Book Synopsis Best Practices for Chip Sealing Low-volume Roads in Ohio by : Roger Green
Download or read book Best Practices for Chip Sealing Low-volume Roads in Ohio written by Roger Green and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lack of funding and a desire to effectively manage the pavement network has resulted in the widespread use of chip seals by local agencies in Ohio. With the 2002 Construction and Materials Specifications (CMS), the Ohio Department of Transportation's (ODOT) made major revisions to the chip seal specification to incorporate best practices applicable for pavements on the state highway system. However, the new specification may be burdensome and costly for local agencies to adopt due to lack of inspection personnel and a required level of quality which may not be necessary to achieve satisfactory performance on the local system. Many local agencies construct chip seals using local work crews and application rates based on experience, or with contractors using local specifications or older version of the ODOT specification. Consequently, success has been varied, with some excellent applications and some failures. The purpose of this research was to gain a better understanding of chip seal practices of the local agencies and identify best practices for low traffic volume roads. The goal of this research was to assess the current state of practice for chip sealing on county, township, and municipal-maintained roads. The objective was to develop a matrix of best practices for chip sealing low-volume roads in Ohio and design a study to aid in the future assessment of long-term performance creating protocols for data collection. As part of this study a literature review was completed, county and municipal engineers, and township trustees were surveyed regarding their chip seal practices, and follow-up interviews were conducted with eleven agencies. Based on the information collected a matrix of best practices for chip sealing on local roadways was developed and a study to collect long-term performance was designed. The best practices matrix identifies best practices as defined in the literature and by local agency personnel and is provided in this report. A plan and data collection software for a long term monitoring and evaluation of chip seals is also provided.

Book Synopsis Design and Evaluation of Chip Seals Through Image-based Microstructural Parameters and Performance Tests by : Yogesh Shamsunder Kumbargeri
Download or read book Design and Evaluation of Chip Seals Through Image-based Microstructural Parameters and Performance Tests written by Yogesh Shamsunder Kumbargeri and published by . This book was released on 2019 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chip seal is one of the most popularly adopted pavement preservation strategies. A chip seal treatment is constructed by adding hot asphalt or emulsion on the surface of an existing pavement, spraying aggregates on the top, followed by roller compaction. Extensive research has led to the formulation of various chip seal analysis and design methodologies. These methods are mostly empirical in nature and depend on numerous assumptions related to chip seal microstructure and their expected behavior after compaction in field. Hence, there is a need for in-depth analysis of chip seals to develop performance-based design methods addressing the primary distresses as well as the microstructural parameters such as percent embedment and aggregate orientation. The objective of this research study was to evaluate chip seals through image-based microstructural parameters and performance tests. The results of a comprehensive experimental program lead to development of a holistic approach to chip seal design, encompassing various aspects of chip seal performance through aggregate-binder microstructural perspective. New image processing techniques were developed to understand the percent embedment and aggregate orientation behavior. Additionally, finite element analyses were performed using actual chip seal images to evaluate mechanistic characteristics (e.g., magnitudes of strains at the aggregate/binder interface) responsible for chip seal performance. Further, extensive performance tests were run in laboratory to evaluate the effect of design parameters (e.g. percent embedment, aggregate orientation) on chip seal performance distresses (aggregate loss and bleeding). The results were combined and analyzed to yield new insights into effect of microstructural parameters on chip seal performance. Furthermore, a performance-based design procedure was developed for design of chip seals. This procedure integrates the chip seal microstructural behavior and its performance.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Synopsis Chip Seals for Asphalt Concrete Pavements by : Denise Hoyt

Book excerpt: Chip seals are a pavement surface treatment used for maintaining asphalt concrete pavements. National Cooperative Highway Research Program (NCHRP) Project 14-17 was performed to produce a national Chip Seal Manual which would consolidate the best chip seal engineering practices. A subcontract to NCHRP Project 14-17 performed at Texas A & M University was the basis for this thesis. It included the following tasks: investigation of a testing and grading system for grading asphalt binder residues from chip seal emulsions; and investigation of texture measurement methods for assessing existing pavement macrotexture before a chip seal is placed. The performance graded (PG) asphalt binder specification, which was developed to characterize asphalt binder properties related to the performance of hot mix asphalt concrete in pavements, cannot be directly applied to asphalt binders or emulsion residues for use in chip seals. Therefore, the surface performance graded (SPG) specification was developed using the same equipment as the PG system but with some procedural modifications and different limiting values for the test parameters. NCHRP Project 14-17 utilized the PG and SPG systems to grade base asphalt binders and recovered emulsion residues. Two emulsion residue recovery methods were compared: hot oven evaporation with nitrogen blanket and stirred can with nitrogen purge. The PG and SPG grades were found to be similar for the two emulsion residue recovery methods but slightly different from the base asphalt binder. A strawman specification for emulsion residues in chip seals was recommended for use with the stirred can recovery method. In chip seal construction, macrotexture of the existing pavement affects the rate at which chip seal emulsion must be applied. In this project, existing pavement macrotextures were measured at three chip seal projects immediately before construction using both the sand patch test and the circular track meter, CT Meter. The CT Meter was found to quickly and effectively measure pavement macrotexture. The CT Meter measurements correlated well with the sand patch test measurements. Finally, this project investigated the utility of measuring pavement macrotexture in the laboratory using the aggregate imaging system (AIMS) on pavement cores and on small samples cut from fabricated slabs. Statistical analyses showed good correlation between the mean profile depth, MPD, calculated from AIMS measurements on pavement cores and small samples, based on analysis using 50 mm (2 inch) segment lengths, and the MPD measured on the pavement or on the large fabricated slabs with the CTMeter. These results supported the use of AIMS to measure pavement macrotexture using small samples in the laboratory.
Book Synopsis Performance Evaluation of Chip Seals for Higher Volume Roads Using Polymer-Modified Emulsions by : Jeong Hyuk Im
Download or read book Performance Evaluation of Chip Seals for Higher Volume Roads Using Polymer-Modified Emulsions written by Jeong Hyuk Im and published by . This book was released on 2015 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presented a study to evaluate the performance of chip seals for higher traffic volume roads. The evaporation test, bitumen bond strength (BBS) test, and Vialit test were used to investigate curing and adhesive behavior. For the laboratory performance, the third-scale model mobile load simulator (MMLS3) was employed to test for aggregate retention, bleeding, and rutting performance. In field, a total of ten test sections were constructed on three different traffic volume roads using different materials and seal types. Some of the field samples were extracted and moved to the laboratory for performance testing. Also, the field sections were monitored to compare the field performance with the laboratory performance. The main findings presented in this paper were as follows: (1) the laboratory test results indicated that the use of polymer modified emulsions (PMEs) improved the chip seal performance in all areas, i.e., curing and adhesive behavior, aggregate retention, bleeding, and rutting; and (2) the field observations indicated that PME-A (styrene butadiene styrene (SBS) polymer-modified emulsion) performs the best of all the emulsions, regardless of seal type and traffic volume.
