Book excerpt: Pavement deformation of hot mix asphalt mixtures (HMA) is one of the major distresses affecting pavement performance. With the current Superpave mix design method, there is no strength or permanent deformation testing of the HMA mixture. The objectives of this study were to evaluate KDOT mixtures, obtained from in-place pavements, at various test temperatures and rutting cycles in the Asphalt Pavement Analyzer (APA) and develop a test method to evaluate the rutting potential of Kansas mixtures. Six different pavements in Kansas with heavy truck traffic were sampled for testing and evaluation.

Book Synopsis Effect of Segregation on Hot Mix Asphalt Using the Asphalt Pavement Analyzer by : Stephen Alan Cross
Download or read book Effect of Segregation on Hot Mix Asphalt Using the Asphalt Pavement Analyzer written by Stephen Alan Cross and published by . This book was released on 2000 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Segregation of hot mix asphalt is a recurring problem in the paving industry. There is little documented research that quantifies the effects of segregation on mix properties and performance. The Asphalt Pavement Analyzer (APA) is a new class of pavement tester available to evaluate pavement performance. The APA can evaluate the rutting potential, moisture susceptibility and fatigue life of bituminous mixtures. Materials were available from a previous study (K-TRAN: KU-96-6) on segregation for use in evaluating the use of the APA with Kansas mixtures and materials. Two surface mixes, a BM-1B and BM-2, were fabricated to different levels of segregation as determined in the K-TRAN: KU-96-6 study. The mixtures were tested in the APA for rutting, moisture damage and fatigue life.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) is currently using the asphalt pavement analyzer (APA) as a testing tool to screen the rutting potential of asphalt mixtures as part of its balanced mix design (BMD) method. However, the cost and availability of APA equipment in VDOT and contractor laboratories and the speed of testing are main barriers to the routine use of APA in the BMD process, especially during the production of asphalt mixtures. The existence of alternative tests that are simple, practical, and performance indicative can help facilitate the implementation of BMD into practice. The monotonic loading tests (hereinafter “monotonic tests”) have been proposed to address the need for simpler tests. This study was undertaken to assess the feasibility of using monotonic tests as a screening tool to evaluate the rutting potential of dense-graded asphalt surface mixtures as part of the BMD initiative in Virginia. In this effort, three monotonic tests, the indirect tensile at high temperature (IDT-HT) test, rapid rutting (RR) test, and Marshall stability and flow (MS) test, identified from the literature, were evaluated using 17 plant-produced asphalt mixtures with “A” and “D” designations. The results were used to assess the monotonic tests and the APA test relative to each other through several performance metrics and correlations with fundamental rutting tests and mechanistic-empirical–based simulations. The results were also used to develop performance threshold criteria for the considered tests. The results showed that the IDT-HT and RR tests can be used to screen the rutting potential of asphalt mixtures meeting VDOT mixture volumetric and gradation requirements for the A and D mixtures. The initial performance criteria for the IDT-HT and RR tests were established for these mixtures. Based on the results, the IDT-HT test was found to be the most suitable alternative test to the APA test. The study recommends using the IDT-HT test as part of the BMD initiative with a corresponding minimum strength of 133 kPa as a performance criterion based on the testing conditions used in this study. Implementation of traffic-based performance criteria for the A and D mixtures should be explored, as the current practice does not differentiate the performance between these mixtures. The results of the IDT-HT, RR, and the APA tests should be compared and correlated with those from fundamental rutting tests and with performance predictions obtained from mechanistic-empirical pavement design simulations using a larger number of mixtures to verify the findings of this study. In addition, the results should be compared to field performance results for full assurance that the implemented tests and associated threshold values are appropriate. Fine-tuning the testing process for the IDT-HT, RR, and APA tests and establishing precision estimates and statements are necessary for proper quality assurance practices. The study further recommends hands-on training and demonstration of the tests being considered by VDOT as part of the BMD implementation.

Download or read book Laboratory Evaluation of Rutting Potential of Asphalt Mixtures written by TF. Fwa and published by . This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a laboratory procedure to evaluate the rutting potential of asphalt mixtures using a wheel tracking machine. Moving loads were applied through solid rubber tired wheels that travel with a reciprocating motion on slab specimens of asphalt mixtures. The specimens were prepared in parallepipedal steel molds by means of static compression to achieve fairly uniform density distribution within individual specimens. The machine allows rut tests to be conducted at different temperatures, magnitudes of applied loads, and speeds of loading. Results of a test program are reported to illustrate the application of the procedure to study the effects of temperature and loading speed on rut development in an asphalt mixture.

Available in PDF, EPUB and Kindle. Book excerpt: Permanent deformation, or rutting, has been and continues to be a problem in the performance of hot mix asphalt (HMA) pavements. This paper presents a summary of work conducted under National Cooperative Highway Research Program (NCHRP) Project 9-17. This research project was undertaken to evaluate the Asphalt Pavement Analyzer (APA) to determine its suitability as a general method of predicting rut potential. There was a need to identify test conditions within the APA that produced results most related to field rutting performance. Ten HMA mixes of known field rutting performance were tested within a full factorial experiment designed to determine the combination of testing conditions for the APA that best predicts field rutting. The experimental plan consisted of different specimen types (beam and cylinder), air void contents in compacted test specimen (4 and 7 %), hose diameters (25 and 38 mm), and test temperatures (high temperature of standard PG grade based upon climate and 6°C higher temperature). Based upon the test results and analysis, a tentative standard method of test was developed and recommended. A standard practice for establishing maximum specified rut depth for APA by highway agencies has also been recommended.
Book Synopsis Evaluation of Cold In-place Recycled Mixtures on US-283 by : Stephen Alan Cross
Download or read book Evaluation of Cold In-place Recycled Mixtures on US-283 written by Stephen Alan Cross and published by . This book was released on 2000 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Kansas Department of Transportation (KDOT) by cold in-place recycling (CIR) recycles approximately 120 to 160 km of pavement a year as a part of their 1-R maintenance program. Originally KDOT utilized asphalt emulsions (AE) as the additive in CIR mixtures, but based on performance concerns currently utilizes type C fly ash. Recent research indicates that the use of CIR with asphalt emulsion and hydrated lime, introduced as hot slurry, provides improved performance. KDOT constructed two test sections on US-283 using type C fly ash and CSS-1 with hot lime slurry and type C fly ash. Two additional asphalt emulsions were evaluated as well, CMS-1 and HFE-150. The cores and laboratory samples were tested for tensile strength, AASHTO T283, resilient modulus and for rutting resistance and moisture damage using the Asphalt Pavement Analyzer (Georgia Rut Tester).

Download or read book Laboratory Evaluation of Rutting in Asphalt Pavements written by Khaled Ksaibati and published by . This book was released on 1996 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated in this research. The research was performed in two phases. The first phase consisted of modifying the GLWT to handle 15.2 cm (6 in) cores, developing a laboratory compaction procedure for cores, determining the optimum laboratory testing conditions, and investigating the repeatability of the GLWT. The second phase of the study included correlating rut depth values obtained with the GLWT to actual field rut depth values, utilizing the GLWT to evaluate the effects of the asphalt additive SOMAT on asphalt concrete mixes, and evaluating the rut resistance of Stone Matrix Asphalt (SMA). Results from the study show that the GLWT is capable of predicting rutting in asphalt pavements prior to construction. In addition, results from the GLWT correlate well with results from more expensive European Testers.
