WALING-Sept. pp. Techniques and results of laboratory experiments on simulated continuously reinforced concrete slabs are given. Specimens 3 x 28 ft, 8 in. thick, were reinforced with deformed bars, variables being bar size, spacing and depth, and total percent of steel. The slabs, cast with preformed transverse cracks in the testing region, were tested on an elastic subgrade having a modulus of approximately 160 lb per cu in. Vertical static loads simulated traffic loads and horizontal longitudinal loads were used to simulate stresses induced by temperature changes. Results pertaining to slab deflections, crack widths, and stresses in reinforcement are emphasized. Significant findings are compared with field observations reported in the literature, and several criteria are suggested for optimum structural design of continuously reinforced pave- m e n t s .
