Many agencies use the AASHTO Guide for Design of Pavement Structures to design their pavement systems. The limitation inherent in this method is the empirical nature of the decision process, which was derived from a road test conducted almost 45 years ago in Ottawa, Illinois. The newly released Mechanistic-Empirical Pavement Design Guide (MEPDG), based on NCHRP Study 1-37A, has adopted a mechan...

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...

In this paper, a lane detection algorithm is presented by considering geometry information of camera and road. First, the camera geometry information is used to divide the captured image into the road part and non-road part. Then, the histogram of intensity is applied to quantize the road image into a binary image such that the pavement is background and lane mark is foreground. Next, a modifie...

This work develops a method to inspect the quality of pavement conditions based on images captured from moving vehicles. This task is challenging because the appearance of road surfaces varies tremendously, depending on the construction materials (e.g., concrete, asphalt), the weather conditions (e.g., rain, snow), the illumination conditions (e.g., sunny, shadow), and the interference of other...

• Road-pavement surface monitoring, distresses classification and measurement. Comparison of crowdsensing-based monitoring technologies visual inspections. Efficiency effectiveness road-pavement surveys for optimal maintenance. Pavement-surface characteristics should be considered during road maintenance safe comfortable driving. A detailed up-to-date report network conditions is required to op...

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 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...

In today's competitive market, technology transfer is an important problem for firms, organizations and governments. Therefore, making right decisions on selecting a suitable technology and designing an appropriate process to transfer it may have significant influence on the performance of organizations. In this paper, we present a new method to obtain a suitable technology transfer strategy fo...

To measure stiffness of the compacted pavement, practitioners use the Compaction Meter Value (CMV); a ratio between the amplitude for the first harmonic of the compactor’s acceleration and the amplitude corresponding to the vibration frequency. Numerous experiments show that CMV is highly correlated with the pavement stiffness, but as of now, there is no convincing theoretical explanation for t...
