Place the specimen in the boiling distilled water and stir with a glass rod at the rate of one revolution per second for 3 minutes. The aggregate shall retain a mini mum of 90% of its asphalt film compared with the remainder of the sample, upon completion of this procedure. 260 2 . Test 2 . Approximately 500 g of produced mixture shall be heated to 250°F in a laboratory oven for 2 h, stirred, and cooled to 200°F. A portion of the mix shall then be placed in boiling 902.02

The aggregate shall retain a minimum of 90% of its asphalt film compared with the remainder of the sample, upon completion of this procedure. 270 Note: The purpose of these tests is to determine the relative compatibility of the aggregate and asphalt, and to detect tendency of Asphalt Emulsions to re-emulsify. If Test 1 returns unsatisfactory results, Test 2 may be performed as a method of determining whether compatibility can be achieved.

Thoroughly mix Standard Ottawa Sand, Reference Limestone Dust, and water. Weigh 190 ±1 g of sand mixture into a 6 oz ointment tin. Level surface of sa nd with a spatula. Place the compacting adapter on the sand surface and slowly, over a period of about 5 s, compact the sand until the 20 psi load is achieved, which is approximately 100 lb on the Rimac Spring Tester. Remove the compacting device, avoiding disturbance to 320 the sand surface. Quickly pour 12 g of the emulsion from a height of about 4 in. onto top of sand mixture. Start timer at start of pour. Stop timer when all emulsion penetrates into sand mixture. Delay 2 minutes then remove sand and mixture from one side of ointment tin, about 1/2 of mixture. Measure to determine average depth of penetration into sand mixture. Penetration time shall be 100 s or less; penetration depth shall be 6.0 mm or more.
