It should be noticed that both porous asphalt and pervious concrete blocks are not economically affordable in many developing countries. Therefore, this proposal, for the first time, introduces a new pavement called Travertine, a mineral and natural pavement, which is classified as a porous pavement and can naturally infiltrate runoff thorough its voids. Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In this study, Travertine has been under experimental studies for evaluating its ability to control the quality and quantity of storm water runoff. The collected data has been compared to porous asphalt and concrete blocks as most famous and useful types of pervious pavements.
Groundwater environments

Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls and around hot or cold springs. Calcium carbonate is deposited where evaporation of the water leaves a solution that is supersaturated with chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls. The groundwater draining from a limestone aquifer is saturated with CaCO3 within the system. As it emerges and the partial pressure of CO2 drops, calcite will precipitate. This gives rise to terraces formed from travertine. The limestone mountains in southern Mexico provide spectacular examples (Figures 1.44 and 1.45).

Travertine, stalactite and calc-sinter are made of chemically deposited calcium carbonate from saturated solutions. Calc-sinter (or tufa) is a deposit formed around a calcareous spring. Stalagmites and stalactites are columnar deposits built by dripping water in caverns and on the joint planes of rocks (see Chapter 2). Travertine is a variety of calc-sinter, cream or buff-coloured, with a cellular texture due to deposition from springs as a coating to vegetable matter. When the latter decays it leaves irregular cavities. There are deposits of travertine in Italy, in the Auvergne, and elsewhere. The important deposit on the banks of the R. Anio near Tivoli is about 140 m thick, and is soft when quarried but hardens rapidly on exposure. Travertine has been used in many buildings for interior or exterior panelling; with or without a filler; and in slabs for non-slip flooring.
Performance assessment of travertine waste as alternative concrete aggregate
Published in European Journal of Environmental and Civil Engineering, 2022
Travertine, generally settled in hot mineral springs around the world, is a sedimentary rock, which is frequently used as a material for many purposes in constructions. Its differences from the other natural stones come from mainly its formation, hardness and appearance (Sarami & Mahdavian, 2015). Travertine is commonly chosen for inside and outside applications because of its beautiful appearance, resistance to environmental conditions and versatility. This natural stone has been an essential construction material for memorial buildings and civil structures from ancient times to present. One of well-known ancient monument (the Colosseum) made primarily of travertine was constructed in 70 AD. Also, travertine is commonly seen in ornamental elements like sculptures, facade, flooring and wall cladding beside used as structural element (Demirdag, 2013; Urosevic et al., 2010). In addition, it can be used in production of brick, curbs, keystone and various materials as an alternative building material (Cobanoglu et al., 2014). Additionally, travertine is used in different aspect in civil constructions, such as in previous pavement to control urban-flooding (Rahimi et al., 2018).

The external travertine cladding of the BdN palace coats two-thirds of the building and is partially integrated into the masonry structures. In fact, the travertine is here used in ashlar blocks laid into patterns of mortar to compose polygonal wythes or piled up in round blocks to shape columns. Non-loadbearing elements are cut in thin slabs of travertine, ashlar dressed and used for decorative purposes. Slabs of green, red, and white marble are also used as an indoor coating (Ciucci, Lux and Purini 2015; Pisani 2012). Marble is positioned all over the place spanning from floors to ceiling to figure the Piacentini’s idea of architecture.
