There is an ASTM test for Penetration of Asphalt and so you should look to buy one for that test. Otherwise, there are numerous other penetrometers used for other things. The one you want also has a given weight of the needle apparatus. therefore, youmay hve to look for the word needle, rather than penetrometer. 字串4
You also need a water bath of constant temp for that test. I used to see it run, with the test sample sitting in the water.
