A numbe
2、r in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice identifies emulsified petroleum products that may be used as recycling agents in recycled mixes. Thesematerials are classified
3、 by viscosity or by low temperature penetration after aging.1.2 This practice addresses emulsified materials designed specifically for use in recycling. The use of emulsified materials forrecycling shall not be limited to this practice. For instance, the emulsified asphalts specified in Specificatio

No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of
5、 this standard to consult and establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use.1.3 This practice addresses emulsified materials designed specifically for use in recycling. The use of emulsified materials forrecycling shall not be

15、9428-2959. United States13. Significance and Use3.1 Recycling of deteriorated asphalt pavements is being used as a routine method of maintenance and rehabilitation. Utilizationof existing materials as the major component of this procedure may yield benefits in quality, economy, and preservation of n
16、aturalresources. Recycling takes many forms; hot, cold, in-situ, central plant and surface. This practice may be used for various recyclingmethods.3.2 This practice describes emulsified recycling (ER) agents as belonging to three groups; ER-1, ER-2, and ER-3 as shown inTable 1. The range of recyclin
17、g methods demands several emulsified recycling agents. The groups should provide adequatefreedom of selection for most recycling methods.3.2.1 ER-1 is a material whose main function is to rejuvenate aged asphalt. The material is a petroleum derivative, and highlycompatible with asphalts. It is class
18、ified by viscosity.3.2.2 ER-2 and ER-3 are materials that combine rejuvenators and asphalt components in one emulsified asphalt. These softresidues are classified by low temperature penetration after aging. They are typically used in recycling where there is an increaseddemand for asphalt as when ne
19、w aggregates are added, or where immediate cohesiveness is desired.TABLE 1 Specifications for Emulsified Recycling AgentsTests TestMethod ER-1 ER-2 ER-3min max min max min maxOn emulsionViscosity, 50C, SFS D244 100 20 450 20 450Sieve, % D6933 0.1 0.1 0.1Storage stability,24 h,%D6930 1.5 1.5 1.5Resid
