Epoxy PE wax powder modifies asphalt. Wax affects all three indicators of asphalt. Asphalt with high wax content has the same grade as asphalt with low wax content. For asphalt, the softening point increases, the ductility decreases, and the penetration increases. The asphalt mixture’s ability to resist water damage becomes worse, its adhesion to the aggregate becomes worse, it is easy to peel off, and high temperatures are prone to rutting.
Similarly, at low temperatures, the asphalt will become brittle and hard, resulting in reduced low-temperature cracking resistance of the pavement and the occurrence of cracks. In addition, wax will cause the adhesion between asphalt and stone. The adhesion is reduced, and in the presence of water, pavement stones will peel off, causing pavement damage. What’s more serious is that waxy asphalt will reduce the skid resistance of the asphalt pavement, affecting the driving safety of the road.
The wax content of asphalt is the wax content that crystallizes and precipitates in a specified solvent and low temperature after the oil is distilled by distillation.
Influence on asphalt mixture pavement:
1. It becomes soft at high temperatures. Therefore, asphalt mixtures mixed with asphalt with high wax content are also prone to softening and have poor high-temperature stability.
2. It becomes hard and brittle at low temperatures and has poor deformation ability under low temperature conditions. Therefore, the asphalt mixture pavement has poor low-temperature deformation ability.
3. The presence of wax can easily cause asphalt and aggregate to peel off (i.e. reduce adhesion).
4. Wax is easily wrapped on the stone surface, reducing the anti-skid performance of the asphalt mixture pavement.
5. The presence of wax will lead to inaccurate indoor test data, thus affecting the quality of asphalt mixture pavement.
Epoxy PE wax powder special polyethylene wax product features:
1. High melting point: high softening point, which can improve the heat resistance of the coating;
2. Fast drying: the coating construction cools quickly, and the construction road can be opened 30% in advance;
3. High hardness: used to protect the coating film, prevent scratches, abrasions and improve wear resistance;
4. Medium viscosity: prevent the hardening and deposition of glass beads and other auxiliary materials, and increase the qualified service life of the coating;
5. High strength: tough, effectively improving the strength of road markings;
6. Good wettability: it can wet titanium dioxide well, give full play to the hiding ability of titanium dioxide, and increase the whiteness of marking paint;
Use scenarios: high and mid-range hot-melt pavement marking paint, hot-melt raised marking paint, hot-melt colored anti-skid pavement, etc.
