Drop-On Aggregate

Drop-on aggregate is the controlled application of aggregate onto a binder or thermoplastic surface while it is still hot or tacky. It is used to improve texture and increase skid resistance once embedded and cured.

Aggregate is applied immediately after the binder or marking material is laid so it can embed before the surface sets. Correct timing and application rate are important to ensure consistent performance.

Drop-on aggregate is commonly specified within skid-resistant surface treatments and delivered as part of road marking operations using thermoplastic application equipment where required.
