Abstract:

The repair of concrete pavement due to utility cuts or deterioration on St. Louis County, Missouri right-of-way consisted of an evaluation of current materials, construction methods and specifications to deliver a durable concrete repair in four to six hours using a concrete maturity meter to determine opening strength. Literature research was performed to improve current four hour opening pavement repair specifications. Material suppliers, contractors and a utility company were consulted on their mixes used. The availability/cost of Type III cement and cold-weather placement was of major concern. The evaluation of contractor, state and county pavement repair mixes, using Type I/II and III cements were tested at the time of placement for concrete temperature, entrained air, and workability. Maturity curves for some common mix designs were constructed to determine the pavement repair’s compressive strength at time of opening. A table of opening compressive strengths based on pavement repair thickness and repair length were adopted. Research concluded that at the time of placement a minimum concrete temperature of 80 Fahrenheit (27 Celsius) is critical in strength gain. The use of non-chloride calcium nitrite-based accelerating and polycarboxylate-based high-range water reducing admixture types were determined and dosages were estimated using locally available aggregate. Specifications were developed to encourage material supplier development of economical ready-mix concrete with Type I/II Portland cement. A procedure was also developed to apply the maturity method to mix design performance and verify the pavement repair’s opening strength is met in four to six hours.
