A STUDY ON USING SPRINKLE TREATMENT TO IMPROVE BITUMINOUS SURFACINGS. PROCEEDINGS, SIXTH CONFERENCE, ROAD ENGINEERING ASSOCIATION OF ASIA AND AUSTRALASIA, 4-10 MARCH 1990, KUALA LUMPUR, VOLUMES 1 TO 5 AND POST CONFERENCE PROCEEDINGS

Sprinkle treatment is a technique that applies a thin layer of highly polish-resistant precoated aggregates to the surface of a freshly placed, hot-mix wearing course, with a view to embedding into the surface during the rolling operation. This study investigates the effect of sprinkle treatment on durability of bituminous surfacings as regard skidding, stripping, and hardening. Granite, steel slag and a mixture of both are used as sprinkle aggregates. Sprinkle aggregates are precoated with penetration grade bitumen and its blend with either 5 per cent of natural rubber (discarded truck tyre) or 5 per cent of lime by weight of bitumen. From the laboratory test results, sprinkle treatment seems to offer two fold benefits to bituminous surfacings. Firstly, it provides an improved skid resistant surfacing, especially in areas where polish-resistant aggregates are not readily available in sufficient quantities or are expensive. Secondly, the treatment is able to improve the durability by reducing the hardening process of the bitumen and reducing the stripping tendency.
