Description
D.O.T.Line™ is an extremely versatile, cementitious, rapid setting, semi-leveling structural repair concrete. It is a single component powder that is water activated. D.O.T.Line™ has 25 minutes of working time and will reach compressive strengths of more than 2,500 psi within 2 hours from the addition of water. D.O.T.Line™ can be applied in ambient temperature ranges from 30 to 120 degrees Fahrenheit. D.O.T.Line™ finishes like traditional Portland based concrete and cleans up easily with water. D.O.T.Line™ rapid repair concrete offers all of the performance and ease of use characteristics associated with CERATECH’s Pavemend™ High Performance Repair Products, in a low cost,turn-key, aggregate extended package.
Recommended Uses
D.O.T.Line™ has been designed for horizontal applications providing for cost effective structural repair of roads and bridges.

Site Preparation
Surfaces should be prepared in accordance with ICRI 03730, “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.” and / or ACI 546R-96 “ Concrete Repair Guide” Concrete surface should be prepared by appropriate mechanical methods to obtain an exposed aggregate surface with a minimum surface profile of +/- 1/16” (1.5 mm) in accordance with ICRI 03732. Pre-existing coatings or surface treatments should be completely removed. Dry, clean, stable surfaces are required. Remove all standing water. Reinforcing steel should have no loose scale. Surfaces of host concrete must be damp.
Standard Mixing Procedures (Rotating Drum Concrete Mixer)
- Pre-wet cement mixer with water then drain all water from mixer (away from repair area)
- Start mixer - D.O.T.Line™ requires a total of 2 quarts of water per 53.5 lb. unit. Initially, add only 1 quart of water to concrete mixer per 53.5lb unit of D.O.T.Line™ to be used.
- Add pre-determined units of D.O.T.Line™, mix for 1 minute
- Add in remaining quart of water per unit of D.O.T.Line™
- Mix for 6 additional minutes or 7 minutes total
- Pour all contents into repair area
- Clean mixer or repeat process for next batch
NOTES:
D.O.T.Line™ is a water to binder sensitive cement. NEVER use less than 2 quarts of water nor MORE THAN 2 1/8 quarts of water per 53.5lb unit of DOTLine™.)
- In ambient temperatures, < 50°F/10°C, use warm water from 70°F/22°C to 90°F/32°C
- In ambient temperatures > 85°F/29°C, use cooler water from 50°F/ 10°C to 60°F/16°C
- Working times will vary when mix water temperature’s are outside of these recommendations
- Minimum recommended batch size is 2 units ( Use 4 quarts of water for 2 bag batches)
Application and 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.
- Minimum profile thickness is 1.25” (3.2 cm). There are no restrictions to the depth of the repair profile.
- For best results, CERATECH recommends monolithic placement of repair materials. Maintain a minimum thickness of 1.00 inch 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. In ambient and/or surface temperatures below 32°F/0°C, extend the loading time by 60 minutes for each 10° below 32°F/0°C.
- 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).
- Clean all tools and equipment with water prior to the material reaching final set.
