Summary: The study aimed to determine the optimal design of stone matrix warm mix asphalt containing crumb rubber modified binder (CRMB) using response surface method (RSM). Production temperature and the content of polyethylene wax and CRMB were considered as independent variables. Moisture sensitivity, flow number, resilient modulus, and critical stress intensity factor were used as response variables to determine the optimal design. The results showed that the prediction models of response variables can predict the performance results accurately. The optimal design of stone matrix warm mix asphalt containing CRMB at 135°C, 7.02% CRMB, and 2.1% polyethylene wax with a desirability of 0.765 were obtained using predictive models.

Summary: When studying paintings with active infrared thermography (IRT), lock-in thermography (LIT) showed advantages over pulse thermography (PT) in minimizing temperature fluctuations and providing higher contrast and less noise in phase images. However, PT was better at showing the upper paint layer, which is important for observing subsurface defects or the support structure. The influence of camera spectral range on the results was also investigated, with the addition of a long-pass filter eliminating direct reflection artifacts caused by halogen light sources when using a mid-wave infrared (MWIR) camera.
