Hot Mix Asphalt Longitudinal Joint Evaluation, Annette Porter May 2009

Hot Mix Asphalt Longitudinal Joint Evaluation, Annette Porter

Civil Engineering Undergraduate Honors Theses

Longitudinal joints are the portion of the road where two lanes meet and are formed because the lanes are paved at different times. Longitudinal joints tend to be the weakest portion of the roadway, and yet few regulations exist to control their quality. Currently, Arkansas specifications for asphalt pavement do not include any requirements for the measurement of joint quality. The purpose of this research project is to determine the most effective method for evaluating longitudinal joints in hot-mix asphalt (HMA) pavements. Most of the literature concerning longitudinal joints focuses on density as the determining factor of quality because density …

Filterpave Systems, Purdue Ect Team Jan 2009

Filterpave Systems, Purdue Ect Team

ECT Fact Sheets Archive

The need for hard-surfaced porous pavements has grown over the past few years as the market accepts PPS technology as a viable solution, as regulations leave few other options and as frequency of use increases. The FilterPave system is a unique porous pavement system that uses post-consumer recycled glass as the open-graded aggregate. Approximately 90 glass beverage bottles are used in just one square foot of pavement, making constructive use of abundant recycled materials that are traditionally sent to the landfill and used as daily cover.


Structural Behaviour And Analysis Of A Steel-Concrete Balcony Bracket, Sean Carroll Jan 2009

Structural Behaviour And Analysis Of A Steel-Concrete Balcony Bracket, Sean Carroll

Theses

For commonly used moment connections, such as the various types of beam to column endplates, a large amount of information in relation to testing data and suggested design methods exist. Engineers can use this information to safely design such connections. When developing new and unique types of connections however, usually no prior testing information is available to engineers due to the unique design. At the present time, the most effective method of designing and developing any structural element or connection is through testing. Testing and detailed analysis of the results gives factual information on the behaviour of the structure, which …

Quantity-Based Cost Forecasting System For Street Construction Projects, Nipesh Pradhananga Jan 2009

Quantity-Based Cost Forecasting System For Street Construction Projects, Nipesh Pradhananga

UNLV Theses, Dissertations, Professional Papers, and Capstones

Construction projects typically are not withdrawn after going into the competitive bidding process. The decision of contracting authorities regarding which projects will proceed to the bidding stage depends, in part, upon the early estimates of probable cost. Efforts are made to make this estimate as realistic as possible. Irrespective of the estimate of probable cost, the actual project cost is established by the amount of the winning bid.

This study analyzed historical bid data of street construction projects undertaken by the Public Works Department, Clark County, Nevada, from 1991 through 2006. The focus of this study was on utilizing statistical …

Development Of A Problem-Based Learning (Pbl) And Cooperative Learning (Cl) Transportation Engineering Course For Undergraduate Students, Deogratias Eustace Aug 2008

Development Of A Problem-Based Learning (Pbl) And Cooperative Learning (Cl) Transportation Engineering Course For Undergraduate Students, Deogratias Eustace

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This study reports the findings of a project that was done during the implementation of a problem-based learning (PBL) and cooperative learning (CL) elements into an undergraduate transportation engineering course. The study procedure used the student course evaluations, including a survey questionnaire, and university-wide standardized student evaluations. Additionally, student homework, tests, and exam grades were used as part of the evaluation process. Two methods of teaching formats were evaluated: the traditional teaching method of lecturing and using end-of-chapter book questions for homework assignments and the new currently used teaching method of student field data collection, preparation of a lab report …

An Assessment Of The Use Of Structural Deformation As A Method Of Determining Area Of Fire Origin, Andrew T. Tinsley, David J. Icove Jan 2008

An Assessment Of The Use Of Structural Deformation As A Method Of Determining Area Of Fire Origin, Andrew T. Tinsley, David J. Icove

Safety, Security and Emergency Management Faculty and Staff Scholarship

Current methodologies of origin investigation have yet to include the structural deformations seen in steel buildings as a viable indicator of the area of origin of a given fire. As many steel structures are of relatively large size, it is often difficult to determine the area of origin using the typical dig and sift methods advocated in NFPA 921, especially if the extent of the fire was large and there were no witnesses as to the origin of the fire. As has been investigated for years, the performance of steel is highly affected by the application of heat. The science …


Hollo-Bolt®: Blind Connector For Structural Steelwork, Purdue Ect Team Jan 2008

Hollo-Bolt®: Blind Connector For Structural Steelwork, Purdue Ect Team

ECT Fact Sheets Archive

Structural steel connections for connecting to square, rectangular or circular structural tube or to conventional steel where access is available from one side only poses problems. A technology was needed which could provide a quicker and tidier installation than traditional methods such as welding, unsightly strapping or drilling and tapping holes. The invention of the Hollo-Bolt® provided such a solution.


Smartball™: Free Swimming Leak Detection System, Purdue Ect Team Jan 2008

Smartball™: Free Swimming Leak Detection System, Purdue Ect Team

ECT Fact Sheets Archive

Leak detection systems measure ultrasonic noise, infrared temperature variances or electrical flux to detect leakage in structures like, pipes, tanks, geo-membrane retaining structures etc. SmartBall® is a free flowing leak detection system developed by Pure Technologies. It consists of a foam ball that has a smaller aluminum ball at its core. This aluminum core houses an ultrasonic device that sends ultrasonic signals and also collects the reflected sound waves.

Evaluation Of The Role Of Driver’S Knowledge Of Who Has The Right-Of-Way Contributes To Interstate On-Ramp Crashes, Deogratias Eustace, Vamsi Krishna Indupuru Dec 2007

Evaluation Of The Role Of Driver’S Knowledge Of Who Has The Right-Of-Way Contributes To Interstate On-Ramp Crashes, Deogratias Eustace, Vamsi Krishna Indupuru

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

The knowledge of drivers on who has the right-of-way between the one on mainline lanes of a freeway and the one entering the freeway through on-ramp junction lane was evaluated. In addition, drivers’ opinions on how to make the on-ramp junctions safer were collected. A survey instrument with 21 items requesting drivers’ information in regard with demographics, freeway driving experience, knowledge of right-of-way and merging practices was used for data collection. The results show that crashes are relatively rare events and for some reasons, most of them never happen but result into near misses, which can not be reported and …
