An epoxy resin system is described which has a good balance of cure time and wetting action as well as the desired durability and color retention. Comments are made on the equipment to handle and place it on a production basis, as well as on maintenance work. In a 1975 demonstration project, 3 variables--temperature, sky cover and surface conditions--were investigated (none of these affected durability), and several problems (coning, adhesion, reflectivity) which were encountered were solved. In a 1976 demonstration project, the following were investigated: bead types and treatment, film thickness variations, surface cleaning, and restriping and overlaying the previous years epoxy with a 10 mil stripe to renew reflectivity. The study concludes that the epoxy will adhere to both portland cement concrete and bituminous pavements, can be placed (with little traffic interuption) as a 20 second hot paint, can withstand heavy traffic and a Minnesota winter season, is economically justifiable, can be placed under a condition (wet pavement) in which other products cannot, and can be cleaned easily.
