Behaviour of Rolled Compacted Concrete Results of Measurements in Experimental Pavements

Precise measurements on experimental ruil scale pavements demonstrate that curling and warping phenomena arc affecting similarly the RCC and the conventional PCC pavements of equivalent designs: with «light differences in deflections and joint openings mainly attributed to different adherence at the slab-base interface. After IS months exposed to drying shrinkage. the 3-5 m spacings of transverse cracking developed spontaneoualy in the RCC without traffic, result to be similar to the typical joint spacing of Chilean PCC pavements. A qualitative evaluation is abo presented of the surface regularity on other 3 experimental RCC pavements exposed to traffic without any surface treatment.
