Highway Department “must make everything certain”, need market, test data, and real
road data before using in Hong Kong
Since the British left the people have more freedoms which results in more
complaints. The noise around Hong Kong tends to be just above the acceptable level
and noise pollution is becoming more and more of an issue. Rubberized asphalt has a
significant effect on sound created between tire and road. Rubberized asphalt lowers
the sound produced by 3-5 decibels, which lowers the noise created to below
The future plan for rubberized asphalt will share costs between the Highway
and Environmental Departments. Phase 1 will use the Arizona mix and will be tested
to provide data for Hong Kong. It will start just after the New Year and last for one
year. Phase 2 will possibly use a mixture designed for Hong Kong.
Investors just recently built a large rubberized concrete mixing plant in Hong
Kong, which will lower the costs for future projects.
Mainland China has very high standards for construction projects. Although
they are maintained for national or high level projects the local authorities don’t
follow code because of high costs.
