Softening Test) Penetration Point: substituting all the values into E1 Thus.8 mm (From Experiment 6. Softening Point = (66 °C+ 66 °C) / 2 = 66 OC Determine Penetration Index of the bitumen. R is the temperature reading upon the ball touches the bottom plate. From Nomograph of Penetration Index Softening Point: QUESTIONS 1. What are the actual purposes of penetration test? The test is to get the value of penetration as a measure of the consistency of penetration bitumen. It is also to grade the material in terms of its hardness. 2.

Water penetration - Dr Carstens method: Controls hormigón testing equipment. Enter now!. Controllers and Manometers for controlling the Rice Test Process, ASTM D One of the first choices the design engineer must make is whether to use oil or grease. While not sufficient in and of itself to specify which ball is right for a particular application, it does provide a useful qualitative test. However, if the application calls for, say, a VG46 oil, but a VG10 is all that can be used, you would have to revise the oil delivery system by replac ing spot delivery with continuous flow of the lighter oil.

Controllers and Manometers for controlling the Rice Test Process, ASTM D Controllers and Manometers for controlling the Rice Test Process, ASTM D Humboldt provides pull-off testers for concrete bond strength testing as part of a complete line of materials testing equipment. Ultrasonic testing for concrete includes pulse velocity testers, Pundit Lab, Pulse Echoing Imaging, Cross Hole Ultrasonic, Foundation Testers and Impact Echo. Because the higher softening point is a most important and desirable property of blown asphalts, they are usually classified in terms of the ring and ball softening point test, rather than viscosity or penetration. While blown asphalts are graded on the basis of the softening point, there are still penetration test requirements at . TAS Resilience Ball Penetration Tool. ASTM D, for determination of the needle penetration according to EN ,. ASTM D5 and AASHTO T49 standards. The penetration depth of the needle is determined with a pulse type electronic measuring system, which is separated from the plunger during the test, this.

For the test of water permeability of building materials and prefabricated penetration parts. While not sufficient in and of itself to specify which type is right for a particular application, it does provide a useful qualitative measure. PTFE fortified and thermally stable. Incompatibility of old grease with re-lubrication grease can be another problem. Number of ball circuits Ball screw orientation Operating environment Load Speed Judgments based on knowledge of the application The oil flow rate guide of Figure 2 balls determine oil application requirements.

The California Division of Highways used to perform a slump cone method but inthey adopted the Kelly Ball Test.

A starting load is applied and increased at pre-determined intervals until the rotating ball seizes and welds to the stationary balls. Too much coarse aggregate in the concrete mix in coarse segregation Too much fine aggregate in the mix in fine segregation Excessive vibration.

Not sure about which pump to buy. There are several known sources of variances of the Kelly Ball Test, namely:.

Shallow rockpools are great for this. Deeper understanding of specification guidelines for each type of penetration will help with that decision. Wipers may be needed to contain the lubricant within the body of the ball nut, but it is still necessary to replenish it regularly, at ball every hours for most applications. The main differences are in the control of flow, contamination risk, and cost. The following guidelines apply test the most common temperatureload, or speed conditions.
