- Falling Weight Deflectometer:
FWDs are test systems for performing non-destructive testing of
pavements and other foundation structures. The system develops forces from the acceleration caused by
the arrest of a falling weight and these forces are transmitted onto the surface of a structure causing it to
deflect as much as it would due to the weight of a passing wheel load. The deformation of the structure
is referred to as a "deflection basin" and a series of user positioned velocity sensors automatically
determine the amplitude and shape of this deflected basin. The deflection response, when related to
the applied loading, can provide information about the strength and condition of the various elements of
the pavement structure. Our staff members operate a state-of-the-art JILS Falling Weight Deflectometer which has been used for projects in Europe,
the Caribbean and the USA. Our staff have developed numerical procedures for pavement design and
is a leading organization in writing software applications. The DAPS software (Deflection Analysis of
- Light Weight Deflectometer:
LWDs (or dynamic loading plate) enable the determination of appropriate
stiffness of pavement foundations (modulus value) is critical in that it allows pavements to be designed
using analytical methods and/or methods such as the 1993 AASHTO method. All these methods make
use of a foundation modulus value in determination of the pavement structure.
Many methods exist to provide an estimate of the Efoundation of a road pavement. Methods such as
California Bearing Ratio (CBR) testing provide an empirical correlation to a modulus value and have
been in use for many years. More recently the Falling Weight Deflectometer (FWD) testing has become
the standard for assessing the stiffness of road foundations. However, the use of the FWD requires
that the site to be evaluated is relatively easy to access and can be reached with a vehicle/tow vehicle
in a reasonably cost effective manner. This is not always possible with remote sites and consequently
other methods are needed. This could involve the use of tests such as CBR and empirical correlations.
However, more recently sophisticated lightweight deflectometers (LWD) have become available that are
portable to remote sites, enabling direct computation of Efoundation values.
- Dynamic Cone Penetrometer:
This device can help to assess the strength of granular pavement layers
including soils and subbase materials.
- Pavement investigations:
Can involve a wide range of specimen collection followed by detailed chain-
of-custody documentation followed by various lab testing. Testing is supplemented by other studies such
as FWD, laser surveys, ground penetrating radar, DCP, light weight deflection testing, etc.
MMCE has access to a large range of laboratory testing procedures and uses the most sophisticated
analysis and integration of results to provide clients with a realistic and meaningful analysis of laboratory
