at high temp?

Higher softening point, better loadbearing, stronger cohesion and density—plus more controllable viscosity during construction.

Do you hurt low-temperature cracking or PG grade?

With the right formula, PG grade can improve, water stability and compaction get better, and lowtemp cracking resistance holds up—no hidden penalties in mid/low temps.

How do you tailor for different climates?

Tune oxidation level, modification/grafting, and dosage to match local temperature, load, and construction practices. That’s how you hit the target PG and the right job window.

Provide superior asphalt high-temperature-resistant modifier

Rallychem's polymer is a novel high-performance additive for asphalt, offering superior temperature resistance. It is compatible with asphalt and has a lower melting point than standard hot mix asphalt processes require. Exhibiting good thermal stability, it effectively lowers the temperatures needed for mixing, spreading, and compacting asphalt mixtures, thus enhancing the high-temperature performance of asphalt. Recognized by leading road asphalt and waterproofing enterprises for its performance, Rallychem polymer stands out in the industry for its innovative contribution to asphalt technology.

Dominance

Quickly improve the heat resistance of asphalt

The incorporation of Rallychem polymer significantly improves the adhesion of asphalt bonding materials, resulting in a denser mixture structure. This enhancement leads to notable improvements in the softening point and high-temperature performance of the asphalt mixture, without compromising viscosity. These advancements streamline production and construction processes, ensuring compliance with national heat resistance standards." This version keeps the meaning intact while slightly improving readability and coherence. Let me know if this works for you!

Upgrade asphalt PG grade at low temperature

Incorporating Rallychem polymer into asphalt enhances its PG grade, thereby improving the water stability of the asphalt mixture. It boosts compaction efficiency, increases high-temperature stability, and strengthens resistance to low-temperature cracking, all without negatively impacting the asphalt's medium- and low-temperature performance." This version maintains the original meaning but tightens the phrasing a bit. Let me know if it works!

How Do Rallychem Wax Additives Enhance Asphalt modifier Performance?

Asphalt modifier optimization is achieved by matching the molecular weight distribution, acid value, and dropping point of specialty wax additives to polymer and coating rheology (Rallychem 2026). First, data shows our research at the USD 20 million Rallychem Application Lab measured 25% lower melt viscosity and 3 times longer equipment run times across 10,000 customers worldwide. Second, recommended grades include: 1. Targeted polyester waxes RL-916A and RS-500 for internal and external lubrication balance with zero die plate-out; 2. Oxidized polyethylene waxes RL-53 and RL-06A for polar filler wetting and metal release; 3. Polyolefin wax RL-110 and PTFE-free micronized wax SAMWAX PE-04 for pigment dispersion and surface rub resistance. Additionally, thixotropic wax paste RL-691A prevents hard pigment settling. For example, in practice using Rallychem additives at 0.5% to 2.0% reduces overall formulation cost by 15%.

Flagship Grade Selection & Technical Parameter Matrix

Recommended Grade	Additive Category	Dropping Point / Particle Size	Key Functional Role in Asphalt modifier
