Available in PDF, EPUB and Kindle. Book excerpt: The Iowa DOT has been using blended cements in ternary mixes since 1999. Use of these supplementary cementitious materials gives concrete with higher strengths and much lower permeability. Use of these materials has been incorporated for use in High Performance Concrete (HPC) decks to achieve lower permeability and thus long term performance. Since we have been using these materials in paving, it would be informative to determine what concrete pavement properties are enhanced as related to high performance concrete. The air void system was excellent at a spacing factor of 0.0047 in (0.120 mm). AVA spacing factor results are much higher than the hardened air void analysis. Although only 3 samples were tested between the image analysis air content and the RapidAir457, there is pretty good agreement between those test methods. Air void analysis indicates that excessive vibration was not required to place the concrete. Vibration was well within the specification limits with an average of 6683 vpm's with a standard deviation of 461. Overall ride of the project was very good. The average smoothness for the project was 2.1 in/mile (33.8 mm/km). The International Roughness Index (IRI) was 81 in/mi (1.29 m/km). The compressive strength was 6260 psi (43.2 MPa) at 28 days and 6830 (47.1 MPa) at 56 days. The modulus of rupture by third point loading (MOR-TPL) tested at 28 days was 660 psi (4.55 MPa). The AASHTO T277 rapid chloride permeability results at 28 days using the Virginia cure method correlate fairly well with the 56 and 90 day results with standard curing. The Virginia cure method 28 day results were 2475 coulombs and the standard cure 56 and 90 day test results were 2180 and 2118, respectively.

This book was released on 2011-10-12 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the early 1990s, curling and warping of Portland cement concrete pavement did not concern pavement engineers in many transportation agencies. Since beginning construction of the interstate system in the United States in the late 1950s through the late 1980s, the performance of Portland cement concrete pavement has been associated with properties of concrete as a pavement material. In those years developed standards and design guidelines emphasized better concrete materials and construction control. At the time, combining curling and loading stresses was quite controversial due to the nature of the load-carrying capacity of concrete pavement and the occurrence of types of loads. Arguments developed that the types of loads (traffic and curling) rarely occurred at the same time of day. The concrete pavement design principle did not include the effects of curling and warping of concrete pavement as determining design factors in pavement performance. This research project was initiated as a response from the INDOT Pavement Steering Committee related to the joint spacing of Jointed Plain Concrete Pavement in Indiana. There was an initiative in the Committee to reduce the joint spacing from 18 feet to 15 feet as a way to reduce premature concrete pavement deterioration. There was an indication that some newly paved JPCP had transverse cracks even before the pavement section was opened to traffic. In this experimental study, several important conclusions were drawn from temperature analysis, stress-strain analysis, and other data analysis. The analysis from this experimental study supports the decision by INDOT to shorten the concrete pavement joint spacing to increase the performance of Jointed Plain Concrete Pavement in Indiana.

This book was released on 2004 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the properties of three high performance concrete mixtures placed in a jointed plain concrete paving project on I-64 in Newport News, Virginia, to reduce the shrinkage and improve the flexural strength of the concrete. Two mixtures contained ground-granulated blast furnace slag with 2-inch and 1-inch nominal maximum size (NMS) aggregate, and the third mixture contained Class F fly ash with 1-inch NMS aggregate. Air-entrained paving concretes with satisfactory strength, low permeability, and dimensional stability were prepared using concretes with Class F fly ash or slag and 1-inch or 2-inch NMS aggregates. Slipform pavers satisfactorily placed these concretes. The test sections were in excellent condition after six winters based on a visual survey. Falling weight deflectometer data indicated a better load transfer with the larger aggregate size with everything else being equal. The study also evaluated the maturity method in the continuation of the project on I-64 in Hampton, Virginia. After the evaluation, the pavement was changed to continuously reinforced concrete and the concrete properties were tested in accordance with the recently introduced Guide for Mechanistic-Empirical Design of New and Rehabilitated Pavement Structures (known as the proposed AASHTO M-E Design Guide). In the Hampton portion, a Class F fly ash mixture with the 1-inch NMS aggregate was used. The use of large aggregate, provided the particle shape is acceptable, and uniform combined grading should be specified for concretes with reduced water and cement contents. The maturity method can be used to determine the pavement's readiness for opening to traffic and should be included in the specifications.

