Jointed Plain Concrete Pavement (JPCP) The spacing between transverse joints is typically about 15 feet for slabs 7 to 12 inches thick. Jointed plain concrete pavements (JPCP) are formed using sections of concrete joined using steel dowels. These dowels are typically coated using an epoxy or other material.
report presents the results of a constructability and productivity analysis for the Caltrans Long Life Asphalt Concrete Pavement Rehabilitation Strategies (LLACPRS), focusing on optimizing the maximum production capability within a 55hour weekend closure. With the assistance of California asphalt concrete paving contractors, the constructability
Strategy of extending concrete pavement service life for as long as possible by arresting, greatly diminishing, or avoiding pavement deterioration processes. Accomplished through: Longlife concrete pavement designs Concrete pavement restoration treatments Overlays to maintain structure and serviceability Build longlife pavements

Expected Service Life for HMA Pavements Final Report February 2005. 22 Figure 16 graphically illustrates the occurrence of different rutting levels for different probabilities. As shown, the average (50 percent probability of occurrence) service life is about 22 years for the moderate level of rut depths.
On December 8, 2010, TRB conducted a web briefing or "webinar" that explored ways to design and construct longlife concrete pavements (LLCP), state experiences implementing LLCPs, and incremental costs of LLCPs.

• Long haul times drive the price of the aggregate too high – Recycled Concrete could be produced on or near the site. • Haul times would have to be cut to minimal levels • Would have to produce recycled at about 50% the cost of Class A – You were capable of producing and paving at an equal rate to conventional paving.
Both asphalt and concrete pavements are designed for 20 years, based on a 20year projected traffic. Asphalt is resurfaced after 814 years, and, in many cases, carry well below the 20year design traffic. Most concrete pavements outlast their design life before 1strehabilitation, and carry much higher traffic than designed for.

After the concrete has reached a required strength, the forms are removed and curing of the edges begins immediately. Joints Control Cracking. After placing and finishing concrete pavement, joints are created to control cracking and to provide relief for concrete expansion caused by temperature and moisture changes.

Evaluation of LongLife Concrete Pavement Practices for Use in Florida Published: Abstract: Current Florida construction practices produce asphalt pavements with a service life of 12 to 20 years before needing rehabilitation; concrete pavements are typically designed for 20 years. However, pavements with much longer design lives are ...
