Most urban areas in the world have water infrastructure systems, including buried sewer and pipelines, which are assessed as need of extensive rehabilitation. Deterioration by many other factors affects structural integrity. Trenchless technologies such Cured-in-Place Pipe (CIPP) now applied numerous projects while minimizing disturbance an environment. The main purpose this study is to develop a high strength CIPP material using various composite materials (e.g., glass fiber, carbon...

Traffic control devices in road construction zones play important roles, which (1) provide critical traffic-related information for the drivers, (2) prevent potential crashes near work zones, and (3) protect crews' safety. Due to number of each site, transportation agencies have faced challenges timely frequently inspecting traffic devices, including temporary devices. Deep learning applications can support these inspection processes. The first step using deep is recognizing zone. This study...

Cured-in-place pipe (CIPP), as a kind of trenchless sewer rehabilitation technology, is method to repair using unsaturated polyester resin. This study develops CIPP liner hot water or steam curing well glass fiber, in contrast traditional methods, which use nonwoven fabric. Composite material samples were fabricated by combining materials various and the structural characteristics liners compared analyzed through short- long-term flexural strength tests. A test was conducted for 10,000 h,...

The number of scan-to-BIM projects that convert scanned data into Building Information Modeling (BIM) for facility management applications in the Mechanical, Electrical and Plumbing (MEP) fields has been increasing. This conversion features an application purpose-oriented process, so Scan-to-BIM work parameters to be applied vary each project. Inevitably, a modeler manually adjusts BIM modeling according purpose, repeats process until desired result is achieved. repetitive manual adverse...

The aging water infrastructure is one ofthe main causes of the increasing pipe breaks nationwide, resulting in significant social and economic costs. To sustain assets good condition, it requires a proactive decision making process for capital improvement project planning, maintenance, rehabilitation replacement. Because physical inspections involve extensive labor financial resources, not always feasible option to cover entire inspection condition assessment. This paper presents two...

Pavement markings play a critical role in reducing crashes and improving safety on public roads. As road pavements age, maintenance work for purposes becomes critical. However, inspecting all pavement at the right time is very challenging due to lack of available human resources. This study was conducted develop an automated condition analysis framework using machine learning technology. The proposed consists three modules: data processing module, marking detection visibility module....

Historically the U.S. transportation system has been continuously improved to adopt new policies and technologies. The vehicle energy transition from fossil fuels electricity is promoted by policymakers major automakers with an expectation of enhancing sustainability aspects such as fuel consumption reduction, carbon emissions lower operations maintenance costs. However, electrification existing infrastructure requires substantial upgrades overcome two concerns ordinary drivers public. One...

Understanding college students' perception of sustainability is paramount as today's students will soon be driving our economy and taking on the responsibility maintaining a sustainable society. This study conducted survey attending two regional universities in United States to capture their current experience levels, expectations, perceptions with regard various aspects utilizing questionnaire consisting structured questions about knowledge/familiarity green product purchase behavior,...

Asset owners and engineers throughout the U.S. world are in search of cost-effective environmentally friendly solutionsthat serve infrastructure issues. One most critical areas concern is wastewater piping structures. It well known that corrugated metal pipes used storm-water structures corroding microbial induced corrosion sanitary sewers various materials results structural concern.Geopolymers have long been to provide enhanced physical performance traditional cementitious binders with...

The consequences associated with pipe failures can be widespread impacting service, while potentially causing damage, affecting traffic, and contaminating water. Recently the visibility of has increased social media 24-hour news coverage. In response, many utilities have adapted asset management strategies to reduce failures. Also, technologies emerged that allow for a more proactive management. As sustainability become focus organizations including utilities, question becomes which strategy...

One of water utility’s managerial challenges is to make a balance in between two distinctive goals, cost-effective provision service and improving customer satisfaction service.
