Methodology for Optimizing Opening of PCC Pavements to Traffic
Due to difficulties associated with the maintenance of highways constructed in urban settings, the expedited construction of durable Portland cement concrete (PCC) pavement has become a necessity. To obtain a durable PCC pavement, a number of parameters should be considered. One important parameter is the adequate curing of a proper mix before opening the road. Since most urban roads experience excessive traffic, the tendency of highway agencies is to open a newly constructed highway to traffic as soon as possible. A rational method to assess the minimum time required to gain a desired strength before opening it to traffic is proposed here. Two reliable and easy-to-use test methods, maturity method and seismic method, are combined to improve the determination of the readiness of a road to be opened to traffic.
