Is Pavemend™ temperature tolerant?
Pavemend™ can be mixed, poured and reopened under a very wide range of ambient temperatures and climates with little effect on product performance. We have successfully completed projects in ambient temperatures as low as -27°F/-33°C and as high as 140°F/60°C.

Can Pavemend™ bond to the host material?
Pavemend™ bonds tenaciously to all materials except for plastics. Is the only material in the world that we know of that is able to bond to itself without any major surface preparation.

Do Pavemend™ products possess a high early strength?
Pavemend™ products possess high early strengths that allow for quick return to service of critical assets such as runways, gates, roadways and or bridges. We have developed materials with various set times, thus giving the end-user the ability to extend the working time of the material to suit his specific requirement. All of our repair materials achieve more than 2500 psi in three hours with some of our materials achieving compressive strengths in 3000 psi in one hour.

General
Is the product easy to use?
Add water, mix according to the instructions on the side of bucket, pour and finish as required. Unlike concrete, our material reaches it final state by undergoing a chemical reaction. The catalyst for the reaction is water. To start the reaction, add water per the instructions, mix according to the instructions (it is very important that you mix the material thoroughly), and pour. Cleanup is with water. Upon initial set, Pavemend™ can be troweled and broom finished. Upon final set Pavemend™ can be sanded, drilled and polished.

What kind of preparation is needed for the repairs?
Users should follow ACI (ACI 546-96) and/or ICRI (ICRI 03730) recommended practices to attain structurally sound conditions in preparation for repair. The concrete must be clean and rough, all oil, dirt, debris, paint and unsound concrete must be removed. The concrete must be structurally sound, free of defects and have aggregate bonded to the cement matrix. The existing concrete surface requires an open pore structure to absorb the repair material.

Can buckets be split for smaller repairs?
The full unit must be mixed in its entirety to ensure the materials' performs as warranted.

How much water can be used?
Generally for Pavemend™ products design water is one gallon per 45 or 47 lb bucket. Refer to the mixing instructions for smaller units.

Does potable water needs to be used?
We recommend potable water to be used for optimal product performance, but when potable water is not available, our material can mixed with gray, brown and/or salt water.

Is there a limitations to the size of the repair that your material can effectively undertake?
No. One 45lb Pavemend™ container will yield approximately 0.48 cubic feet. Pavemend™ can be layered without cold joints. We have no minimum or maximum repair profile constraints. For larger repairs a mortar mixer can be employed to mix several units at a time.

What are the minimum and maximum profile thickness for Pavemend™?
The minimum profile thickness is a 1/16 in (1.5mm). There are no restrictions to the depth of the repair profile.

When Pavemend™ cures, will it shrink?
Pavemend™ exhibits non-shrink after curing; thereby, maintaining its original seal and fit in the host material.

How does Pavemend™ perform under freezing temperatures?
Pavemend™ experiences zero loss under extended freeze thaw conditions; thereby, maintaining its surface and material integrity for long-term performance.

How does temperatures affect the material?
Ambient temperature affect Pavemend™ less dramatically than traditional materials. In cold temperatures additional mixing is required to reach critical mix temperature. In warm temperatures less mixing time is required. Refer to the mixing instructions for each product for further information.

Can this material be placed in wet conditions?
Pavemend™ can be placed in moist conditions. All standing water needs to be expelled from the repair site prior to placement.

Will Pavemend™ expand during curing?
During cure, Pavemend™ expands very slightly to ensure total contact, establishing micro-pore bond with neighboring materials. Our chemistry allows for an actual bond of our material to the pore structure of the host material, attaining a chemical as well as a mechanical bond with the host materials.

How do you finish this material?
Upon initial set, a surface finish can be applied. Upon final set, our material can be saw-cut, drilled, sanded, and/or polished.

What color does this cure to?
Our standard Pavemend™ products cure to a light gray color. Our materials can be colored to meet customer requirement by simply adding a pigment.

Can Pavemend™ sustain bond integrity to the host material?
Pavemend™ maintains a long term bond to the host material due to its Modulus of Elasticity (MOE), which is specifically engineered to be compatible with typical host materials MOE. MOE describes a material's ability to move. It's that ability to move with the host material that is key to the long-term success of any repair.

What are the post-application steps to ensure integrity of repair?
All pavement/structural design conditions should be maintained or reestablished, to include control joints, sub grade stability, etc. In ambient temperatures below 60°F/15°C, extend loading times by 30 minutes for each 10° below 60°F/15°C.

Are there any additional material handling procedures for temperature extremes?
Pavemend™ 5.0 and Pavemend™ 15.0 are the recommended materials for use in ambient temperatures below 60°F. Water, material, or ambient temperature below 60°F may retard mix or set time. Mix to temperature. Suggested re-trafficking times are based on an ambient temperature of 72°. When conditions are below 60°F additional time is required for proper performance. For every 10°F below 60°F an additional 30 minutes set time is required for proper strength gains.

What about working with rebar?
All Pavemend™ products exhibit exceptional bond strengths to steel. This use extends to reinforcing bars (clean or oxidized). The bond with steel typically exceeds the modulus and design strength limits of the rebar.

Does Pavemend™ require aggregate?
Pavemend™ does not require the use of aggregate extenders. Generally, other products require aggregate extenders due to excessive heat generation when those materials are used to depths of 1-2 inches or more. Pavemend™ can be poured onto an aggregate bed. It will penetrate 1-2 inches before solidifying. Our Pavemend TR™ material can be effectively extended 50% by weight with clean 3/8 inch aggregate.

When can the repair be put back into service?
A minimum of 2000 psi is required for general wheeled traffic. Each product has its own strength curve which determines the time frames for re-trafficking. In ambient temperature below 60°F: Pavemend SLQ™ generally 1.0 hour, Pavemend SL™ generally 1.5 hours, Pavemend TR™ generally 3.0 hours, Pavemend VR™ generally 2.0 hours
