The Cooling of Bitumen During Construction of Built-Up Roofing Systems presents a practical, math‑driven model for predicting how long hot bitumen takes to cool in roofing systems.
This edition explains how finite‑difference methods estimate transient heat flow to help ensure proper adhesion and uniform thickness.
Readers will find clear explanations of material properties, boundary conditions, and how factors like application temperature, air temperature, wind speed, and substrate type influence cooling time. The report also describes a computer program used to run these calculations and to compare results with temperature charts.
- Understand the key variables that control bitumen cooling in built‑up roofing.
- Learn how a computer‑based model predicts cooling times for common roof substrates.
- See practical examples drawn from configurations like polyurethane foam, glass fiber insulation, plywood, concrete, and steel decks.
- Gain a reference for estimating viscosity and adhesion concerns during construction.
Ideal for professionals and students working with roofing materials, thermal modeling, or construction heat transfer.
