The increasing challenge for road engineers to maintain road performance,
work within limited budgets and meet the tightening of environmental regulations
has opened the door for the introduction of other kinds of soil additive
stabilizers including highly cost-effective liquid enzyme formulations.
Since the advent of soil stabilizers, road executives and construction
engineers have sought to learn if stabilizers actually work as advertised
and whether there is a performance difference between the various soil
stabilizer brands on the market. The World Bank, with the implementation
support of the Government of Paraguay, funded a definitive study of the
effectiveness of new soil stabilization technology on secondary or rural
roads and made the results available to the world road construction community.
This World Bank study, "Octavo Proyecto de Carreteras - Prestamo
del Banco Internacional de Reconstrucción y Fomento (BIRF) 3685-PA,
shows that some soil stabilizers consistently showed superior performance
compared with untreated, adjacent test road sections. It also proved that
there was a significant performance difference between the soil stabilizer
brands that were used in the test.
