AB  - RILEM TC-279 WMR task group TG 1 studied the performance of
waste Polyethylene (PE) in bituminous bituminous binder and bituminous mixtures.
Several laboratories participated in this study following a common protocol.
Locally sources aggregates and bituminous binder and same source of waste
PE and were utilized. The binder experiments showed that at high temperatures,
using MSCR tests, PE modified blends had better resistance to permanent deformation
in comparison to the non modified binder. Whereas at low temperatures,
using the LAS tests, fatigue performance of the PE blends could withstand
more loading cycles under low strains; however, it could sustain less loading cycles
under high strains due to the increase in brittleness. Dry process was used
for the mixture experiments in order to bypass the stability and inhomogeneity
experience that was observed at the binder scale. The PE modified mixtures
showed improved workability and increased strength. The higher the PE dosage
the higher the ITS increase with respect to the values measured for the control
materials (i.e., without any plastic waste) thanks to the improved cohesion of the
plastic modified mastic. The stiffness experiments showed an improved performance
with a lower time dependence and a higher elasticity that were often
measured when plastic was added. The cyclic compression tests demonstrated a
reduced creep rate along with a higher creep modulus thanks to the addition of
PE; similar conclusions can be drawn from the experimental findings coming
from wheel tracking test. Furthermore, acceptable and often improved moisture
resistance was observed for PE modified materials.

AB  - This recommendation is based on the results of an inter-laboratory study organised by the RILEM technical committee TC 264-RAP "Asphalt Pavement Recycling"—Task Group 3 (TG3) focusing on Asphalt Binder for Recycled Asphalt Mixture. The TG3 aimed to evaluate the effect of a specific family of materials known as asphalt recycling agent (ARA) on the aged binder under different configurations. Even though ageing is an irreversible phenomenon, effective ARA must have the capability to improve the flexibility of the bituminous materials and their resistance against cracking susceptibility with no adverse effect on the rutting resistance of pavements containing reclaimed asphalt. A total of 17 participating laboratories analysed the properties of binder blends composed of aged binder from reclaimed asphalt in three different contents (60, 80, 100%), ARA and virgin binder. The physical properties of the blends were thoroughly evaluated through traditional and rheological binder testing. This recommendation proposes to restore the original material properties at low and intermediate temperatures (i.e. cracking resistance) while balancing the high-temperature characteristics (i.e. rutting susceptibility) with durable impact throughout the progression of ageing phenomena. Therefore, using of the Dynamic Shear Rheometer is foreseen as a more suitable and sustainable means to evaluate binder blends containing an asphalt recycling agent. Compared with conventional testing, the proposed approach requires fewer materials while resulting in a faster experimental procedure with one single test.

AB  - The use of rejuvenators has seen a consistent increase over the years in  the  asphalt  pavement  industry.  This  is  due  to  the  need  for  maximizing  the  demand  for  incorporating  a  higher  amount  of  Reclaimed  Asphalt  (RA)  in  the  pavement asphalt mixtures. In order to tackle this challenge, the Task Group 3, focusing on asphalt binders and additives, of the RILEM TC RAP conducted an interlaboratory  activity  to  evaluate  the  effect  of  aging  on  blends  of  virgin  and  rejuvenated RA binders. A set of conventional tests including penetration value at  25  °C, softening  point  temperature  and  rheological  measurements  by  means  of Dynamic Shear Rheometer (DSR) were selected to involve a large number of participants.  A  binder,  recovered  from  field  RA,  was  treated  with  a  bio-based rejuvenator and blended with a virgin binder to simulate recycling at three different  percentages  60  %,  80  %,  and  100  %.  These  blends,  as  well  as  the  pure  virgin  binder,  were  next  short  and  long  term  aged  and  tested  to  evaluate  the  changes  in  the  corresponding  properties.  Relatively  consistent  results  were  obtained for the entire set of blends. The aging of combined rejuvenated RA and virgin  binders  was  comparable  to  that  experienced  for  the  pure  virgin  binder.  DSR data provided a more precise evolution of the impact of aging on the materials.

AB  - The  use  of  Reclaimed  Asphalt  (RA)  into  new  asphalt  mixtures  becomes  an  inevitable  step  for  sustainable  infrastructure.  Saving natural,  non-renewable materials, such as bitumen and aggregates, the asphalt industry is moving forward with more recycling. Although asphalt is a 100% reusable material, high recycling rates are not yet easily achievable due to many limitations, going from technical specifications through RA properties to asphalt plant capabilities. The  rate  of  RA, which  may  be  used  within  a  new  asphalt  mixture,  depends  on  many aspects: variability, moisture and fines contents, presence of polymers, brittleness of aged binder, etc. The latter is directly linked to the degree of the RA binder ageing. As higher RA content increases the asphalt mixture stiffness, the material becomes more brittle and prone to cracking. The use of recycling additives is  taking recycling to the next level by solving these issues. With the growing  need  of  the  industry  for asphalt  recycling  agents,  many  products  have  appeared on the market with different effects. In this study, three asphalt recycling agents (two industrial and one alternative) were used as rejuvenators.  Blends with50% of rejuvenated RA binder (RAb) and virgin binder were subjected to different ageing levels: short (RTFOT), long (PAV for 20h) and prolonged (PAV for 60h). After each ageing level, physical, rheological and chemical properties were evaluated addressing the ageing behaviour of the additives used. Testing results showed that one industrial additive lost almost all its properties after prolonged ageing, while the other additives showed comparable results with the second industrial product.
