benefits if used correctly in a pavement structure. As an alternative roadbed support over weak soils, LCC has_x000D_
been installed as pavement base material to provide a more stable and stronger foundation. It has been placed_x000D_
in a few pavement sections across Canada and preliminary information shows it can improve pavement_x000D_
performance._x000D_
However there is a lack of engineering data which quantifies the performance of this layer within the pavement_x000D_
structure. It is also unclear how it performs over time. This proposal is directed at quantifying performance_x000D_
through an integrated field and laboratory evaluation where the LCC is evaluated. There is a need to_x000D_
investigate and quantify the technical benefits, strength, stiffness, and vibrations of the LCC under cyclic traffic_x000D_
loading. In order to optimize the use of LCC as base material in pavement engineering, the Centre for_x000D_
Pavement and Transportation Technology (CPATT) at the University of Waterloo and the CEMATRIX_x000D_
(Canada) Inc. are collaborating to investigate the pavement structural benefits with the use of CEMATRIX_x000D_
LCC._x000D_
The following major tasks will be part of this research program: build a full scale instrumented pavement_x000D_
section with the use of various LCCs as base layers, instrument and evaluate thermal performance during_x000D_
winter conditions, and instrument and quantify potential benefits of dampening vibrations. In addition, the_x000D_
research will develop a pavement structure number and potential pavement layer thickness savings that can be_x000D_
achieved by using LCC. A finite element model will be built to simulate and predict the bearing capacities of_x000D_
pavements with various thickness of LCC at various locations (depth) to the base, and finally guidelines for_x000D_
LCC pavement and provide typical pavement designs with LCC for the usage in Canada. The designs will_x000D_
account for varying traffic loading and environmental conditions., program purpose french : Lightweight Cellular Concrete (LCC) offers potential structural, functional, construction, performance and cost_x000D_
