Rosco

Rosco has long been tied to the surface-treatment side of road maintenance: asphalt distributors, tack distributors, maintenance distributors, and chip spreaders that help crews extend road life instead of waiting for full reconstruction.

For Closner customers, the Rosco conversation usually starts with the Maximizer distributor family. The Max 3B is the model we see most often because it gives contractors, counties, and municipalities a serious fully circulating extending spray-bar distributor without jumping straight to the largest Max 4B package.

The Rosco page stays focused on distributor and chip-seal workflow: Max 2B, Max 3B, Max 4B, PR900, LeeBoy tack distributor packages, and the CSV chip spreader. These are the machines that support tack, fog seal, seal coat, chip seal, and route-based maintenance across Texas.
