An Investigation Of The Flexural Strength And Toughness Of Hybrid Plain And Fiber Reinforced Concrete For Pavement Applications, Wesley Keys
Graduate Theses and Dissertations
For decades, many solutions have been evaluated to combat cracking in concrete pavements. The study presented in this paper evaluates and compares the flexural performance under a third point loading configuration of plain concrete (PC) beams, fully fiber reinforced concrete (FRC) beams, and hybrid PC and FRC beams, with a top PC and bottom FRC layer. The purpose of this hybrid approach was to provide FRC in only half the section, saving cost, while providing a PC surface layer that is easier to finish. All PC top layers were applied at an age of 7-days, considered a reasonable time for …
Relating The Dongre Workability Test To Cold In-Place Recycled Asphalt Pavements, Gus Williams
Relating The Dongre Workability Test To Cold In-Place Recycled Asphalt Pavements, Gus Williams
Civil Engineering Undergraduate Honors Theses
The Dongre Workability Test (DWT) is a test for determining an asphalt pavement’s relative workability from the stress-strain curve of a sample. While the DWT has seen favorable results with warm mix and hot mix asphalt, Casillas and Braham (2020) attempted to apply this test to cold in-place recycled (CIR) asphalt pavements with limited results. This paper looked at the process of reexamining the DWT method to more favorable results with CIR samples. Phase 1 consisted of defining ten possible metrics from the stress-strain curve and applying them to samples with three different curing conditions. From these preliminary results, the …
Quality Assessment Of Flexible Pavement Automated Cracking Data In Louisiana, Mostafiz Emtiaz
Quality Assessment Of Flexible Pavement Automated Cracking Data In Louisiana, Mostafiz Emtiaz
LSU Master's Theses
Pavement distress survey is the most critical and integral part of pavement management system. Transportation agencies all over the world depends on the accurate pavement distress survey to take major decisions like pavement rehabilitation or reconstruction. Pavement management at the network level requires accurate pavement distress survey to decide the allocation of budget for pavement maintenance, rehabilitation and reconstruction. This study started collected network-level cracking distress data through manual measurements on high-resolution pavement images and the results were used as the ground truth measurements to evaluate the corresponding automated distress data from the Pavement Management System database. Results showed that …
