Wheel Path Wandering Based On Field Data
<p>The position and width of wheel path on a pavement lane is an important consideration in conducting pavement distress survey, especially for distinguishing longitudinal cracking from fatigue cracking. Currently, the widely used wheel path definition is derived from the LTPP distress manual with …

Cracking and Roughness of Asphalt Pavements Constructed Using Cement-Treated Base Materials
… and high-severity block, fatigue, longitudinal (wheel-path and non-wheel-path), and transverse cracking in AC pavements constructed using CTB layers. Investigation of the relationships between CTB modulus and the development of roughness and cracking is recommended for further study.

Crack detection technique for reinforced concrete bridge decks
… and monitor the growth of cracks along the wheel path. The system consists of 30 crack-meters embedded in concrete over the bottom layer of the reinforcement. The crack-meter readings are automatically collected every 20 minutes together with the readings from other sensors that were placed …

Corrosion Assessment for Failed Bridge Deck Closure Pour
… section punched through. It was part of the left wheel path of the south bound right lane of the bridge deck. The bridge deck was replaced in 1992 as part of a bridge rehabilitation project, epoxy coated reinforcement were used as the reinforcing steel. Four slabs from the bridge deck, containing …

The Development of Measurement and Characterization Techniques of Road Profiles
… systems measure separate 2-D profiles in each wheel path of the vehicle. The equipment setup and signal processing techniques are discussed, as well as future improvements and applications of this enabling technology. The second part of this work develops a method of characterizing …

A Galerkin Approach to Define Measured Terrain Surfaces with Analytic Basis Vectors to Produce a Compact Representation
… It is also desirable to develop a compact, path-specific, terrain surface representation that exploits the inherent anisotropicity in terrain over which vehicles traverse. In order to obtain this, a set of analytic basis vectors is formed from Gegenbauer polynomials, parameterized to …

Applications of Computer Vision Technologies of Automated Crack Detection and Quantification for the Inspection of Civil Infrastructure Systems
… length, orientation, texture, intensity, and wheel-path location, crack detection accuracy was evaluated to find the optimal sets of crack features. Lab and field test results of different inspection applications show that proposed compute vision-based crack detection and quantification …

Mechanistic-Empirical Pavement Design Procedure For Geosynthetically Stabilized Flexible Pavements
… surface thickness was 78-90 mm. The outside wheel path of the inner lane was instrumented with strain gages, pressure cells, piezoelectric sensors, thermocouples, and moisture sensors. Section performances based on the instrumentation response to control and normal vehicular loading indicated …
