43Reflective cracking distresses frequently occur on the hot mix asphalt (HMA) overlay 44 due to the movements of the underlying portland cement concrete (PCC). Rubblization was 45 proven in North America to be an effective approach among slab fracturing technologies for 46 solving the premature reflective cracking problem. This paper presents the procedure of 47 applying the rubblization technology in HMA overlay design in a research effort in China to 48 develop the Chinese standard. In the study, the validity of rubblization was analyzed by a 49 trench survey and sieve tests; the layer moduli of the composite subgrade and rubblized 50 concrete slab were determined using FWD and plate bearing tests and a conversion chart; the 51 thickness design for the HMA overlay over the rubblized PCC pavement was conducted 52 using a Chinese version Mechanistic-Empirical design process; and finally the in-service 53 monitoring over the pavements built using the developed procedure was conducted to test the 54 validity of the procedure. 55 56
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
