The specific peculiarity and historical significance of the region is the interconnection of the sandstone subsoil with the local economy, culture, and art. It is not only the use of natural resources in the stone industry (for example, the export of sandstone treated or its use in local construction, as reflected, for example, in the sandstone basement of older houses) but in its artistic processing. In the region itself and its immediate vicinity, at least five major real estate (sandstone) cultural monuments can be found. The first one is the Baroque Hospital Kuks (beginning of the 18th century), with sculptures of the most significant sculptor of the Czech Baroque—Matyáš Bernard Braun (1684–1738). Another is the Baroque Walenstein lodge in Jičín (17th century), the reservoir with sandstone dam Les Království (technical monument and one of the oldest Czech dams from the beginning of the 20th century), and in Hořice the monumental Neo-Renaissance cemetery portal (beginning of the 19th century) and the Neo-Gothic Town Hall (end of the 19th century).

The answer to this question is not so difficult, if we look that the dimension stone quarry that use some kind of cutting procedure with wires as the helycoidal wire for softer rocks as the carbonated rocks (limestone and marble) or also the new diamond wires to cut harder rocks as granite and quartzite’s from were the blocks for are prepared on the quarry site, for use in the dimension stone industry. This type of extraction has not so great noise levels, and the working conditions in a open cast dimension stone quarry is a better environment than a normal stone quarry.

Tennessee marble is limestone from Tennessee, North America. Tennessee stone has been quarried for the dimension stone industry and lime since the Colonial times in America. The quarrying of Tennessee can be worked out in relation to the construction of the Francis Alexander Ramsey home in Knox County, Tennessee, USA, in 1797. The stone is a popular dimension stone in USA and Canada and is being quarried for sculptural purposes as well (Byerly and Knowles, 2017).

Global infrastructural demands have made the construction industry to contribute to 25% of global carbon emissions (Hong, Shen, Peng, Feng, & Mao, 2016). Concrete which is the most widely and ordinarily utilised construction material has 70% of its volume occupied by aggregates (Tiwari, Singh, & Nagar, 2016). This has triggered an exponential growth in demand of these natural resources (Farinha, De Brito, & Veiga, 2012). Demand coupled with depletion of river sand and coarse aggregates and the environmental concern associated with the mining activities, have driven the construction industry’s attention towards finding suitable alternatives. Industrial wastes have been proven to be viable substitutions to natural aggregates because when these materials left as such, occupy landfills and cause environmental degradation (Alyamaç & Aydin, 2015). Conversely, the concrete industry can be a major consumer of industrial wastes (Siddique, Shrivastava, & Chaudhary, 2017). Out of the many industrial wastes, wastes produced from marble dimension stone industry have been proved to be a lucrative alternative to natural aggregates.
Effect of filler on the bitumen-aggregate adhesion in asphalt mix

The objective of this study is to analyze the influence of the type of filler and their quantity on the active and passive adhesion between the bitumen and the aggregates in the asphalt mix. This study primarily addresses the performance of various waste fillers and conventional stone dust regarding active and passive adhesions, to ensure moisture resistant as well as economical asphalt mixes. In addition to that, the possibility of a relationship between active and passive adhesion is explored. To achieve these aforesaid objectives, asphalt concrete mixes were prepared utilising four different types of wastes along with conventional stone dust as fillers. The wastes utilised in this study are glass powder (GP) (glass industry), red mud (RM) (aluminium industry), Kota stone dust (KS) (dimension stone industry) and copper tailings (CT) (copper industry). These wastes were chosen due to their variable physical and chemical nature as well as due to their wide global production. KS and SD have a predominance of calcium-based minerals, whereas, CT and GP have a large amount of silica in their composition. RM, on the other hand, have predominance of iron and aluminium in its composition. This wide disparity amongst mineralogical composition can be suitable to assess the effect of filler composition on adhesions. These fillers were added at variable compositions (4, 5.5, 7 and 8.5% by weight of aggregates) in the asphalt mix. The analysis of active adhesion in between aggregate and bitumen is done using mixing time analysis. On the other hand, Texas boiling water test was chosen for the study of passive adhesion due to its simplicity and short testing time (Pasandín and Pérez 2015). All analyses were conducted on asphalt concrete mixes designed with dolomite aggregates (13.2 mm nominal maximum aggregate size) mixed in a specified gradation (Figure 1) with VG-30 bitumen used as a binder.

Among the various industrial wastes produced in India, the sandstone waste generated from the stone mining and grinding industry accounts for a large proportion, which ends up in landfills. India has enormous sandstone reserves, leading it to pioneer stone mining [14]. The Federation of Indian Granite and Stone Industry estimated that the Indian marble industry is worth $85 million and accounts for 27% of the total stone produced globally [15]. Among the different stone reserves, Rajasthan state located in the northern region of India is the biggest producer of sandstone with its approximate share of 90% out of the estimated 1000 million tones reserves of sandstone [16]. It is reported that, 25% waste is produced during mining and 25% waste generated during dressing, processing as well as polishing process of mined out sandstone ends up as total of 50% sandstone waste [17]. Unsafely dumped sandstone powder waste generated during cutting and finishing process is a very fine particulate matter causing numerous health problems to the nearby residents after long term exposure [18]. Airborne sandstone dust particles leads to silicosis and pneumoconiosis diseases which are associated with chronic bronchitis in the long term exposed residents [19]. To reduce the landfilling problem, various studies suggest using sandstone waste as a substitute for natural aggregates in the mortar and concrete structures. Kumar et al. [20, 21] reported the suitability of coarse aggregate replacement up to 40% with quartz sandstone in concrete showing excellent long term performance. Arif et al. [22] reported the use of sandstone slurry (15%) as a partial replacement of aggregates in concrete with compressive strength comparable to control and good resistance against sulfate attack. Cao et al. [23] reported the utilization of waste sandstone sand (sieve size < 150 µm) as a fine aggregates with improved compressive strength and alkali silica reaction in mortar. Rathor et al. [24] also reported the utilization of waste sandstone microfines (up to 25%) with particle size less than 75 µm as fine aggregates in concrete improved the mechanical and durability properties. Different studies also suggested the use of sandstone powder generated during the cutting and finishing process as a cement substitute. Basu et al. [25] reported the utilization of sandstone slurry (up to 15%) as a replacement of Portland pozzolana cement in self compacting concrete. The durability test results were reported to be comparable with that of the control concrete. In another study, dried sandstone slurry was used as replacement of cement up to 20% in self compacting concrete with promising results in mechanical strength, permeability and microstructure [26].
