Abstract Pavement structure can be designed either as a flexible or rigid pavement based on its structural behaviour, with pavements being frequently favored due to advantages. One of the major problems that normally occurred in road construction was distresses quality materials. Numerous studies were carried out explore sustainable ways improve performance especially modification asphaltic con...
Cracking is one of the main distresses in asphalt pavement. At present, few studies have been conducted on cracking performance mixtures from field due to difficulty sample collection. Therefore, this study aims assess resistance in-service pavement at intermediate temperature using a large number cores Jiangsu province, China. A semi-circular bending (SCB) test 25 °C was field-cored samples co...
Monitoring of critical civil engineering infrastructures has become a priority for public owners and administrative authorities. Several laws regulations have been issued on this topic, emphasizing the crucial role Building Information Modeling (BIM)- based procedures design management infrastructures. This study aims at examining potential an interoperable upgradeable BIM model supplemented by...
Automating pavement maintenance suggestions systems is challenging, especially for actionable recommendations such as patching location, depth, and priority. It a common practice among state agencies to manually inspect road segments of interest decide requirements based on the condition index (PCI). However, standalone PCI only evaluates surface which, coupled with variability in human percept...
Purpose The massive number of pavements and buildings coupled with the limited inspection resources, both monetary human, to detect distresses recommend maintenance actions lead rapid deterioration, decreased service life, lower level increased community disruption. Therefore, this paper aims at providing a state-of-the-art review literature respect deep learning techniques for detecting distre...
Respiratory distress by laryngospasm as an isolated manifestation of epileptic seizure is rare phenomenon. We report on a 1-month-old infant with recurrent respiratory distresses by laryngospasm as an isolated manifestation of status epilepticus and resultant periarrests, while being monitored in our intensive care unit. This case of an atypical manifestation of status epilepticus highlights th...
Concrete overlays are a growing solution in the United States for pavement rehabilitation and preservation. Many different overlay types designs can be used based on existing conditions to achieve variety of design goals. Recent performance studies have indicated that concrete capable providing an extended service life 35 years or more. However, intended may shorter, some cases, experience earl...
Rutting is one of the most common distresses in early damage to asphalt pavements. It can raise risk ride safety issues, accelerate pavement deterioration, and increase maintenance costs. To investigate factors that affect rutting resistance mixtures, internal (such as aggregate gradation, content, layer thickness), external (including temperature traffic loading), human compaction degree) were...
We present a novel deep learning framework named the Iteratively Optimized Patch Label Inference Network (IOPLIN) for automatically detecting various pavement distresses that are not solely limited to specific ones, such as cracks and potholes. IOPLIN can be iteratively trained with only image label via Expectation-Maximization Inspired Distillation (EMIPLD) strategy, accomplish this task well ...
