9、ls inN-Propyl Bromide3.Significance and Use3.1 Recycling of deteriorated asphalt pavements is beingused as a routine method of maintenance and rehabilitation.Utilization of existing materials as the major component of thisprocedure may yield benefits in quality,economy,and preser-vation of natural r
10、esources.Recycling takes many forms;hot,cold,in-situ,central plant and surface.This practice may beused for various recycling methods.3.2 This practice describes emulsified recycling(ER)agentsas belonging to three groups;ER-1,ER-2,and ER-3 as shownin Table 1.The range of recycling methods demands se
11、veralemulsified recycling agents.The groups should provide ad-equate freedom of selection for most recycling methods.3.2.1 ER-1 is a material whose main function is to rejuve-nate aged asphalt.The material is a petroleum derivative,andhighly compatible with asphalts.It is classified by viscosity.3.2
12、.2 ER-2 and ER-3 are materials that combine rejuvena-tors and asphalt components in one emulsified asphalt.Thesesoft residues are classified by low temperature penetration afteraging.They are typically used in recycling where there is anincreased demand for asphalt as when new aggregates areadded,or
13、 where immediate cohesiveness is desired.3.3 The choice of ER will be determined by the propertiesof the asphalt binder in the aged pavement,the methods ofrecycling planned,the amount,if any,of new aggregates,andother design needs.1This practice is under the jurisdiction of ASTM Committee D04 on Roa
