Asphalt concrete is a viscoelastic multiphase porous material consisting of asphalt, aggregates and mineral filler. The composite has good flexibility, durability and impervious properties, usually as an impervious body of hydraulic structures. Technology characteristics of the asphalt concrete impervious panel is summarized and the key of the structure design is reviewed according to the specification. Combining with engineering practice, research results provide a useful reference for the technology development and application of asphalt concrete impervious panel.

Introduction. Currently, the problem of disposal and recycling of industrial waste is extremely relevant. The article analyzes the economically feasible and environmentally friendly ways of the processing or using waste generated during the production of the asphalt concrete component — enriched mineral filler. Problem Statement. The aim of the study was to find the most economically feasible and environmentally friendly ways to process or use waste generated during the production of enriched mineral filler at one of the enterprises of the Rostov region. Theoretical Part. The paper considers the composition of the enriched mineral filler as the main product of production and a source of by-products, the technological process of its manufacture, as well as the composition of the resulting by-products to be disposed. Based on the results of these studies, the assessment of probable ways of waste disposal was performed and the optimal method of recycling was selected. Conclusion. The choice of the most appropriate method of waste disposal from the production of mineral filler allows you to reduce the total amount of waste at the enterprise and significantly reduce the negative impact of the enterprise on the environment. To implement the proposed technology of mineral waste disposal, the relevant technical conditions and regulations are being developed.

Mineral filler is the finest fraction of aggregate (smaller than 75 gm) used in the production of asphalt paving mixed. It is essential for producing a mixture that is dense, cohesive, durable, and resistant to water penetration. In spite of the fact that filler is very small proportion of the total aggregates in the mix, due to its rather high affinity for asphalt, the changes in the type of the filler can cause the paving mixture to perform satisfactorily during the design life or deteriorate rapidly under the effect of traffic and environmental impact. The objective of this study is to investigate the effect of mineral filler types (three types, limestone dust, Portland cement and hydrated lime) in the durability of asphalt concrete mixture. To achieve the objective of this study, Marshall mix design method was utilized to produce asphalt concrete mixes at their optimum asphalt content. The mixes were, then, tested to investigate their durability properties including moisture damage and fatigue characteristics. The results indicated that the mixes prepared with hydrated lime have superior resistance to moisture damage in comparison with Portland cement and lime stone dust. On the other hand, the mixes prepared with Portland cement type of filler showed better resistance to the fatigue failure of asphalt concrete pavement.

The paper aimed at assessing the feasibility of using natural zeolites as a mineral filler substitute for asphalt mixtures produced at around 120 °C temperatures with a water foamed binder and compacted at 100 °C. The tests utilized the AC 16 asphalt concrete mixture intended for the binder and base course with the mineral filler fraction amounting to 4% by wt. comprising limestone dust and zeolites (when added). A reference hot mix and warm mix with foamed bitumen were compared to two mixes with zeolites, with one containing 0.4% of a water-modified (20% moisture content) zeolite and the second containing 1.0% of natural air-dried zeolite. The investigations included: assessment of campactability using a gyratory compactor, air void content, indirect tensile strength before and after conditioning with one freeze-thaw cycle, and the resulting resistance to moisture and frost damage. The mixtures with zeolites exhibited decreased compactability when compared to reference mixes, which the Marshall samples confirmed. The mechanical properties have also deteriorated in zeolite-bearing mixtures, which was partially accounted to the decreased compaction level. It was concluded that the temperature of the mixture production was too low for the zeolite water to significantly improve the compactablity of the asphalt mixture and its mechanical parameters.

This study was conducted to access the performance of asphalt concrete produced with coal bottom ash as partial replacement of cement in the mineral filler. The Marshal Mix design method of hot mix asphalt (HMA) samples preparation and testing was adopted. Fifteen (15) samples of HMA compacted and used for volumetric and stability testing at a varying percentage of bitumen contents (5.0, 5.5, 6.0, 6.5, and 7.0%,) following the Asphalt Institute and Nigeria General Specification for Road and Bridges (NGSRB) approach for determining optimum bitumen content (OBC). An Optimum bitumen content of 5.5 % was obtained and used throughout the study. Another set of 15 samples of the HMA were prepared and compacted at varying percentage replacement of cement with CBA in the order of 15, 20, 25, 30, and 35% by volume of cement to determine the optimum dosage of the coal bottom ash that will satisfy the requirements for the strength and durability of wearing course of flexible pavement. The Marshall Stability, flow, and the volumetric properties test results obtained indicated that the samples prepared with 25% CBA as filler with OBC of 5.5% satisfied the requirements of the NGSRB for wearing course of flexible pavement. Hence, the addition of up to 25% CBA by volume of cement in asphalt concrete can reduce the consumption of cement and provide a proper means of CBA disposal.Keywords- Coal Bottom Ash (CBA), Marshal Stability, Marshal Flow, Mineral filler, Optimum Bitumen Content (OBC)
