Abstract Rigid pavement consists of three main layers, the base, sub-base and subgrade. Engineers mainly prefered choosing rigid for heavy load road construction because concrete mixture in this type has advantages terms strength, durability design life. However, also several disadvantages: relatively high maintenance costs. As time goes by, researchers have developed modified mixtures; one the...

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...

Automated detection of pavement boundaries is an important enabling technology in a number of intelligent vehicle applications. Many state of art systems for detecting and tracking pavement boundaries use a priori shape models to describe the appearance of these boundaries. Several types of shape models have been employed, and the model choice is usually made from the standpoint of accommodatin...

Rain drastically modifies the visual environment of road users, particularly at night. It changes visibility through its effects on headlights, windshield, pavement and markings. Rain lessens the performance of headlamps and other light sources by filtering part of their luminous power, thus reducing the illuminance on the roadway ahead of the vehicle. Rain affects the capacity of the driver to...

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...

The Indiana Department of Transportation (INDOT) is currently utilizing a profilograph and the profile index for measuring smoothness assurance for newly constructed pavements. However, there are benefits to implementing a new International Roughness Index (IRI)–based smoothness specification utilizing road profiles measured using inertial profilers. Technological advancements have improved the...
