studies programme that was established under the Strategic Highway Research Program (SHRP), has four regions in North America such as North Atlantic, North Central, Southern and Western and the company's contract covers all of these.

program developed several prediction models using artificial neural networks (ANN) to estimate the dynamic modulus of HMA mixes.
The following additional input variables have to be taken into account for the LTPP
database contains material, design and construction data including physical inventory data, material properties from in-situ and laboratory tests (LTPP
program was a significant initiative that was developed in the light of such research and resourced to face these challenges in a new way.
DataPave Online also provides user-friendly ways to explore, extract, and organize the LTPP
data for analysis.
In a SHRP study conducted by Simpson et al., based on early analysis of Long-Term Pavement Performance (LTPP
) general pavement studies data, JPCP faulting models are developed, which are empirical models .

The model coefficients were determined from the triaxial repeated loading tests and then calibrated by Accelerated Pavement Tester's (APT) and Long Term Pavement Performance (LTPP
The Strategic Highway Research Program (SHRP) adopted the FWD device as a key piece of equipment for assessing a structural capacity of long-term pavement performance (LTPP
) test sections.
