General Charateristics: DOTLine is fiber reinforced, rapid setting, self-consolidating, cementitious based structural repair concrete. It is a single component powder that is water activated. DOTLine has 20 - 25 minutes of working time and will reach compressive strengths of more than 2500 psi within 2 hours from mixing. DOTLine can be applied in ambient temperature ranges of 40°F to 120°F. DOTLine finishes like traditional Portland based concrete and cleans up easily with water. DOTLine rapid repair concrete offers high performance and ease of use in a cost effective, turn-key, pre-extended package. Typical Applications: DOTLine has been designed for horizontal applications providing for cost effective structural repair of roads, bridges, airport runways, and form & pour projects. Can be used as a temporary repair for asphalt pavement. Site Preparation: • Substrates must be of load bearing capacity, and free from all potential bond breakers such as dirt, dust, grease, oil, sealers, curing compounds, laitance, loose or deteriorated concrete and any bond-inhibiting foreign substances. • Mechanically prepare surfaces to achieve a surface profile equal to CSP 5 – 7. Concrete Surface Profile as per ICRI Guideline No. 310.2-1997 (Formerly Guideline No. 03732) • All surfaces to be repaired should be saturated surface dry (SSD) but have no standing water. Hot surfaces should be cooled and shaded while cold surfaces should be heated and sheltered.Mechanically remove all loose materials by suitable means such as chipping hammer, chisel, sandblast, high pressure water blast (>5000 psi), or similar methods. Mixing Instructions: Standard Mixing Procedures (Rotating Drum Concrete Mixer). Mix at least 2 units at a time (Use 4 quarts of water for 2 bag batches).: 1. Pre-wet cement mixer with water then drain all water from mixer (away from repair area). 2. Start mixer - DOTLine requires a total of 2 quarts of water per 53.5 lb. unit. Initially, add only 1 quart of water to concrete mixer per 53.5 lb unit of DOTLine to be used. 3. Add pre-determined units of DOTLine, mix for 1 minute. 4. Add in remaining quart of water per unit of DOTLine. 5. Mix for 6 additional minutes or 7 minutes total. 6. Pour all contents into repair area.
DOTLine is tested according to ASTM C928 Results provided by licensed engineering test laboratory and represent typical results from production materials. Actual results may vary from third party testing results; however, Pavemend materials meet and/or exceed ASTM C928, and exceed established internal quality control standards, (available upon request). All samples were air cured.

7. Clean mixer or repeat process for next batch NOTES: • In ambient temperatures, < 40°F / 10°C: use warm water (70°F/22°C to 90°F/32°C). • In ambient temperatures > 85°F/ 29°C: use cooler water (50°F/ 10°C to 60°F/16°C). • Working times will vary when mix water temperature’s are outside of these recommendations.

Pavemend DOTLine™ Application & Finish: Surfaces of host concrete must be damp with no standing water. • Working times based on ambient temperature, types of aggregate and total amount of water. Working times are influenced by surface temperature and repair profile. Working time can be extended by adding Aquafin’s Set Retardant Admixture to mix water. (See Set Retardant product data sheet for more information). • Minimum profile thickness is 1.25” (3.2 cm). There are no restrictions to the depth of the repair profile. • For best results, Aquafin recommends monolithic placement of repair materials. Maintain a minimum thickness of 1” if repair material must be layered. Material must also be layered before final set has been reached. • Upon initial set, a broom finish can be applied. Upon final set, the material can be saw-cut, drilled, sanded and/or polished. • Do not re-temper. The addition of water to the surface of the repair will negatively affect the materials final properties. • General loading in 2 hours for wheeled traffic and 1 hour for foot traffic after addition of water. Add 30 minutes for every 10°F drop in temperature. Contact Aquafin Field Engineering for Cold Weather Applications (40°F/4.5°C and below). • All previously existing joints must be re-established within 2-3 hours of final set. • Self-curing, (Protect with blankets or equivalent in ambient temperatures below freezing (32°F / 0°F), water curing not required or recommended. • Clean all tools and equipment with water prior to the material reaching final set. Limitations: • Not recommended for surface temperatures above 120°F/49°C or below 40°F/10°C. (Contact Aquafin Tech support for temperatures below 50°F).
