• This paper described a simulative laboratory test to simulate traffic overcompaction using the gyratory compactor. During overcompaction, specimen heights were monitored to determine mix porosity. Mix permeability was measured before and after overcompaction. Resistance to overcompaction was assessed from changes in porosity, height and discharge time. The porosities of all mixes reduced continually until overcompaction ceased. The magnitude of porosity reduction of SLPA mix was highest when overcompacted at higher pressure and on smaller NMAS conventional mix. From the terminal percentage height reduction values, DLPA mixes were subjected to a higher degree of overcompaction compared to the corresponding SLPA mixes. In general, SBS modified mixes were more resistant to overcompaction compared to conventional mixes. The modified mixes also exhibit the lowest percentage change in drainage time.
