Concrete pavement rehabilitation due to joint-related flaws at young-age is a usual procedure on highways, airports, and urban corridors in Brazil. As a more sustainable (in terms of longevity) alternative to jointed plain concrete pavements, a continuously reinforced concrete pavement (CRCP) was constructed in São Paulo. The length of the four sections was 50 meter each, short in contrast with traditional CRCP. Due to the lack of anchorage at the slabs end, the short CRCP cracking behavior was very different from traditional CRCP. This paper presents the updated crack map and the results of a dynamic load testing. The tests were conducted with a loaded truck at constant speeds of 10 km/h and 50 km/h, as well as during braking. Results pointed out that increasing the average speed does not affect the stresses values; however, it was observed that the braking action increases the stresses caused by the front axle and the opposite effect was recorded concerning the rear axle.
