GEO320 MRH Asphalt Bitumen has gone through vigorous testing since 1987 and presented here are the latest findings made by ARRB on 16 August 2002. GEO320 MRH was tested by ARRB Transport Research to compare its performance properties with normal road grade residue bitumen, in this case the (Shell Class 320). Standard tests used to characterize bitumen to Australian Standard AS2008 were applied to both products. 1) "GEO320 was less soluble in standard laboratory solvents, the reduced solubility is noted to be advantageous to the end-user" 2) "The GEO320 durability is significantly better than typical class 320 bitumen. 3)" Fatigue performance was better than class 320 bitumen, this binder gave fatigue performance similar to a moderately modified PMB, a good result and better than typical CL320 bitumen" 4)" GEO320 handles like a conventional class 320 bitumen" 5)" No significant fumes were noted during the high temperature handling phase a mass loss of only 0.5% was measured which is on the limit (minimum volatile emissions) for Austroads specified polymer modified binder " 6)" GEO320 is not of petrochemical origin" 7)" GEO320 behaves like PMB's and lower temperatures were required to overcome the high apparent elasticity".
