Civil Infrastructure System Laboratory


Lab Mission

The purpose of the CISL is to test civil infrastructure elements under full-scale loading.

Lab Capabilities

The facility consists of a test frame in which a bogie with dual wheels can move forward and backwards while a load is applied by means of two main longitudinal girders. Tests can be conducted on three test pits. Lateral traffic wander can be applied in 0.5 in. increments, to a maximum wander of ± 24 in to simulate actual highway truck traffic distribution in the lane. The temperature of the pavement can be controlled within the range of -10°F to 140°F.

Lab Equipment

The wheel assembly consists of a single or tandem axle with airbag suspension. The wheel assembly is an actual bogie from a standard truck. Loading of the axle is achieved by varying pressure in the suspension system. At the end of the travel distance, an energy absorption and release system transforms the kinetic energy of the carriage into potential energy in the springs; the springs are used to launch the bogie in the opposite direction. It is possible to achieve simulated one-way traffic through a hydraulic pump that can lift the wheels off the pavement surface.

Partners

Research in the CISL is conducted as part of the Midwest States Accelerated Pavement Testing Pooled Funds Program (current participating states: Iowa, Kansas, Missouri and New York).

Current and Past Work

  1. Accelerated Pavement Testing of Low-Volume Paved Roads with Geocell Reinforcement
  2. Accelerated Pavement Testing of Unpaved Roads with Geocell Reinforcement
  3. Verification of Mechanistic-Empirical Design Models for Flexible Pavements Through APT Testing
  4. Thin Bonded Rigid Overlay on PCC and HMA Pavements
  5. Evaluation of Chemical Stabilized Subgrade Soil
  6. Performance of Foamed Asphalt Stabilized Base in Full-Depth Reclaimed Asphalt Pavement

Falling Weight Deflectometer Calibration Laboratory


Lab Mission

To calibrate falling weight deflectometer following SHRP/LTPP protocol.

Lab Capabilities

This is a calibration facility for the Falling Weight Deflectometer (FWD). The calibration facility was built as per the SHRP FWD calibration protocol which was originally developed by the Strategic Highway Research Program (SHRP), now administered by the LTPP Division of the FHWA.

Lab Equipment

Lab equipment includes the Calibration Floor, Block, Beam and Data acquisition equipment.

Partners

The lab has been used to provide calibration services to the Kansas Department of Transportation (KDOT)

Current and Past Work

Provided calibration services to KDOT (1998-2007).

Structural Testing Laboratory


Lab Mission

This facility is used for laboratory testing of structural elements.

Lab Capabilities

The structural engineering laboratory has been used extensively over the last decade for research on fiber-reinforced plastic (FRP) bridge decks and prestressed concrete bond research.

Lab Equipment

The laboratory has a 4-ft-thick concrete reaction floor with two 120,000-lb load frames, a 400,000-lb universal test machine (UTM), a 20,000 UTM, and two MTS fatigue-rated load frames. This laboratory is served by an MTS Flextest digital servo-control capable of controlling four simultaneous stations. Specialized set up includes two 3 ft x 5 ft structural mounting tables with continuously-drilled two-inch-thick solid steel tops that allow for a variety of structural testing configurations.

Partners

The lab has conducted a great deal of research of the Kansas Department of Transportation (KDOT).

Transportation Materials Laboratory


Lab Mission

This lab facilitates research and training in the Superpave system for performance-grade (PG) asphalt binder and mixes developed by the Strategic Highway Research Program (SHRP).

Lab Capabilities

The lab enables pavement material researchers at the Department of Civil Engineering at KSU to conduct research on various aspects of Superpave PG binder and mixes. The Department of Civil Engineering also trains engineers and technicians from KDOT and the industry on this system as a part of its extension activities. The advanced asphalt laboratory is heavily used in research as well as in a graduate-level bituminous materials class. The Superpave laboratory is also used in research as well as in graduate and undergraduate-level classes.

Lab Equipment

Lab equipment includes a Dynamic Shear Rheometer, Bending Beam Rheometer, Rolling Thin Film Oven, Marshall molds and hammer, Marshall stability tester, Superpave Gyratory Compactors, Binder ignition oven, Linear Slab Compactor, Hamburg Rut Tester, IPC Universal Testing Machine (UTM-25).

Partners

Research partners include:

  1. Kansas Department of Transportation
  2. Kansas Asphalt Pavement Association
  3. New York State Department of Transportation

Current and Past Work

This lab has recently been used for the following research projects:

  1. Rehabilitation of Ultrathin Bonded Bituminous Surface
  2. Structural Characteristics of Aged Hot-Mix Asphalt Pavements
  3. Implementation of the 2002 AASHTO Design Guide for Pavement Structures
  4. Investigation of 4.75 mm NMAS Superpave Mixture in Kansas.
  5. Design of Seal Coat
  6. Investigation of Design of Seal Coats with Light Weight Aggregates
