Loss On Heating / Thin Film Oven
Specification:
This dual purpose oven is designed to determine the loss in weight
of bitumen and flux oils (Loss on Heating test) and the effect of heat
and air on asphaltic materials (Thin Film test).
The unit is heavily insulated and has a double glass door for
viewing the test chamber thermometer and samples.
Temperature is controlled at 163° C ± 1° C by means of a
variable temperature controller and thermostat. Two rotating
platforms are supplied with each oven: One accepts 9 standard
penetration cups for the loss on heating test, the other accepts two
140mm diameter test pans for the thin film test. The platforms are
rotated at 5 to 6 rpm by an external motor.

manual compaction and an even degree of compaction is
achieved. The driven mechanism lifts the weight of 4.5kg and
drops it through a correct height of 457 mm.
The rammer foot is removable, which facilitates preheating. A
compaction pedestal with specimen holder is fixed to the base. An
Automatic Blow counter enables the number of blows to be present
before each test and automatically stops the machine on
completion. Suitable for operation on 230 V, 50 Hz, Single
Phase, A.C. supply
Rolling Thin Film Oven
Specification:
The superpave PG binder specification looked for tests
which would closely simulate field performance. Hotmix
asphalt binder experiences significant aging during the
manufacturing and laying process. Investigating this
phenomenon within a laboratory environment, with a
repeatable and simple test is very useful within the design
process. The rolling thin film oven (RTFO) test is used to
measure the effect of heat and air on a moving film of semi-solid asphalt binder. The results of this treatment are
determined from measurements of the binder properties
before and after the test. Repeatability of the test is directly
related to the accuracy with which the oven temperature
can be maintained and the reproducibility of the thermal
rise time of the system. Super accurate P.I.D. Controller
Asphalt Content Tester
Specification:
Asphalt Content Tester is used to determine the asphalt content of hot mix
asphalt(HMA) and pavement samples by removing the asphalt in an ignition
furnace by means of sample heating not by means of solvent.Sutiable for operation on 415 V
50 Hz 20 ampere three phase ac power supply. Maximum weight specimen
is 4000 gms, suggested weight of specimen is 1000 gms to 1500 gms.
Balance provided is 10 Kg x 0.1 gms, working temperature of furnace is
800° C, standard working temperature is 538° C. Testing time is 20-30
minutes. Size of the furnace: 350 mm length x 430 mm width x 300 mm
height.
Asphalt Mixer Theoretical Density Meter
Specification:
This equipment is used for determination of theoretical density of
asphalt mixer by vacuum method for application such as asphalt
mixer design, road condition investigation ,calculation of porosity
and compactness in road construction quality management. This
equipment has a main body fitted with a vacuum gauge of Wika
make Germany, 2 vacuum containers made of acrylic pipe & a
vibratory table under with complete control panel. The Vobratory
table operates on manual and automatic mode to release the
entrapped air from the asphalt sample kept inside the vessels. It is
suitable to work on 230 V AC single phase 50 Hz. Vacuum range
0-100 KPA (0-750 mm Hg) vibration loading is 10 kg. no of
samples tested is 2.
Travelling Beam Device
Specification:
The Travelling Beam Device is used to check for any
irregularities in both concrete and bituminous road
surfaces. A sensing unit comprising a wheel connected to
an indicator provides a magnification of 4:1. Deviation of
the surface from a straight-line is shown on a scale
calibrated in increments of 2 mm in the 0-10 mm range
and 5 mm increments in the 10-25 mm range. It comprises
a manual dye marker which is used to mark irregular
surface sections when found.
Straight Edge (3 Meters)
Specification:
A straight edge approximately 3 meters in length may be
used to determine lateral surface regularity of a road
surface. This lightweight apparatus is made up of mild
steel or aluminum as per customers requirement and is
equally supported at both ends producing a set height
between the road surface & the beam. Any vertical
irregularity is measured using incremented wedges.
