The objectives of the study were to determine the structural performance and load carrying capacity of thin RCC surfaced pavements under accelerated pavement testing (APT), and to determine the applicability of using a thin RCC pavement structure with cement treated or stabilized base as a design alternative for those low volume roadways having frequently heavy truck trafficking.

RCC quality control and quality assurance requires extensive testing of individual ingredients – aggregates, cementitious materials, water, and admixtures; and testing of the RCC mixtures to determine the properties of fresh and hardened RCC.
