Abatech and the Asphalt Institute recently hosted the 12th Rheobit training
course that was held in Lexington, Kentucky - September 29th to
October 3rd, 2014. The participants spend a week working in detail
with rheology of bituminous materials.

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) - with MatCon
has been awarded a contract for quality control of the MatCon
cap installation 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
the tanks and remediated.

Dr. Rowe is presenting ideas on Interrelationships
in Rheology for Asphalt Binder Specifications.
DAPS (Deflection Analysis of Pavement Structures) has been
updated (10/14/2013). The newer version (1.6.0 DLL v.29) includes; 1) Lower limit for AC stiffness cutoff reduced to 2000 MPa (with message), 2) User's Std. Axle setting was not being remembered between sessions (corrected), 3) For JILS
FWD M2 data, put milepost into chainage, 4) Now getting two temperatures into the listing for the particular case of
JILS FWD M2 data, 5) Recognizes JILS FWD M2 data format (in addition to M3 and
M5), 6) the software has been updated to make more
compatible with 64bit O/S.
