This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warm Mix Asphalt (WMA) technology has the capability of lowering the temperature at which the asphalt is mixed and compacted by 30°C or more without compromising the performance of asphalt pavement. The reduced difference between asphalt mix and ambient temperature results in a lower cooling rate thus allows for long haul, sufficient compaction time and late season projects compared to the conventional Hot Mix Asphalt (HMA). In northern climate, asphalt paving season is relatively short and paving is often done late in the season when weather conditions are less than ideal. The potential benefit of WMA, among others, is an extended paving season for the City of Winnipeg. Reduction in production temperature also comes with other positive impacts both economically and environmentally. The objective of this study is to evaluate the installation of WMA, compile experiences with this technology and evaluate their effects on construction methods and performance. The study further attempts to evaluate the effectiveness of the WMA chemical additives and its dosage rate as liquid anti-strip agents on the properties of WMA mixtures through field and laboratory testing programs. In addition to the overall effectiveness of WMA, the study aimed to evaluate its economic cost relative to Hot Mix Asphalt (HMA). A chemical additive was used at three different dosages (0.3, 0.5 and 0.7 percent by weight of asphalt cement). The additive has the ability to improve mixing, aggregate coating, workability, compaction and adhesion with no change in materials or job mix formula required. The study showed that WMA could be successfully placed using conventional HMA paving practices and procedures. Among the different additive dosages used, 0.5% had a better overall performance. The moisture sensitivity tests indicated the highest Tensile Strength Ratio (TSR) at this dosage, suggesting the lowest moisture damage susceptibility. All four mixtures had low rutting resistance potential with no significant difference among them. The WMA showed a higher cracking resistance compared to HMA. The WMA price was between 2% to 11% higher than conventional HMA including the costs of additional testing as well as the WMA additives.

Download or read book Comprehensive Performance Evaluation of In-place Recycled Hot Mix Asphalt as Unbound Granular Material written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A promising pavement rehabilitation strategy that is of interest to state highway agencies and local governments involves the in-place pulverization of failed hot mix asphalt (HMA) pavements and re-use of the pulverized material as a granular base material. Advantages of this technique include a reduction in the use of virgin aggregate, a reduction in the amount of construction traffic, and removal of the potential for reflective cracking from the existing cracked pavement layers through the new HMA surface. However, the performance of this technique has not been comprehensively evaluated, and, in particular, permanent deformation characteristics. In this thesis, four pilot projects in northeastern California were used to evaluate the pulverized material and this rehabilitation strategy. The characteristics and performance of the pulverized material were evaluated by comprehensive laboratory and field testing, and analyses. Based on the multistage repeated load triaxial test results, the shakedown limits of the pulverized material were estimated and compared with the stress states calculated from the cross-anisotropic finite element analyses based on real traffic and climate data. A recursive-incremental damage model was used to predict permanent deformation of the pulverized base layer over the long term and to compare it with that of typical aggregate base material. Based on the comprehensive laboratory testing, field testing, and analyses, the pulverized material was found to be generally stiffer than typical aggregate base material, possibly due to better aggregate shape than that found in typical aggregate base material. The pulverized mateiral has less permanent deformation resistance at low stress levels but greater resistance at higher stress levels than typical granular material used in California. Possible reasons for the lower permanent deformation resistance at low stress levels might be the laboratory compaction method and that the recycled HMA in the pulverized material undergoes additional breakdown under initial loading since coarse fractions of the pulverized materials are greater than that of the comparison virgin aggregate base. Overall, the performance benefits of this rehabilitation strategy make it a viable option for flexible pavement rehabilitation.

Download or read book Evaluation of Jointed Reinforced Concrete Pavement Rehabilitation on I-64 in the Richmond and Hampton Roads Districts of Virginia written by Brian K. Diefenderfer and published by . This book was released on 2009 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning in 2004, the Virginia Department of Transportation (VDOT) undertook a series of pavement rehabilitation projects to address deficiencies in three sections of the I-64 corridor between Richmond and Newport News. I-64 serves as the primary avenue between the Richmond and Hampton Roads metropolitan areas and carries a combined traffic volume ranging from approximately 20,000 to 90,000 vehicles per day. For nearly 100 mi, this roadway is a four-lane divided facility that was originally built between the late 1960s and early 1970s as either a jointed reinforced or continuously reinforced concrete pavement. The existing concrete pavement was rehabilitated using three rehabilitation procedures: two standard approaches and an experimental approach. The standard rehabilitation procedures included the use of full-depth portland cement concrete (PCC) patches overlaid by a hot-mix asphalt (HMA) overlay and full-depth PCC patches followed by grinding of the pavement surface. The experimental rehabilitation procedure consisted of the use of full- and partial-depth HMA patches followed by an HMA overlay. The purpose of this study was to document the initial condition and performance to date of the I-64 project and to summarize similar work performed by state departments of transportation other than VDOT. The pavement rehabilitation cost per lane-mile was nearly 20% less for the section of I-64 for which full-depth PCC patches followed by grinding of the pavement surface was used than for the other two sections. However, the experimental results do not allow for a comparison to determine any differences in the structural capacity or service life between the sections. The study recommends that VDOT's Materials Division annually monitor the ride quality of the pavement in the three rehabilitated sections of I-64 so that the end of service life can be defined as the pavement roughness increases because of deterioration. Further, the Virginia Transportation Research Council should collaborate with other research organizations to encourage and pursue full-scale or laboratory-scale accelerated pavement testing to determine the optimum repair materials and methods for pre-overlay repair of existing PCC pavements and to develop models to quantify the deterioration of an asphalt overlay placed over an existing concrete pavement because of reflection cracking.
