EARLY PERFORMANCE OF SLURRY SEALS USED FOR PAVED ROAD MAINTENANCE IN MALAYSIA. PROCEEDINGS, SIXTH CONFERENCE, ROAD ENGINEERING ASSOCIATION OF ASIA AND AUSTRALASIA, 4-10 MARCH 1990, KUALA LUMPUR, VOLUMES 1 TO 5 AND POST CONFERENCE PROCEEDINGS
Following the introduction of slurry seals as a maintenance treatment for paved roads in Malaysia, it was found necessary to produce construction guidelines for their most cost effective use. To do this the Public Works Department embarked on a comprehensive study of the long term performance of different types of slurry seals under a range of pavement conditions and traffic levels. This paper describes the experimental design employed, the construction and the early performance of a general purpose slurry seal. The results show that this type of seal performs well when applied to uncracked asphaltic concrete surfacings but is ineffective in sealing even minor cracking at low traffic levels. The study has also shown that a general purpose seal reduces the rate of environmental ageing in the asphaltic concrete layer below the seal but that the bitumen in the seal itself ages rapidly despite its high bitumen content.
