Download or read book Performance Survey on Open graded Friction Course Mixes written by Gerald Huber and published by Transportation Research Board. This book was released on 2000 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.

Download or read book Strategies for Interim Use of Managed Lanes written by Jodi L. Carson and published by . This book was released on 2005 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although managed lanes will largely function under their intended standard operating procedures, certain conditions (i.e., construction, special events, incidents, or emergencies) may require unusual interim use of the facilities. Because interim managed lane use may detract from the facilities' intended performance, carefully crafted interim use policies should guide these decisions. Given the lack of formal policies or guidelines, variability in observed practices and limited understanding of potential benefits or concerns surrounding interim use of managed lanes (noted through a review of published literature and observed national practice), the objectives of this task were to: (1) discern any positive procedural trends in interim managed lane use that could be recommended for widespread implementation, (2) identify and describe potential benefits and concerns surrounding interim use of managed lanes, and (3) assimilate this information into recommended guidelines addressing all aspects of managed lane facility interim use. This information forms the basis of the recommendations contained in the Managed Lanes Manual developed for TxDOT and FHW A. Following a brief introduction, this report describes motivating conditions and strategies for interim use, general considerations for interim use (i.e., operational and safety effects, public acceptance and perceptions, etc.), and national interim use practice and experience. Based on these findings, recommendations for interim use based on the: (1) severity and nature of conditions; (2) time-of-day, anticipated duration, and traffic impacts; and (3) availability of alternative facilities or strategies are provided. Recommended planning activities and requirements for implementation are also provided.

Download or read book Impact of a Smoothness Incentive disincentive on Hot mix Asphalt Maintenance resurfacing Costs written by Kevin K. McGhee and published by . This book was released on 2006 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smoothness, the absence of bumps and dips in the riding surface of a pavement, improves the quality of the ride and is believed to prolong the life of the pavement. This research addressed the impact of potential pay adjustments for smoothness on maintenance contract prices for hot-mix asphalt. In addition to the construction costs associated with potential incentives/disincentives for smoothness, the research examined the financial value of the resulting product (presumably smoother pavements). The analysis included maintenance cost savings for the owner/agency, as well as any reduction in delay and operating costs for the motoring public. A detailed statistical analysis of 5 years of Virginia's plant mix resurfacing schedules found no statistically definitive impact on bid price as a result of the Virginia Department of Transportation's (VDOT) special provision for rideability for asphalt pavements. A similar analysis on a more focused data set, however, did document a lifetime reduction in the International Roughness Index (IRI) of almost 9 in/mi. This reduction in roughness (increase in smoothness) implies an increase in pavement service life, which translates into reduced annual maintenance costs. Although the analysis supports as much as 7 years in additional functional life, an example calculation demonstrates that just a 2-year life extension will supply approximately $1,295 (about 6% of material costs) in owner/agency savings for every lane-mile of highway that is resurfaced under the special provision for rideability. If VDOT continues to employ the special provision with the frequency it has averaged over the past 4 years (1,033 lane-miles per year), using the special provision will save on the order of $1.3 million per year. The lifetime decrease in roughness can lead to even more dramatic user cost savings. One real example provided in the report demonstrates a fuel cost savings (for trucks alone) of $160,000 over a 10-year period for each lane mile of highway that is resurfaced under the special provision for rideability.
