TABLE 4 : ROCKWELL AND MOHR HARDNESS OF THE LIMESTONE SAMPLES
The compressive strength of 207.5, 204.6 and 203.4 MPa; and tensile strength of 13.86, 13.68 and 13.60 MPa were obtained for A, B and C respectively. Rockwell hardness values obtained are 89.0, 89The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.Los Angeles Abrasion Pavement Interactive

Limestone Types, Properties, Composition, Formation, Uses
Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations.performance of the limestone and dolomite aggregate. To support the claim, the aggregate suppliers Durability Index : T 210 D 3744 Abrasion (wet) As indicated in the table, the AHTD currently specifies the Los Angeles (L.A.)

Dolostone (Dolomite) : Properties, Formation, Occurrence, Uses
Limestone: Limestone can consist of various crystal forms of calcium carbonate, including calcite (rhombic crystals) and aragonite (orthorhombic crystals). Hardness: Dolomite: Dolomite has a hardness of around 3.5 to 4 on the Mohs scale. Limestone: Limestone’s hardness can vary, but it generally falls within the range of 3 to 4 The Schmidt hammer test is a non-destructive method which can be used in both laboratory and field to provide a quick and relatively inexpensive measure of rock hardness. The study investigated the relationship between the Schmidt hardness and modulus of elasticity, uniaxial compressive strength and index properties of nine types of Predicting uniaxial compressive strength, modulus of

Thermal conductivity of Limestone is 1.3 W/ (mK). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction.Limestone Density, Heat Capacity, Thermal Conductivity
