provides high-altitude advice - In 2018 Abatech reached for the
sky - providing paving advice with roads crossing the Andes in Chile.
The road pavement was at 16,500 feet - the highest road we have ever
worked on. This projected included the use of compaction aids
in the asphalt binder (bitumen) to assist with achieving density at
these high altitudes.
Abatech and the Asphalt Institute have been hosting the Rheobit training
courses for over 10 years. These courses developed by Dr. Rowe
with the assistance of Prof. David Anderson have been held in many
countries over the past 20-years. For latest course dates
please check our training page or the Asphalt
Institute web site. The most recent course was held in Lexington, Kentucky -
in October, 2018. The participants spent a week working in detail
with rheology of bituminous materials

Pavement evaluation studies
AGE PAVEMENT TESTING
pavement evaluation studies have involved analysis of
pavements associated with movements of the Space Shuttle from
the LAX airport on its way to its final museum destination
with our partners (see news-link)
and assessment of pavements around the launch facilities in
offers detailed pavement evaluation services in locations
around the globe.

Abatech working at Hanford, WA (July/August 2010-2019) - with MatCon
has been working on the QC of MatCon
cap installations at the Hanford nuclear reservation in the
State of Washington, USA. The work includes 1)
evaluation of base properties using deflection testing, 2)
mechanistic calculations of design life, 3) supervision of the
asphalt production and 4) lay-down quality control. This
site protects a series of underground storage tanks which are
potentially leaking contaminants into the ground water system
at the site. The protective cap will minimize this while
