Labour intensive construction

(Periods 1995 to 2000 and 2000 to 2003)

Various LIC options for the construction of bases were evaluated:

Clinker ash.

Waterbound macadam.

Composite macadam.

Emulsion treated gravel.

Emulsion treated clinker ash.

Conventionally constructed crushed stone base control section.

Testing included construction monitoring HVS testing and comprehensive laboratory testing.

Evaluate outstanding process in terms of ease of construction and quality control.

Test bearing capacity of various options relative to each other.

Cost/benefit evaluation.

HVS tests 394A4 to 408A4.

None of the LIC options performed as well as CSB control section.

Highest bearing capacity: ETB gravel and high density waterbound macadam.

Intermediate bearing capacity: Below density specification waterbound macadam and composite macadam.

Low bearing capacity: Clinker ash and emulsion treated clinker ash.

Cost/benefit results calibrated for effect of density.

Mechanistic - empirical guideline document for waterbound macadam material.
