Accommodating oversize and overweight loads: technical report

Accommodating oversize and overweight loads: technical report

Date: July 2012
Creator: Middleton, Daniel R.
Description: "In this report the research project resulted in a statewide map recommending primary and alternate Oversize/ overweight (OS/OW)route networks for the most common origins and destinations based on historical Motor Carrier Division data. Keeping strategic routes open for OS/OW loads and minimizing the number of reroutes along the way will reduce the impedance and unknowns in this critical segment of the motor carrier industry."

Development of Texas Transportation Institute's asphalt compaction monitoring system

Development of Texas Transportation Institute's asphalt compaction monitoring system

Date: July 2012
Creator: Liu, Wenting; Scullion, Thomas & Kassem, Emad
Description: "In recent years, the Texas Department of Transportation has made significant progress with the development and implementation of new technologies to measure the uniformity of new hot mix asphalt layer construction. In Project 0-6992, researchers took this check one step further by developing an accurate global positioning system tracking system for compaction rolling so that the compaction effort applied can be monitored for 100 percent of the new surface. This report presents details of the hardware and software developed in this study. The system was field tested on a number of new overlay projects in Texas."

Full-depth reclamation : new test procedures and recommended updates to specifications

Full-depth reclamation : new test procedures and recommended updates to specifications

Date: July 2012
Creator: Scullion, Thomas
Description: Rehabilitating an old pavement by pulverizing and stabilizing the existing pavement is a process referred to as Full Depth Reclamation (FDR). The stabilized layer becomes either the base or sub-base of the new pavement structure. This process has been used widely for over 20 years in Texas to strengthen and widen structurally inadequate pavement sections. This project developed guidelines on successful FDR practices, developed training materials, and identified areas where improvements to current practices are required. To improve the FDR process, this report includes the following enhancements: (1) As current laboratory testing to select the optimal type and amount of stabilizer takes too long and requires too much material, continue to run parallel testing with the small sample test protocols proposed in this report; (2) Use the falling weight deflectometer (FWD) during construction to validate that the design assumptions are being met; (3) Implement the proposed bond test to select the optimum prime material and amount needed to effectively bond the base to the surfacing materials; (4) Modify the specifications to avoid working in freezing conditions; and (5) Consider implementing the other modifications to specifications proposed in this report.

Guidance on extracting value from Texas Department of Transportation's land holdings

Guidance on extracting value from Texas Department of Transportation's land holdings

Date: July 2012
Creator: Prozzi, Jolanda
Description: "In this report the Center of Transportation Research at The University of Texas at Austin undertook a comprehensive research study to identify and determine when, where, and under what circumstances Texas Department of Transportation (TxDOT) should pursue the implementation of Value Extraction Applications (VEA), and how to effectively recognize and involve key stakeholders."

Laboratory and field performance measurements to support the implementation of warm mix asphalt in Texas

Laboratory and field performance measurements to support the implementation of warm mix asphalt in Texas

Date: July 2012
Creator: Estakhri, Cindy K.
Description: An objective of this study was to monitor the performance of more than 10 warm mix asphalt (WMA) projects in the state. Several WMA technologies were included in the study (foaming, Advera, Evotherm, Rediset, Sasobit) and it was determined that performance of the warm mix was comparable to hot mix. In addition, mix from two warm mix projects were subjected to different curing times and temperatures and then evaluated for mixture volumetrics and performance properties. Results from this study lend support to the current procedures the Texas Department of Transportation has adopted.

Low cost wireless network camera sensors for traffic monitoring

Low cost wireless network camera sensors for traffic monitoring

Date: July 2012
Creator: Huang, Yan & Buckles, Bill P.
Description: Many freeways and arterials in major cities in Texas are presently equipped with video detection cameras to collect data and help in traffic/incident management. In this study, carefully controlled experiments determined the throughput and output quality of various communication configurations. Configurations entailed antennas at several cost levels and it was determined that the least expensive antennas were adequate only for one-hop systems. Via a survey to which 20 districts responded, incidents, volume, and speed were found to be the functionalities most in demand for autonomous surveillance systems. Most systems are monitored by human operators. An alternative to operator-based video monitoring is video analytics. An autonomous traffic monitoring system from a vendor was tested. A demonstration surveillance system was developed and delivered to the Texas Department of Transportation.
