Abstract:
Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative road paving
technology that can have significant advantages over traditional road paving techniques. Tests
have shown that UTCRCP can carry in excess of one hundred million E80s (standard 80 kN axle
loads). The laboratory tests used for quality control of conventional concrete are not adequate
to fully capture the effects of the steel fibres added to the high strength concrete used in
UTCRCP. In this study the concrete strength and fibre content were varied and the mechanical
and physical properties of the concrete were measured. The tests included compressive
strength, split cylinder, modulus of elasticity and four-point bending slab tests. The results
of these tests are reported in this paper, and the suitability and shortcomings of the tests
are discussed.
