Method of protecting a surface with a silicon-slurry/aluminide coating [PDF]
, 1982 A low cost coating for protecting metallic base system substrates from high temperatures, high gas velocity oxidation, thermal fatigue and hot corrosion is described. The coating is particularly useful for protecting vanes and blades in aircraft and land

Performance of Asphalt Rubber Mixture Overlays to Mitigate Reflective Cracking
Materials, 2022 Adequately predicting overlay behaviour is essential for flexible pavement rehabilitation to reach the predicted lifespan. Reflective cracking is one of the main failure mechanisms affecting overlay performance. This failure may occur due to cracks in the lower layers that propagate to the overlay due to traffic loads, temperature variations, shrinkage

Laboratory Validation of Surface-Initiated Transverse Cracking of Asphalt Pavement
Applied Sciences, 2020 Field pavement transverse cracking typically can be grouped into two categories, namely thermal cracking that initiates at the surface of the pavement and propagates downward, and reflective cracking that initiates at the pavement layer above the ...

Cracking and Seating to Retard Reflective Cracking - Hamilton County, HR-277, 1993 [PDF]
, 1993 The crack and seat (C & S) method of rehabilitating concrete pavements has been proposed to reduce the incidence of reflective cracking in asphalt overlays.
