Reconstruct full slope and deflection profiles, identify anomalies, and improve confidence in your TSDD data using our physics-based AI engine and three-layer slope QA framework.
With deep experience in pavement design and structural analysis, we interpret slope and deflection results, backcalculate layer moduli, and support network- and project-level decision-making.
We partner with researchers, vendors, and agencies to develop advanced tools for interpreting large-scale structural data from TSDD. Bring us in early to shape analysis strategies, enable deeper insights, and deliver actionable outcomes.
Answers to questions you might have about SPADE
SPADE (Slope and Physics-informed Analytics for Deflection Estimation) is an AI-powered tool that reconstructs full slope profiles from individual TSDD deflection slope measurements and calculates full-surface deflection curves. It enables users to perform quality consistency checks on measured slope values, ensuring more reliable data for analysis and decision-making.
SPADE is built for TSDD data providers, consultants, and transportation agencies (DOTs) aiming to enhance deflection analysis, perform automated slope quality checks, and extract deeper insights from pavement deflection data. Vendors can also integrate SPADE into their workflow before data delivery, improving quality and value for end users.
Unlike traditional deflection methods that rely solely on raw sensor readings, SPADE uses a physics-informed machine learning model trained on slope profiles. It reconstructs complete slope curves—even when some sensors show anomalies—and performs automated consistency checks to flag inconsistencies in measured deflection slopes.
SPADE has been benchmarked using both field and synthetic datasets and shows strong agreement with full-reference  profiles. Its physics-informed model reconstructs a complete deflection profile from individual TSDD slope measurements—even when some sensors show anomalies. While SPADE can mitigate inconsistencies in the data, the final accuracy still depends on the quality and reliability of the measured slopes.
