Recently developed Mechanistic-Empirical Pavement Design Guide (MEPDG) determines the probable total rutting by summing up the deformations of all layers of the trial pavement. If all distresses outcomes including rutting are within the specification the trial section is designed for construction. Therefore, vertical deformation (or strain) needs to be measured to validate the MEPDG for local c...

The main role of the present work is to conduct pavement performance evaluation of Cell Filled Concrete road constructed in Sidlaghatta taluk of Chickaballapura District in Karnataka. The study area selected is from Anur Hunasenahalli to T-07 (2.16 km) in Sidlaghatta Taluk. The above selected road is categorized under Village Roads (VR) and is constructed under the Technology Demonstration Proj...

Roadway pavement surface distress information is critical for effective pavement asset management, and subsequently, transportation management agencies at all levels (i.e., federal, state, and local) dedicate a large amount of time and money to routinely evaluate pavement surface distress conditions as the core of their asset management programs. However, currently adopted ground-based evaluati...

Initiatives are underway to implement the new Mechanistic-Empirical Pavement Design Guide (MEPDG) in Iowa. This paper focuses on the sensitivity study of Jointed Plain Concrete Pavements (JPCP) and Continuously Reinforced Concrete Pavements (CRCP) in Iowa using the MEPDG software. In this comprehensive study, the effect of MEPDG input parameters on the rigid pavement performance is evaluated us...

An accurate and regular survey of the road surface distresses is a key factor for pavement rehabilitation design and management, allowing public managers to maximize the value of the continuously limited budgets for road improvements and maintenance. Manual pavement distress surveys are labor-intensive, expensive and unsafe for highly-trafficked highways. Over the years, automated surveys using...

Government agencies and consulting companies in charge of pavement management face the challenge of maintaining pavements in serviceable conditions throughout their life from the functional and structural standpoints. For this, the assessment and prediction of the pavement conditions are crucial. This study proposes a neuro-fuzzy model to predict the performance of flexible pavements using the ...

This study develops and tests an automatic pixel-level image recognition model to reduce the amount of manual labor required collect data for road maintenance. Firstly, images six kinds pavement distresses, namely, transverse cracks, longitudinal alligator block potholes, patches, are collected from four asphalt highways in three provinces China build a labeled dataset containing 10,097 images....

asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...

Suitable evaluation of distress is beneficial to understanding the in situ performance deck pavement. This study attempts evaluate long-term American ChemCo epoxy asphalt concrete on Xihoumen Bridge (XHMB) after 12 years service. The traditional indexes were adopted reveal XHMB. Then, based typical distresses, a new pavement index (PPI) was proposed characterize authentic condition. Finally, an...
