Project description

The objectives of this research are to investigate factors that may impact roller compacted concrete (RCC) pavement performance, including, but not limited to, construction practices, mix design proportioning, joint spacing, cracking mechanism and combined temperature and loading effects; quantify the impact of different axle load magnitude on RCC pavement damage in term of fatigue cracking and load equivalent factors; evaluate the cracking mechanism and joint performance of RCC pavement relative to the performance of thin (less than 8 inch thickness) RCC pavements over different stabilized base material; develop representative performance prediction curves suitable for use in an RCC thickness design procedure; and develop an M-E RCC pavement thickness design procedure for the LADOTD and compare the actual versus predicted RCC pavement performance using the developed design procedure.
