Book excerpt: Need for a means to control pavement denseness for bituminous concrete construction in Ohio was indicated several years ago by failure of some late season paving. The paving that failed carried up to 20 per cent voids into the winter. Such paving was easy prey to freezing and thawing, and stripping. The proportion of paving that failed to the total paving was small for any one construction season, although one single course resurfacing was almost entirely lost. While it is most important to correct conditions causing critical void contents, consideration must first be given to the accurate measurement of void contents. Several methods are available for the measurement of paving density. Perhaps the most widely recognized is the ASTM method for the determination of specific gravity of compressed bituminous mixtures (D 1188). Data presented in this paper compare specific gravities of cores obtained by the ASTM method, modified by dipping cores in paraffin and time- of-dry weighing, with specific gravities of the same cores obtained by three other methods. Methods are also available to determine the specific gravity of bituminous coated aggregates. For aggregates nonabsorptive to both bituminous material and water, any of the specific gravities shown in ASTM methods of determining specific gravity of coarse and fine aggregates (C 127 and C 128) can be used to determine accurate theoretical maximum densities. For aggregates with bituminous material absorption equal to water absorption, bulk specific gravity from the above methods can be used to determine accurate theoretical maximum densities. A method was presented in 1942 by Nevitt and Krchma (1) to estimate the absorption of bituminous material for aggregates by their absorptions of kerosine. The same year Goshorn and Williams (2) presented a method for the direct measurement of the amount of bituminous material absorbed by aggregate immersed in bitumen. Each of these methods was most useful for voids computations when the method accurately indicated the amount of bituminous material absorption that occurred in aggregates as they were coated in the mix.

This book was released on 1957 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laboratory of the National Crushed Stone Assn. has long been concerned with the specific gravity of aggregates for bituminous mixtures. About ten years ago, a limited study was undertaken in which four samples of coarse aggregate were coated with asphalt by dipping. The results indicated that the aggregates absorbed some asphalt, but the asphalt absorption was less than water absorption. Therefore, neither the bulk nor the apparent specific gravity values of the aggregate were applicable for computing the theoretical maximum density of a bituminous mix. In 1951, experiments were begun with the direct measurement of voids in compacted specimens by use of an air meter such as is used for measuring entrained air in concrete (1). While the equipment used was not particularly suited for this application, the results were encouraging. Still we were not completely satisfied with this procedure because there was always some doubt that all of the voids were being measured. The vacuum saturation procedure was first used in connection with the air meter tests on compacted specimens. This test was performed with the air meter chamber filled with water; thus, there was a possibility that the test specimen was absorbing some water while the equipment was being prepared. In order to minimize this source of error, specimens were initially saturated with water after evacuation of air. With porous mixtures it was found that this procedure filled practically all of the measurable voids.

Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: The broad gap between research on asphaltic concrete specimens prepared in laboratory bench-type equipment and test roads or public highways has been narrowed by providing full-scale paving equipment in a research facility. This facility permits asphaltic concrete pavement construction under conditions of control which cannot be reached in field operations. Paper 2: Laboratory and field data have been collected from 12 regular contract hot-mix asphaltic concrete paving projects in various areas of Texas for the purpose of comparing laboratory and field densities. Paper 3 proposes a mechanism by which mixes can be unstable at high temperatures during rolling and still be quite stable by normal design criteria.
