About the Caterpillar AP-755 Asphalt Paver (B3T)

The Caterpillar AP-755 is a high-output tracked asphalt paver engineered for exceptional stability and material flow control. Powered by a robust industrial diesel engine, the AP-755 features a heavy-duty crawler undercarriage that provides superior flotation and traction on soft sub-bases. A hallmark of the B3T series is its advanced material delivery system, which utilizes independently controlled conveyors and augers to eliminate material segregation and maintain a consistent head of material in front of the screed. With dual operator stations and integrated electronic controls, the AP-755 is designed to meet the demands of large-scale infrastructure projects while ensuring maximum operator comfort and visibility.

Maintaining a B3T-prefix paver requires access to accurate factory specifications to handle its complex electronic-over-hydraulic systems. This manual ensures that every task—from calibrating the automatic grade and slope controls to rebuilding the hydrostatic propel motors—is performed to original equipment standards. Investing in this digital guide protects your machinery investment and ensures the reliability needed for high-stakes road construction contracts.
