Asphalt Core Testing :: Eosso Brothers Paving

Core testing is an extremely precise tool Eosso Brothers Paving utilizes to determine what method of pavement repair is needed. We take a sample of the pavement core directly, allowing us to see exactly what is going on with the subgrade layers of your pavement and identify potential problems before they occur. This also allows us to test the ...



Test Method T632 - Transport for NSW

NOTE: Asphalt and foamed bitumen stabilised core trimming is not required for this method. See relevant asphalt or foamed bitumen material test methods for trimming requirements. (a) For concrete cores, follow the trimming procedure in AS 1012.14. (b) For road construction materials blended with cementitious materials and/or bituminous binders to


Asphalt & Concrete Coring - Earth Engineering Incorporated

Asphalt and concrete coring is a process where representative samples from an existing pavement, slab or structure is extracted for analysis. The coring is conducted with a diamond tip core-barrel mounted to an electric drill. Typically, the extracted core measure 4 or 6 inches in diameter. During the coring process, some water is sprayed into ...


Core Drilling of Hot Mix Asphalt (HMA) for Specimens of 4" or ...

The core drilling apparatus shall be equipped with a water spindle to allow water to be introduced inside of the drill stem while operating. 2.4. The cutting edge of the core drill bit shall be of hardened steel or other suitable material with embedded diamond chips in the cutting surface. The core barrel


DESIGN AND CONSTRUCTION GUIDELINES FOR FULL DEPTH RECLAMATION ...

The Department will take and analyze 6 in. diameter core samples and provide the following information in the contract documents: • Core Report which will include the location and depth of the existing asphalt in each core taken. • Existing asphalt pavement core gradations.


Asphalt Tests – Pavement Interactive

Asphalt Mixture Performance Test. Overview The asphalt mixture performance tester (AMPT) is the companion performance test for use with the Superpave mix design...



Concrete and Asphalt Core Drilling: When, Why, and How

Asphalt pavement presents unique problems when extracting core samples. It is softer than concrete but also more abrasive. The heat from the friction of diamond coring bits makes the bitumen softer and more viscous. As the material softens, it can pinch the diamond bit, stalling the drill and damaging the sample.


Asphalt and bitumen - testing for performance | World Highways

The stresses placed on modern asphalt and bitumen means that specialist equipment is essential to make sure performance specifications are met. As road traffic increases at a rapid pace and road safety becomes a priority issue, asphalt is put under increasingly higher stresses. For example, road surfaces are subject to compression, flexural tensions and tangential stresses: internal friction ...


ASTM D2726 and ASTM D3549 - How to Find the Bulk Specific ...

Asphalt Core Testing ASTM. These two tests cover the process of getting the bulk-specific gravity, density, and thickness of compacted asphalt core sections. The results of these tests will be used to find the unit weight of each compacted asphalt mixture, and can also be used with ASTM D3203 to determine the percent of air voids in an asphalt ...


Core Cutting in Asphalt Road | Lab Report for Core Cutting

Core cutting is traditional method of quality control. In this method, the surface of road, either Asphalt or Premix or DBM is chopped with the help of rotary driller. The driller consists of cylindrical drill bit of 15 cm diameter. Drilling is held to the depth greater than overlay thickness. A cylindrical bituminous cake is drawn out with the ...



Asphalt Testing Equipment - Gilson Co. - GlobalGilson.com

Gilson's asphalt testing equipment meets ASTM and AASHTO test standards for Marshall and Superpave mix design, binder, and pavement quality. Asphaltic concrete, or just asphalt, is the most widely used construction material for paving roadways. Demands on roadways from increased traffic volumes and axle loads are high and steadily increasing.


The Many Purposes of Taking Core Samples in Roofing

The inspector observes and documents the composition of the roof membrane, cover board, insulation, vapor/air retarder, thermal barrier and roof deck layers, thicknesses, and method of attachment for each layer. With multi-ply bitumen roof systems, the type of bitumen and number of plies can often be determined through core sampling.


Asphalt Testing Equipment | ELE International

The Marshall method tests for stability and flow of hot mix asphalt and produces sample densities close to those of field cores. ELE offers a selection of Marshall load frames, some of which can also be used for soil testing. Specific gravity is measured by the Rice Test and kits are available for the Percentage Refusal Density test.
