    Table 1. Cheng, D. Kandhal, P. As the result, there has an urgent need to enhance the ability of asphalt concrete mixture to resist distresses happened in pavement. However, because of the cost and com- plexity of the new methods, the existing consensus properties may have applicability in field labs for some time to come. The study indicates the possibility of using waste concrete dust and brick dust as filler in bituminous mix.

    Marek, C. This variability may mask relationships with performance. Lynn, and R. The aggregates are generally divided into coarse, fine and filler fractions according to the size of the particles. Among the four fillers ceramic waste scores the highest softening point regardless the filler particle size.

    Sulfate Soundness Aggregates can deteriorate from wetting and drying or freezing and thawing cycles. At present the most commonly used method of detailed rheological testing of binders is by means of dynamic mechanical methods using oscillatory-type testing, generally conducted within the region of Linear Viscoelastic LVE response. Pine, and S. In fact, it is an active material whose activity occurs in the interface between the applied load and the asphalt binder [ 13 ]. The authors like to thank all staff members in various laboratories for their help and support during preparation of samples and testing. Early work indicated that both the size of the filler and the asphalt binder com- position had an impact on the stiffening effect.

Wilson, J. Al-Jacob, and S. Trautvain, Evgeniy A. If agencies excessively favor to some certain kinds of excellent aggregates, the cost of construction could be considerably expensive. In terms of filler type, the penetration, softening point and viscosity of mastics containing ceramic waste were found to be superior to those containing other types of fillers.

Stuart, K. The production, storage, transport, and laying of asphalt mixtures cause compositional changes, i. The aggre- gate bulk specific gravity is required to calculate VMA, and the aggregate fines content is required to calculate dust-to-asphalt proportion.

This was evidenced by the good historical perfor- mance of many agency-used mixes that passed through the restricted zone by specifica- tion prior to the adoption of the Superpave method.

Estimation of Appropriate Filler Quantity in Asphalt Mix from Microscopic Studies

Model Material and Con- struction Guidelines. Instead, the aggregate gradations and physical properties included in the Superpave mix design method were developed through the use of a modified Delphi approach 1. Finally, HMA is just one use for aggregate.

A major objective of the asphalt research program was to identify and validate engineering properties that could be directly linked to the performance the response to traffic loading and environment of asphalt binders.

The period of aging in wet stockpiles should be established by process-control testing to satisfy deleterious components criteria autoclave soundness, ASTM D 12 expansion testing.

Masad, and B. Rutting Resistance: The high Effects of aggregates and mineral fillers on asphalt mixture performance book 1. These tests are employed in concert to ascertain that the aggregate used in the production of HMA will be durable. Frictional Properties: Experience in several countries with steel slag aggregates in hot mix asphalt suggests that very satisfactory frictional resistance can be anticipated.

Thermal Properties: Steel slag aggregates have been reported to retain heat considerably longer than conventional natural aggregates. The quality of mineral aggregates for road-paving materials has generally been specified by the toughness, soundness durabilitycleanliness, particle shape, angularity, surface texture, and absorption.

Hand, A. If the particle size of the gravel feed stock is not large enough to allow significant particle size reduction in the production of the final product size say, one-third or one-quarter of the feed sizethen it is impossible to consistently produce very high levels of fractured faces.

Deleterious materials are organics or other unsuitable materials such as coal and lignite. Personal communication with John Hinrichson, In addition, the predicted permanent deformation performance of the twelve mastics was greatly above the conventional penetration grade asphalt binder.

Oil storage wastes, called oil sludges, are proposed to use as a surfactant. Decrease in water saturation index is detected in asphaltic concrete with activated mineral powders unlike in the test specimen.

Its use requires proper selection, processing, aging, and testing to ensure that it will perform in accordance with intended design specifications.

The mastic was continuously stirred as it cooled to prevent settling. This assessment resulted in the following recommended tests and performance specifications for slag aggregates: 13 Petrographic examination should be undertaken of all steel slag aggregate to identify the presence of deleterious components.
