Compare Thermo-Lay heated asphalt patchers, LeeBoy Rosco RA-400 spray-injection patchers, and LeeBoy HB4T hot boxes for Texas road maintenance crews.
Use hot mix from a Thermo-Lay unit when crews need permanent repairs with controlled material temperature and chute-fed placement.
Use an RA-400 when one operator needs to clean, tack, inject aggregate/emulsion, and dust coat from the cab.
Use an HB4T when the crew already places and compacts manually but needs a reliable 4 ton hot box trailer.
Buying guide
Pothole repair equipment gets confusing fast because a hot box, spray-injection patcher, and heated asphalt patching machine solve different problems. Start with how your crew works, then size the machine.
Machine lineup
A Thermo-Lay truck is the best fit when pothole repair is a daily workload and the crew needs one dedicated, fully integrated asphalt patching unit.
Thermo-Lay trailers give crews towable permanent patching capability without dedicating a truck chassis to asphalt repair.
Thermo-Lay hook-lift units let a fleet turn an existing hook-lift chassis into a self-contained asphalt patching truck when road repair work comes up.
Thermo-Lay slide-in units drop into a dump truck or plow truck body, giving crews a self-contained asphalt patcher without permanently converting the truck.
The LeeBoy Rosco RA-400 is a one-person spray-injection patcher for high-output pothole repair from the driver seat.
The LeeBoy HB4T Hot Box keeps plant mix hot, warms cold mix, and gives contractors or municipalities a compact 4 ton material support trailer.
