Abstract: A bridge paving machine and method for paving a 3D design without vertical profile rails includes converting a desired design into a 3D surface model to account for certain factors known to cause deviations in the paving processes and paving the 3D surface model in the expectation that factors will cause the 3D surface model to deflect into the desired design. An on-board computer system adjusts the 3D surface model in real-time to correct for on-site variables. The on-board computer system receives data from various external sensors, including deflection sensors fixed to girders in the bride structure, and paving machine-based sensors, and uses various predictive models to predict surface deflection based on the sensor data. The 3D surface model is continuously updated based on the predictive models and actual measured deflections.

Abstract: A method and system for detecting road intelligent compaction index, so as to solve the problem of inaccurate use of a road intelligent compaction index due to the fact that existing harmonic ratio indexes do not consider the influence of a non-integral period on the accuracy and also do not consider a higher harmonic. According to the disclosure, a relative relationship between amplitudes of the higher harmonic and a fundamental wave in an acceleration time domain signal is considered based on the related art, the amplitude of the higher harmonic is introduced into a main body road intelligent compaction index of an road intelligent compaction index, and a precondition for the use of the road intelligent compaction index of the main body is established, that is, a machine-material decoupling control the machine-material decoupling control index.

Abstract: A method for operating a road paver comprises paving a road surface with the road paver along a road bed, wherein a paving screed of the road paver is drawn over the road bed along a paving direction of travel. The following steps are performed using a curve correction unit: determining a value defining a steering angle of the road paver; calculating based on the determined value an expected offset of the paving screed, which results from a yawing movement of the road paver during steering with the steering angle defined by the determined value; and automatically correcting a lateral extension position of at least one lateral extension part of the paving screed based on the expected offset, so that the offset is compensated.

Abstract: A method for screeding of an uncured concrete surface includes providing a screeding machine and a control. The uncured concrete surface is screeded and the control processes data captured by the sensors while the screeding machine is screeding the uncured concrete surface. While the screeding machine is screeding the uncured concrete surface, and responsive to data processing by the control of data captured by the sensors while the screeding machine is screeding the uncured concrete surface, the control estimates a flatness or levelness or quality of the surface of the concrete surface being screeded. The control may generate an output indicative of the estimated flatness or levelness or quality of the surface, and/or a display may display information associated with the estimated flatness or levelness or quality of the surface.

Abstract: A system and a method for monitoring a condition of a paving machine. The system includes a screed plate and a heating element for heating the screed plate. The system also includes a controller configured to determine a heat-up time for the screed plate and compare the heat-up time to a predetermined time. The controller is further configured to provide a signal indicating that the screed plate needs to be replaced if the heat-up time is less than or equal to the predetermined time.

Abstract: A screed assembly for a paving machine includes a main screed unit having a first section and a second section. A hinge assembly located above the main screed unit pivotally couples the first section with the second section. The first section and the second section rotate around a horizontal axis passing through the hinge assembly. A seal member located between the hinge assembly and the main screed unit covers a gap defined between the first section and the second section below the hinge assembly such that the seal member covers the gap and laterally extends beyond the gap above the first section and the second section. A pair of heating components attached to the first section and the second section heats the first section and the second section.
