Concrete is one of the most widely used construction materials all around globe. Associated with urban expansion, concrete pavements increase impermeable surfaces that affect hydrological cycle and generate heat islands. Cement main components concrete, its production sources worldwide CO2 emissions. Pervious partial cement replacement represents a more sustainable alternative. In this paper, u...

Portland cement concrete (PCC) pavement undergoes repeated environmental load-related deflection resulting from temperature and moisture variations across pavement depth. This has been recognized as resulting in PCC pavement curling and warping since the mid-1920s. Slab curvature can be further magnified under repeated traffic loads and may ultimately lead to fatigue failures, including top-dow...

The mission of the National Concrete Pavement Technology Center is to unite key transportation stakeholders around the central goal of advancing concrete pavement technology through research, tech transfer, and technology implementation. The contents of this report reflect the views of the authors, who are responsible for the facts and the accuracy of the information presented herein. The opini...

Three dimensioned finite element analysis were conducted on concrete block paving. In order to verify the calculated results, an experimental case study was analyzed. Good agreement was observed between the measured and the calculated results. Based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance models and the associated AASHTOWare® Pavement ME Design software are nationally calibrated using design inputs and distress data largely from the national Long-Term Pavement Performance (LTPP). Further calibration and validation studies are necessary for local highway agencies’ implementation by taking into acc...

Portland cement concrete has been used extensively for many years as a construction material in bridges, buildings, highway pavements and other structures. Numerous structures and pavements that have been in service for decades illustrate the good durability and value of con­ crete when properly used in engineering construction. For example, the first concrete pavement built in the United State...

Impervious pavement surfaces within urban areas present serious environmental problems due to waterlogging, flooding and in particular, the heat island (UHI) phenomenon. Another issue that has recently been highlighted is user comfort pedestrian cycling areas. Materials have potential for overcoming these issues include pervious concrete (PC), a new type of construction material with improved d...