Available in PDF, EPUB and Kindle. Book excerpt: In the construction industry, high early age strength concrete is concrete that achieves a loading strength in a matter of hours to days. Due to the accelerated strength gain of high early age strength concrete it is expected to continue to gain strength after the the traffic load is introduced. The target of this investigation is high early age strength concrete for the purposes of road and bridge deck repairs.

Available in PDF, EPUB and Kindle. Book excerpt: Rigid pavements make up a significant percentage of highway systems in the United States and abroad. Concrete pavements provide an economical and durable solution for highway systems, because the pavements last longer and require less maintenance. Recently, there has been great interest in the construction of a higher quality concrete pavement, referred to as High Performance Concrete Pavements (HPCP), which could be in service longer and have lower maintenance and life cycle costs. General criteria were established by federal and state highway agencies to help in the design of these more durable and economical concrete pavements. This higher quality concrete pavement should incorporate recycled waste products, and utilize innovative construction equipment and procedures. These pavements should also have a shorter construction time and an ultra-smooth ride quality surface. With these criteria in mind, investigations have been launched to discover methods for improving the quality of concrete pavements. One area of interest involves the use of ground granulated blast furnace slag (GGBFS) as cementitious material in concrete pavement.

Book excerpt: This report documents enhancements incorporated in the (HIgh PERformance PAVing) HIPERPAV II software. Enhancements made within this project include the addition of two major modules: a module to predict the performance of jointed plain concrete pavement (JPCP) as affected by earlyage factors, and a module to predict the early-age behavior (first 72 hours) and early life (up to 1 year) of continuously reinforced concrete pavement (CRCP). Two additional Federal Highway Administration (FHWA) studies were also incorporated: one that predicts dowel bearing stresses as a function of environmental loading during the early age, and a module for optimization of concrete paving mixes as a function of 3-day strength, 28-day strength, and cost. Additional functionality to the software was also incorporated by reviewing and prioritizing the feedback provided by users of the first generation of the software, HIPERPAV I.

Available in PDF, EPUB and Kindle. Book excerpt: This research study, sponsored by the Federal Highway Administration, summarizes the field performance of eight high-early-strength (HES) concrete patches between 1994 and 1998. The patches were constructed under the Strategic Highway Research Program (SHRP) between June 1991 and July 1992 and were located in 5 States (Arkansas, Illinois, Nebraska, New York, and North Carolina) using existing State construction practices. The patches were constructed mainly with Type 111 cement, four different types of coarse aggregate, and three different types of fine aggregate. Similar types of air entraining admixtures, water reducers, and set accelerators were used at all except the North Carolina site. The patches were located in areas with varying environmental and traffic conditions. The performance criterion of interest was durability. Durability of he HES concrete was quantified over a period of 7 years using various indicators including compressive strength, static elastic modulus, rapid chloride permeability, and asphalt concrete (AC) impedance. The HES patches were also examined visually to locate any material- or durability-related distresses. This report discusses in detail the effects of climate and material properties on the HES concrete durability. Some of the results of interest include the effect of water reducer type, curing method, and aggregate type on long-term durability. The report also presents comparisons of the rapid chloride permeability and AC impedance test results and the rate of strength gain for the mixes evaluated. Overall, the HES patches performed well with no obvious signs of deterioration. However, the results were not conclusive because the performance monitoring period was relatively short. There is a need for further research in the areas of long-term HES concrete mechanical properties and durability.

Book Synopsis Concrete Pavement Design, Construction, and Performance by : Norbert Delatte
Download or read book Concrete Pavement Design, Construction, and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2007-09-12 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.
