PERFORMANCE OF SPECIAL CURING AGENTS AND WATER REDUCING AGENTS ON CONCRETE PAVEMENTS IN COLORADO

In 1970, seven test sections, and their companion control sections, were placed as sections of concrete pavement on northeastern Colorado Interstate routes. There was a test section for each of three water reducing agents on the market at that time, and a test section for an emulsified linseed oil curing compound. There were three test sections for chlorinated rubber curing compounds. After 6-1/2 years of evaluation, the results show that none of the additives or curing compounds provided superior wearing qualities over the product regularly specified for pavement construction by the Colorado Department of Highways. The cost of the water reducing agents would increase the cost of PCC pavements between 1% and 2% with no noticeable improvement in rut prevention for this heavy studded tire environment. The use of chlorinated rubber type of curing compound or emulsified linseed oil curing compounds would increase the cost of pavements between 11found and 31found a square yard, without improving the wear resistance to any measurable extent. /Author/
