9、aintenance and rehabilitation.Utilization of existing materials as the major component of thisprocedure may yield benefits in quality, economy, and preser-vation of natural resources. Recycling takes many forms; hot,cold, in-situ, central plant and surface. This practice may beused for various recyc
10、ling methods.4. Classification4.1 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 severalemulsified recycling agents. The groups should provide ad-equate freedom of selection for mos
11、t recycling methods.4.1.1 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.4.1.2 ER-2 and ER-3 are materials that combine rejuvena-tors and asphalt components in one emulsi
12、on. These softresidues are classified by low temperature penetration afteraging. They are typically used in recycling where there is anincreased demand for bitumen as when new aggregates areadded, or where immediate cohesiveness is desired.4.2 The choice of ER will be determined by the consistencyof
13、 the binder in the aged pavement, the methods of recyclingplanned, the amount, if any, of new aggregates, and otherdesign needs.5. Properties5.1 All emulsified recycling agents shall be homogenous,free flowing at pumping temperature, and shall conform to therequirements of Table 1.1This practice is

It would be prudent to have the chemical nature (float test for high float emulsions, particle charge test for cationicemulsions, or other tests as necessary) certified by the supplier.CRTFO shall be the standard. When approved by the engineer, the Thin Film Oven Test (Test Method D 1754) may be substituted for compliance testing.D5505062
