2022年6月7日 · This report, entitled Effects of Seasonal and Diurnal FWD Measurements on LTE of JPCP—LTPP SMP Data, analyzes the effects of seasonal and diurnal falling weight deflectometer (FWD) measurements on the load transfer efficiency (LTE) of jointed plain concrete pavements and develops general guidelines for conducting FWD deflection measurements.

This research addresses the critical issue of load transfer efficiency (LTE) in jointed plain concrete pavements (JPCP), with a specific focus on the role of dowel bars in ensuring optimal load transfer and providing a comfortable ride for vehicles.

2018年5月1日 · A jointed plain concrete pavement (JPCP) similar to the experimental pavement introduced by Shoukry et al. [8], [24] was modelled in this study. Model included a 4.6-m length slab that was jointed to two half-slabs.

A jointed plain concrete pavement (JPCP) was modeled in this study. The purpose of this work is limited to investigate the response of dowel JPCP under moving axle loads. The effects of concrete shrinkage during curing, moisture and thermal gradient were not …

2024年4月8日 · The performance of JPCP at the transverse joints is enhanced by providing steel dowel bars in the traffic direction. The dowel bar provides reliable transfer of traffic loads from the loaded side of the joint to the unloaded side, known as …

2018年9月1日 · The pavement deflections, which are usually measured by Falling weight deflectometer (FWD), are widely used to evaluate the load-carrying capacity of airfield jointed plain concrete pavement (JPCP), load transfer efficiency (LTE) of joints and voids underneath the slab (Civil Aviation Administration of China (CAAC), 2009, Federal Aviation ...

2018年8月20日 · Laboratory testing of JPCP with FRP and steel dowels focused on joint deflection and dowel strain data collection for determining Load Transfer Efficiency (LTE) and joint Relative Deflections (RD) under static and 5 million cycles of fatigue load corresponding to a 45 kN (10 kip) wheel load of HS-25 truck.

The primary objectives of this TechBrief are to evaluate the effects of seasonal and diurnal falling weight deflectometer (FWD) measurements on the load transfer efficiency (LTE) of jointed plain concrete pavement (JPCP) sections and to develop general guidelines for conducting FWD deflection measurements.

U.S. highways and roads made of jointed plain concrete pavement (JPCP) use load transfer devices, called dowels, across joints of a series of contiguous concrete slabs. Joints allow the movement and deformation of pavement to occur under mechanical loading and …

The joint spacing in jointed plain concrete pavement (JPCP) is continuously affecting long-term pavement behaviors. In this study, data from the Long-Term Pavement Performance (LTPP) program were analyzed, and the behaviors of JPCP with different joint spacings were compared to discover the joint spacing effects.
