Bitumen
The earliest estimated use of bitumen dates back 40,000 years to the paleolithic age in which Bitumen was used to adhere handles onto primitive stone tools The use of natural bitumen for waterproofing, and as an adhesive dates at least to the fifth millennium BC, with a crop storage basket discovered in Mehrgarh, of the Indus Valley civilization, lined with it By the 3rd millennium BC refined rock asphalt was in use in the region, and was usBituminous materials are one of the oldest and most widely used construction materials While their components are obtained from finite resources, these Sustainability of bituminous materials ScienceDirect
Grindstone
A grindstone, also known as grinding stone, is a sharpening stone used for grinding or sharpening ferrous tools, used since ancient times Tools are sharpened by the stone's abrasive qualities that remove material from the tool through friction in order to create a fine edge Similar to sandpaper, each stone has a different grit that will result in sharper or duller tools In Australia, Aboriginal peoplesBitumen, dense, highly viscous, petroleumbased hydrocarbon that is found in deposits such as oil sands and pitch lakes (natural bitumen) or is obtained as a residue of the Bitumen Oil Sands, Extraction & Refining Britannica
The Archaeology and History of Bitumen ThoughtCo
In ancient times, bitumen was used for a huge number of things: as a sealant or adhesive, as building mortar, as incense, and as decorative pigment and texture on pots, buildings or human skinBitumen has more than 250 known applications, most of them used in paving and roofing applications: “(a) 85% of all the bitumen is estimated to be used as Bituminous Materials SpringerLink
Review of the uses and modeling of bitumen from ancient to
We start with a discussion of the various definitions for asphalt and bitumen and discuss briefly some of the many fascinating uses to which they have been put from Bitumen uses although the manufactured bitumen are of high quality today But the basics of their uses are as in the past and essentially like sealing, adhesion and protective coatings Today, Bitumen uses are more than Bitumen Uses in different industries like Asphalt and
Fact sheet: Aboriginal grinding stones First Peoples
Leaves and bark were crushed on grinding stones to make medicines Aboriginal people also used small grinding stones to crush soft rocks and clays (such as ochre) to make pigments The pigments were used to decorate bodies for ceremonies, to paint rock art, and to decorate objects such as possum skin cloaks and weaponsBitumen has a number of applications but it is mainly used either directly or indirectly in the construction and maintenance of roads It is estimated that 90% of its applications is in the road construction and maintenance industry Typical bitumen types for road applications includes paving grades,cutback bitumen, and bitumen emulsions Types of Bitumen and its Applications Bitumen Malaysia

Bituminous Materials: Learn Composition, Importance, Properties
Bitumen is a hydrocarbon product of natural or pyrogenous origin Typically, bituminous materials are made of graded aggregates and bitumen There is a small quantity of air as well in the bituminous materials, which makes it a threephase material Bituminous materials are typically composed of 80 to 87% of bitumen by weightWaterproofing: Bitumen 60/70 is also used for waterproofing applications, such as sealing foundations, basements, and tunnels It forms a strong barrier against water penetration PavementBitumen 60/70 uses LinkedIn
Bituminous Binders and Mixtures SpringerLink
Waterproofing systems and bituminous mixtures are the main materials regarding the use of bitumen and bituminous binders for main civil engineering purposes In the case of bituminous mixtures, the composition, properties and main products and applications are presented in the perspective of their use in pavement layersThe term bituminous materials commonly include all materials constituted by aggregate bound with either bitumen or tar, the latter term being used as a binder material before the era of bitumen Bituminous materials are used almost exclusively in road construction ( Fig 141) although bitumen meets industrial applications and other forms Bituminous Materials SpringerLink
