Bad Weather Installation

Asphalt Anchors can be installed in rain, heat, and cold within the limits of the selected adhesive. Installation temperature affects adhesive handling and curing; pavement temperature while the cured anchor is under load affects its pull capacity.

RAIN & WET

EPX3 and EPX5 can be used in wet and standing water.

EPX2 must be installed in dry conditions. While the EPX2 is waterproof once it hardens, rain can dilute the grout mixture when poured into the hole. This can be caused by standing water in the hole, or by water seeping into the hole from the rain or from a high water-table in the area. If you are unable to fully dry the hole, use the EPX3 instead.

COLD TEMPERATURE

EPX2 adhesive uses water in the mix. If the ambient temperature is below 50F, use warm water in the mix, then quickly dispense the mix into the hole. EPX2 can not be installed below 40F.

EPX3 adhesive can be installed down to 14F. However, you need to pre-heat the EPX3 adhesive package to 70F before using it. If the EPX3 is used cold (below 50F) it will take much longer to cure, and at subfreezing epoxy temperature the curing will not even start. Once the curing starts it is exothermic and will self sustain in most temperatures.

EPX5 is the same as EPX3, but only useable down to 24F.

HOT TEMPERATURE

Warm weather significantly speeds up the curing process of all of our adhesives. To ensure the adhesive has sufficient working time, keep the adhesive shaded and cool at all times. For EPX2, you can work in ice water during mixing. For EPX3 or EPX5, keep the cartridge in a cooler/fridge until use.

Hot pavement can reduce anchor capacity

Heat affects the asphalt surrounding the anchor, not just adhesive installation and curing. In our Sonoma testing on PG64-16 pavement, measured pull capacity declined approximately 10–15% for each additional 10°F above an 80°F pavement temperature.

This result is specific to the tested pavement. Binder grade, mix design, pavement condition, and temperature through the anchor depth can materially change performance. Do not treat this relationship as a universal derating rule. For critical applications exposed to pavement temperatures above 80°F, use site-specific pull testing or contact us for guidance.
