Test procedure, materials, mix proportions and construction procedures on the New York Test Road, a part of the Long-Time Study of Cement Performance in Concrete, are described. All 27 of the Long-Time Study cements were used. Performance of the test sections is assessed with respect to durability of the concrete as a material, the only property directly studied in relation to the cement used. Seven and one-half years after the test pavement was completed no one cement proved superior to the others tested. However, the effects of air entrainment in improving resistance of the pavement to scaling and weathering overshadowed all other variables. This report is also found on DVD021.
