This book was released on 2013 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R06E-RR-1: Real-Time Smoothness Measurements on Portland Cement Concrete Pavements During Construction explores real-time smoothness measuring technologies for concrete paving. For the purposes of the report, real-time smoothness refers to measuring and evaluating the concrete pavement surface profile during construction along the paving train while the concrete surface is still wet. The report also includes draft suggested specifications and guidelines related to the use of technologies that allow paving crews to measure smoothness in real time. The results of Renewal Project R06E will be incorporated into an electronic repository for practitioners, known as the NDToolbox, which will provide information regarding recommended technologies for the detection of a particular deterioration. The NDToolbox is in the process of being created by SHRP 2 Renewal Project R06A, which has released SHRP 2 Report S2-R06A-RR-1: Nondestructive Testing to Identify Concrete Bridge Deck Deterioration that identifies nondestructive testing technologies for detecting and characterizing common forms of deterioration in concrete bridge decks. Renewal Project R06E, which produced SHRP 2 Report S2-R06E-RR-1, is one of seven follow-on projects to SHRP Renewal Project R06 that produced SHRP 2 Report S2-R06-RW: A Plan for Developing High-Speed, Nondestructive Testing Procedures for Both Design Evaluation and Construction Inspection, which examines existing and emerging nondestructive evaluation (NDE) technologies and their current state of implementation to satisfy the NDE needs for highway renewal."--Publisher description.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental composite pavements were constructed at MnROAD in Minnesota and the University of California Pavement Research Center at Davis, where the pavements were instrumented and monitored under climate and heavy traffic loadings. A composite pavement consisting of HMA over jointed plain concrete also was constructed in the field by the Illinois Tollway north of Chicago. At the Tollway, extensive field surveys were performed on 64 sections of the two types of composite pavements. This project also evaluated, improved, and further validated applicable structural, climatic, material, and performance prediction models, and design algorithms that are included in the AASHTO MEPDG and DARWin-ME, CalME, NCHRP 1-41 reflection cracking, NCHRP 9-30A rutting, and the Lattice bonding model.

This book was released on 1990 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to construction engineers, pavement designers, contractors, and others interested in construction of new highway pavements with smooth surfaces. Information is provided on the various devices and specifications that are being used to obtain smooth pavements. The public rates a pavement primarily on its smooth-riding characteristics and highway agencies recognize that constructing smooth pavements results in fewer problems later and lower annual maintenance costs. This report of the Transportation Research Board describes the devices and specifications highway agencies use to ensure that newly constructed pavements will provide a smooth ride.

This book was released on 2007 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: A jointed concrete pavement on I-490 near Rochester, NY, was reconstructed using three different dowel bar spacings in eastbound test sections. Two sections in the westbound direction were instrumented to monitor environmental strain, deflections, and pavement temperatures. Monitoring of the westbound sections was conducted at the time of construction, after 28 days of curing, and at various intervals over the next two years. The instrumentation included deep and shallow linear variable differential transducers (LVDTs) to measure displacements in the center and the corners of the slabs, thermocouples at four depths near the center and at one corner of the slab, and vibrating wire strain gages with built-in thermistors in the center and the left wheel path. Air temperature data were also gathered during monitoring periods. Data were taken from the instruments at the time of construction, and at 37 days (after curing), 12 months, 16 months, and 28 months after construction. In addition to instrumentation readings taken over an approximately 24-hour period, each visit included slab shape measurements made with a Dipstick®, and deflections measured with a falling weight deflectometer (FWD) on the westbound sections. The final data collection visit, in October 2004, also included FWD testing and profilometer measurements on the eastbound sections. In measuring the pavement response, the FWD and LVDT data both indicated some loss of support that varied in response to changing temperature conditions. Of the three dowel bar arrangements, the E2 arrangement that used bars with the smallest cross-section and the narrowest spacing had the best load transfer efficiency.

Download or read book Control of Pavement Smoothness in Kansas written by William H. Parcells and published by . This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement smoothness is a major factor affecting the performance of the highway surface and the safety and satisfaction of the traveling public. Smooth pavement results in better gas mileage, less vehicle wear, and less driver stress and fatigue. Pavement smoothness is the single most important indicator of pavement condition as viewed by the traveling public. Many state highway agencies, including the Kansas Department of Transportation (KDOT), have adopted specifications that set forth a goal of minimal levels of roughness for newly built pavements. Some specifications also include significant incentive/disincentive provisions to encourage contractors to concentrate their efforts on building smooth pavements. This report highlights the development of the smoothness specification for Portland Cement Concrete Pavement (PCCP) beginning in 1985 and for Asphalt Concrete Pavement (ACP) beginning in 1990. The early specifications used the 0.2 inch Blanking Band while evaluating the traces generated using the manual California type profilograph. In 1986, incentive/disincentive clauses allowed bonus payment for PCCP constructed with less than 4 in/mile of surface roughness and penalty (reduced payment) for over 12 in/mile using the 0.2 inch Blanking Band. The implementation of the smoothness specification resulted in dramatic improvement in PCCP smoothness. In 1990 the stage was set for change. The initial projects requiring the use of the profilograph with the 0.2 inch Blanking Band to measure smoothness of ACP provided a high percentage (64%) of bonus level sections thus indicating the need for a modification to the existing specification. Similarly, the PCCP projects built in 1990 also had a high percentage (63%) of bonus level sections while using the 0.2 inch Blanking Band. However, there was one PCCP reconstruction project that had achieved about 47% bonus sections but produced a high frequency vibration in the vehicle when driving at normal speed. A review of the original profilograph traces revealed a short length sine wave roughness that was slightly less than 0.2 inches in amplitude and thus was almost completely covered by the 0.2 inch Blanking Band.
