Book excerpt: A program of construction and the performance evaluation of three major Virginia experimental flexible pavements is reported. The objective of the program was to evaluate the performance of pavements incorporating new or timely design concepts and to assess the feasibility of these concepts for further use. Among the major findings of the study are: 1. A resilient select borrow material used over a resilient subgrade does not enhance pavement performance. When used between a cement stabilized subgrade and a crushed stone base, the resilient select material may, in fact, impair performance. There is some evidence that resiliency is reduced after a substantial number of wheel loads, with an improvement in subsequent pavement performance. 2. Pavements having cement treated crushed stone under a thin (3 in.) bituminous structure have performed very poorly. 3. Transverse shrinkage cracks reflect from a cement treated stone subbase through 3 inches of bituminous concrete in as little as 18 months, and through 7 inches in less than 5 years. 4. Where cement stabilized stone subbases are used and when truck traffic is normally channeled into the outer lanes, advantage may be taken of the omission of the stabilization from stone subbases under inner or passing lanes. 5. Shrinkage cracking aside, 4 inches of cement treated aggregate base, 4 inches of bituminous concrete, and 6 inches of untreated crushed stone base (all underlying 7 inches of bituminous concrete) give approximately equal performance after 5 years under heavy traffic conditions. Higher deflections and greater cracking on the pavement incorporating the untreated stone suggest that the performance may not be equal after many load applications.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook lays out the state of the art for modeling of asphalt concrete as the major structural component of flexible pavements. The text adopts a pedagogy in which a scientific approach, based on materials science and continuum mechanics, predicts the performance of any configuration of flexible roadways subjected to cyclic loadings. The authors incorporate state-of the-art computational mechanics to predict the evolution of material properties, stresses and strains, and roadway deterioration. Designed specifically for both students and practitioners, the book presents fundamentally complex concepts in a clear and concise way that aids the roadway design community to assimilate the tools for designing sustainable roadways using both traditional and innovative technologies.

Book excerpt: The instrumentation data of the multiple-wheel heavy gear load (MWHGL) tests were reduced and analyzed. By incorporating the performance of test pavements under traffic, relations between load and pavement response were established. A method was developed to compute the measured stresses and deflections of the test pavements; based on the method, the stresses and deflections can be computed for similar types of airfield pavements under different loads. Correlations were established between computed parameters and traffic performance data from the MWHGL test section as well as from many other pavement tests conducted by the Corps of Engineers. Based on the instrumentation data, the principle of superposition was found to be valid for flexible pavements. Attempts were made to reevaluate the equivalent single-wheel loads for MWHGLs by many different methods. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Deflection tests conducted during the construction and shortly after the completion of a large experimental pavement project are reported. Four different pavement designs, as follows, are compared: 1. 6-inch cement stabilized subgrade, 6-inch crushed stone base, 71/2-inch bituminous concrete. 2. 6-inch cement stabilized subgrade, 91/2-inch bituminous concrete. 3. 4-inch cement stabilized crushed stone subbase, 6-inch crushed stone base, 7 1/2-inch bituminous concrete. 4. 6-inch cement stabilized subgrade, 4-inch cement stabilized crushed stone base, 5 1/2-inch bituminous concrete. The results of these early tests support the following conclusions. 1. Pavements having equivalent design parameters are not necessarily equivalent in either early structural strength or in construction costs. 2. Very early deflection tests are not good indicators of the ultimate strength characteristics of pavements having cement stabilized layers. 3. Highly resilient soils must be stabilized to achieve a good working platform and to assure the early development of design strength. 4. Design No. 4, above, develops the design structural strength more rapidly and at a lower cost than the other three designs.
