Core Drill To Take Sample Asphalt

Core Drill To Take Sample Asphalt

 

Core Drill is a tool that can drill a concrete, reinforced concrete or asphalt. Core drill using a drill bit that is commonly called the Diamond drill bit. The size of the drill bit or a diamond drill bits are also varied, ranging from 1 "s / d 8". Power consumption of core drill machines are also no 1350W s / d 3000w subject of the drill core.
 

Sample obtained from a test Core Drill (called Corring) is cylindrical. From the sample, we can know precisely the composition of the structure of a road construction, pavement type, thickness, composition, ownership structure, and to examine the changes of the structure. The sample will then be taken to the laboratory for check lists, for example, by Marshall. Data will be obtained eg Stability, Bulk Density, Flow, Marshall Quotient. Then, with the data, there will be a reference for the design and compared with the design made ​​by the consultant.

 
Necessary tools
Necessary tools in this test is a machine Core Drill, water hoses and pumps, gas canisters.
implementation

     Put the machine Core Drill on the pavement to be tested in an upright position on a flat surface.
     Prepare water using a pump system. Keep in mind, the water is very useful in this work, because if it's too late to drill water will cause damage to the tool's Core Drill.
     Water hose is inserted into a small hole on the Core Drill, so the water can be drained by pumping. Thus the tool is not broken, especially drill.  

Turn on the machine Core Drill
     After ignition, turn the handlebar is at the top in Core Drill, to lower the drill slowly to drill the pavement at the point considered.

     After the pavement was drilled at a certain depth, turn the handlebars in the opposite direction to raise the drill
     Then take the results of drilling, using tongs. But the practice field yesterday, they use a flathead screwdriver to take the sample. That is probing the edges of the sample.

     After the sample is taken, and then measure the dimensions and thickness. Will be seen later in the individual layers of the pavement every few centimeters.
     Then the sample was taken for testing.
