Abstract:A concrete pavement project, complete May 2000 on Interstate 15 near Barstow in San Bernardino County, began to exhibit sighs of premature deterioration. The Office of Rigid Pavement and Structural Concrete was asked to evaluate the situation and make recommendations. Two on-site visits were made to evaluate the status of the concrete. This investigation focused primarily on the concrete mix, weather conditions, and pavement distresses observed on site. A review of construction documents showed the amount of cementitious material in the mix was lower than the amount specified in the project special provisions. Archived weather data indicates the concrete pavement was placed under conditions of warm temperatures, low humidity and high velocity winds. References, 24 figures, 5 tables, 2 appendices, 34 p.
